As I said earlier, the microphone's rapture timing can be very accurate. As for the distribution of the slips, it might change a bit. If we change the orientation, or if we change the fault geometry, maybe the slip distribution will also change, for example, if the rapture speed is changed, for example, 1 km, 2 km, or 3 km, maybe there is a slight variation, maybe not too extreme, but if we can try several models, we can later try to validate them with other data, for example, with insar data because insar provides constraints. For the displacement, we can try using ISAR data, because there was also a presentation yesterday from Mr. Irwan Melano, the GNSS data on Flores Island has been processed, maybe in the future it can be used to validate the fault model. Then eh of course tsunami data. So if Insar and JSS are to constrain the fault and slip that is under the island. If the tsunami data can provide constraints on what fault slip is offshore, right? Maybe that's all from me, thank you. Okay, thank you Mr. Dito Busman for the explanation regarding, eh, from the tsunami aspect, how to carry out tsunami hazard probistics in the affected areas. We apologize that Zoom is limited to 100 participants. So sorry for those who can't get in. ee we have prepared ee YouTube link yes. Okay, later the committee will be able to convey it via the chat column, okay? So that participants who may have difficulty logging into e Zoom can follow the continuation via e. OK, for the last speaker, I invite Mr. Astika, is he still present ? Mas Faiz can you hear my voice? Okay, sounds good. OK, I'll read the brief description of Mr. As first. He is a lecturer at the Faculty of Science and Technology ITB since 2000 since 2018 until now. With an educational background of ee since S1 single S3 completed his education at Bandung Technology. Then the research, eh scope itself, is structural biology with mitigation of eh natural disasters using eh geomorphological methods, remoteness and also geophysical surveys to map eh active fault zones, eh land subsidence and also analysis of eh diversity like that. I invite Mr. Astika to present his presentation, Miss. Okay, thank you Mas Faiz. Hey, wait a minute, I'll share my screen first. Good. Ee so on this occasion ee I can try to give what maybe ee a little ee background from the tectonic side then also ee from some ee geophysical data and also ee bathymetry in the ee ee study area in the area where ee experienced a fairly large earthquake yesterday. Hey, wait a minute, where is this? Okay. Well, maybe in a little outline in general, okay? It has been explained earlier, but maybe I won't elaborate, just a little at a glance. Then, regarding the several earthquakes that occurred, and the source of the earthquake on August 15, 2026, if we look at the existing data, what was it actually like? So, then how is it formed? So why do we have such a long back-bow fault? Even though it was actually conveyed earlier by Mas Kadek and also Mas Dimas. Okay. Eh, from a regional tectonic perspective, Eastern Indonesia is actually a very complex area. So, it's not just the Flores area, but almost all of Eastern Indonesia, which is a complex area and geologically quite interesting. Very interesting. ee even some time ago in 2021 there was an earthquake there , right in the middle of here, ee we were surprised because ee previously we didn't expect there to be an earthquake there and it turned out to be quite big. Well, ee then we had an earthquake ee a few days ago ee west of the earthquake that actually happened before. So, if we look at this ee, there is ee flores trust, right? Then to the east it is usually called eh wetar trust. ee electronically this is quite ee complex because we have eh the Australian plate which is moving north, then there is Eurasia which is eh relatively eh still like that. But there is another one, the Caroline eh plate or Pacific Plate which goes west. Well, those three then became one in eastern Indonesia, right? uh, one of them, uh, we then had the Wataras Flores Trust all the way to Bali, that's how it was . Well, tectonically, the Flores area should actually be a volcanic arc and the north should be part of the continental edge, or Sundaland. But later, we'll see, it was mentioned earlier that we have a very deep sea, even more than 4 km, almost the same as the one in the south of Sumba, right? ee in terms of GPS if we look at ee what is the velocity in terms of ee relative to the block, for example ee in the East then ee from Flores Sumba to the east, this is actually basically ee relative to heading north, almost the same as Australia, right? although it's true that Australia is ee faster because we have shortening in ee in Morf Truspeld or eh all the way to Tanimbar, right? Well, ee later we will see if we look here we have Florest which is heading north, it is quite good, maybe 2523 was mentioned earlier, but we see in ee Sulawesi it is relatively small. This means we have to have a shortening between Flores and Sulawesi, right? Well, later one thing that is quite interesting is actually, eh, we have the Calautoa fault which turns out to be a strike slip but eh, east-west, right? Well, ee as a result of that then we have quite a lot of earthquakes. So, most of the earthquakes are in Eastern Indonesia. If in Indonesia, ee, from north to south, if in Eastern Indonesia, it's full like that, right? Well, ee, there were several fairly large earthquakes near the location yesterday, ee, we had this earthquake, ee, maybe in 1900 here, we had one in Maumere, eh, in Fest, right? This is in ee petar, in alor like that. There are several of them whose magnitude is above seven, right? Eh, it was also said earlier, so ee an earthquake above seven in this area is actually not something that ee strange, right? So it's very common, it turns out. we have a lot of history. Ee if we look at it side by side for example, what happened yesterday was ee 7.7 with a depth of about 15 kilo ee previously in 1992 we had 7.8. So ee it's a little different 78 7.9 like that. Well, while in the north we have what I mentioned earlier, this is a strike slip with a magnitude of 7.4. Well, ee, what's interesting is actually this part. This is a fairly deep sea but it turns out it's not that quiet. So it turns out there are several shallow earthquakes that are to the north of this fault. Later we'll see what it's really like, okay? ee, maybe I don't know either . But basically, an earthquake of 7 point something or something in this area is something that has not even happened in the last 100 years, it has happened several times. Hey, if we look at ee, so there are some Florestas that might even depict the continuity, like fellow backtras, we also have that in Java, right? but in terms of activity or shortening rate, it must be very different, right? Because if we look here, the difference between Sulawesi and Flores to Watar is something that is quite different, right? So the shortening might be quite good. Well, there have been quite a lot of earthquakes, as mentioned earlier, there are ee in Sumbawa, Lombok, and then Bali, which have experienced quite large earthquakes. Then if we look, well, in the south, as was also mentioned earlier, it is very different if we look at the south of Lombok compared to what is in the south of Flores, or in the south of Wetar . South of Flores we have Sumba, we have the East Island which also has a lot of earthquakes but morphologically they are very different. Well, then we'll see the earthquake that occurred on August 15th. So, on August 15th, we had an earthquake that, in terms of mechanism, was almost the same as the earthquakes that occur behind the arc. So we have a big earthquake going up ee mostly from up to Bali ee Lombok e Bali like that yeah. This is a lot ee a little different from the one in the south. In the south we have quite a lot of normal faults. Well, eh, this is precisely what then, if we look at this type, I suspect that this is what happened in the north or that after the shock after the shock, maybe that could be what happened . ee ee typical like this. But later we'll see what it looks like . So if we look at this vocal mechanism, eh, the section to the west of the earthquake that occurred yesterday. If we look at this cluster, it is a cluster that has nothing to do with the subducted plate, right? Ee, even though this ee has gone down, it is very far away at a fairly shallow depth. So if we look at it regionally , from west to east we have quite a lot of these collections . The further east we go, the more we see it, to the north and east we have a lot of them, and most of them are thrust faults . Some may be normal cesareans and some may be stip cesareans. J if we look at this it is very consistent. We have quite a lot of ST slip, ee, there are quite a lot of ST slip thrust faults behind this arc . Well, these earthquakes are the ones that, eh, if we look at the association with the fault behind the arc, right? If we look at the cross-section here, that's how it is, in general it's something like this or that. So we have Sumba, we have the East traf in the south ee we have Sarnaik eh Voltrust belt in the East to the west of the east like that yeah . Then there is the Savu Sea, then eh Flores. Well, then we have the Flores Spect Trust or Florest trust or wetar trust behind it to the east. Well, then we have the Selayar Islands, right? So if this is Selayar Island, while the one to the west and east is the Selayar Islands. Well, the Selayar Islands are separated from Flores by a fairly deep sea, even deeper than the East. It's more than 4 kilos deep and it's quite narrow . If you look at it, it's just like that . Well, due to the earthquake in 2021, we learned that the Selayar Islands are actually a strike slip. Eh eh the result of the strike slip which then emerged as small islands ee including Kalotoa Island which is on the east side ee, right, close to the source of the 2021 earthquake. But yesterday's earthquake eh mostly should have been in this part. So in the north of Flores Island, the shape is ee PKAS. Well, if we look at this area, there might be some seic data that we compiled, this is from silver, it's actually quite old. So ee even before the 1992 earthquake ee was acquired in year 1 if I'm not mistaken. So it's clear that we have these thrust faults at the ends. This one is even almost 4 kilos deep here and this one here is more than 4 kilos. Well, then we have ee fault eh strip slip which is in ee row of Selayar Island earlier. This is to the east of this area where we experienced the earthquake in 2000 or 1992. So it might be true that besides having a rapture which might be on the front fault or the frontal fault, we might have a landslight, so then the earthquake could be very local. Hey, this is a bit more to the west, yeah, it's almost the same. So we have a thrust fault that is steeper, more upright on the south side. Then to the west, ee, to the north, we have an imbricate fault, which then ee has a decollement a bit further from the large fault, or a more vertical fault, right? Ee this is the other one ee on the side closest to the earthquake that occurred on ee August 15th yesterday ee the typical is the same. So we have this one, ee, how deep is this? 6.7 seconds. So maybe 5 kilos or so? Ee maybe 5 kilos ee 4 something up to 5 kilos. Hey, we have a sediment that if we look at it, we can see its characteristics, it is something that is flat. Actually, we will see some examples later. But then when we emerge, we see that there are folds on the north side, that's right. This is to the right in the north. Well, this ee then connects or connects to become one with the ee fault in the more upright ee to the south. N the earthquake itself will definitely be lower down. So there is nothing in this ee seic. So if we zoom in, maybe this seik area is only a small part at the end, right? Meanwhile, the main earthquake was there. Well, ee, even so, ee earlier, the rapture could be the same, ee, it could be there, it could be in front of that, right? Well, this is what might also differentiate the tsunami, right? Is the rupture here or is the rupture ee from there entering the decollement to the area at the very end or at the frontal fault. Well, this might be a topic for further discussion, right? Um. Well, actually another interesting thing is when we look at the after shock earlier, there were many after shocks that were ee located north of the ee line ee from the ee line drawn from Pusgen, for example. Em, it's a coincidence that Pusgen ee drew this fault without using multibeam data or bathymetric data that is quite detailed, right? Eh, so the e that is taken must be the ee area where the slope is clear, right? The distance between the LED and the ee is quite steep. So ee will definitely be there. Ee, but it could be that then we have ee in the future like that. Ee maybe the after shock is there. But then the question is, if we look at the depth, the after shock is actually much deeper, right? So, do we then have a mechanism like this, like what happened in the south of Sumba, for example, we have a normal fault in the subducted plate. Well, ee it could be like that, ee, it's also related because we have a very deep sea, even though it's shaped like that, huh? Well, is this it? Ee then earlier, if we look at the vocal mechanism, it also has normal faults like that. Well, this becomes a hypothetical ee or a question whether it is possible for us to have a normal ee that is in the lower ee of the decollment. ee if from ee from ee geology like that, ee from geological structure we have ee things like this are very ee common, ee for example in the south of Papua and then in Seram like that, right. Hey, we have the Voltras belt above, but below it, we have a normal fault, right? Well, but is it then active in ee at the same time? Well, that's something we need to look at in more detail. Ee so if we look at it earlier, yes, this is south of Sumba, this is Sumba, this is Florest and this is quite deep, yes. That was quite deep . If we look at this bathymetry, the bathymetry is quite deep, ee more than 5 eh 4 kilos earlier, right? ee this is an earthquake in 2021. Well, ee let's try to see one of the bathymetry ee which is quite detailed for the area that ee Flores continues. So if we look at this, this ee was acquired in 2021, coincidentally with Baruna Jaya's ship, Brin's ship, right? Well, if we look at the typical one, it's actually like this. So these are the folds in the area that is more at the front, this is the frontal area . Meanwhile, we have a fault that is quite steep, it is behind here. It could be even further back but usually it is this one. But we can have it in front of ee which is quite far away, yeah. Well, this is the area that, ee, if we look at the seismic earlier, ee, the sediment is quite ee, flat, right? Well, ee this is what we then need to ee see whether ee produces a different tsunami when the rapture is over there, yeah. Ee, compared to if the rapture was over here, right? Well, this could be the difference ee in the height of the tsunami, it could be from there or ee there was a landslide which is also very possible because this is quite high . Okay. Ee well, that's from some of the data that we can see. So if we look at it tectonically, basically the area we see today in Wetar or in Flores to maybe Sumbawa, the eastern part is a little bit different from what we see in Bali or Lombok. Well, why is that? Because we have ee eastern row ee tanimbar like that. Ee rote timur tanimbar. Sumba is a bit of an enigma when it comes to geology, right? Because geologically, many of these are more suitable for Sunda Land, but ee, it is already south of Ar, right? Well, this is still a question that requires a lot of effort to answer. Well, that's about it . So we have ee wetar which is here, wetar teras ee there is a row of banda ark, then we have timur which is in the south. Well, in the south, so if we look in the southeast, it's actually already a continental margin, right? So it's not like it's oceanic anymore. Well, it's something like this. Ee so if we look at the volcanic arc then we have ee florestras. So, is this florestra deep enough to initiate an arc reversal? Well, that becomes a question like that. Em, whereas if ee in the south east is no longer subduction, that has also been conveyed earlier, right? So we have a collision so that ee can be then ee ark becomes reversed like that. Well, so if we look at the history, uh, tectonically, maybe the start, uh, the start of the collision, some say, was 25 million years ago at the earliest, uh, that's it. Or there are even those who say that ee 5, 5 million years ago, it just started. But it's something like this, yeah. So ee this is ee row of Flores and Wetar. Then today it was like that, ee, the earthquake that happened some time ago, then many of the 7 point something earthquakes were actually in this area. So, will there be a reversal then and it will be subducted to the south and then form a new AK like that? ee maybe in the next ee 1 million years ee we don't know. Ee okay that's probably all I can say with the time that ee has been more than 15 minutes apparently. Good. Ee so basically ee Flores Flores earthquake ee is not something ee what is it called? That's strange, isn't it? Because we have quite a lot of historical earthquakes . Well, and the mechanism is almost the same except that previously, the kalouto was a little different. Ee basically in the north ee banda arc the pattern is the same. Then this ee the segment is different, right? So in 1992, from the east, ee, to the west, even though the hypocenters were close together, one was to the east, the other was spreading to the west, as ee Kadek said earlier, right? Then, eh, tectonically, we definitely have a relationship between the Banda Arc and Australia, eh, coalition, right? Will it then become a subduction arc reversal that becomes southern or not? Well, that's what we see. Ee ee okay as a closing ee this is probably the part that ee I often always convey. So, if we look at it from a natural phenomenon perspective, it is actually a geological hazard. A geological hazard is something that will definitely happen and repeat itself. But we are the ones who determine whether the incident becomes a disaster or not . That's all from me. Thank you Pakis. I return it. Okay, thank you Mr. ST for your presentation so that we can complete the discussion, eh, the initial analysis related to the Flores GPAL from various aspects, both from geophysics, geology, and also from Samiars. Okay, after this, eh, we'll enter the discussion session, maybe we have about ee 10 15 minutes left for the discussion session. I invite participants who want to ask questions, you can do so via Risen or I can also read them via the chat column, perhaps. Earlier, I saw a question in the chat column from Mr. AD Suryaputra. Would you like to resubmit it so that the participants can also know, sir? A question that perhaps came too late . Yes Hey, maybe I'm repeating it because I might have permission to share it, Mas Faiz. Yes, please still do. Yes, actually, I asked earlier because I saw Mas Dimas' presentation and then Mas Kadek's presentation, I found two unique things. First, from Mas Dimas' presentation, I saw cluster 3. From his presentation, the results of the HDB Scam in cluster 3 showed a very strong increase in systemicity from the 20th to the 21st, and it was quite massive. Well, then from the results, Mas Kadek also mentioned, well, to the west of the main rapture, which was initially lateral in nature, there was a stopping point to the west, which was near the third cluster, which was associated with the accumulation of stress and aftershock. So I asked earlier on ee regarding those two things. Can we use the time lag between the main rapture and the increase in cluster 3 to distinguish whether cluster 3 is a direct response to the concentration of stress around the stopping point or whether it is merely a triggering from a fault segment that is different from the main segment of the fold itself. But earlier, and it's interesting, Mr. Astika also added something related to the indication that there might be an imbrace there, Sir, as a result of, uh, maybe there was a landslide because of the very high difference in that area, Ma'am, eh, maybe that's the battery. Well, thank you Mas Sti, eh to Mas Dimas, perhaps I would like to elaborate on the latif response answer. Yes Okay, ee maybe I'll complete it. Thank you, Mr. Ade. Hey, I also have n't emphasized that clusters 2 and 3 actually had a kind of delay before they were activated, around a few hours after the main earthquake of magnitude 7.7, between 12 hours and 24 hours. Well, this delay triggering is also interesting, because in some cases, delay triggering may be related to fluid redistribution or, for example, other mechanisms that are interesting to study from the stress triggering framework. Maybe that's from me adding. Then why did he ee increase again significantly on August 20 and 21. Well, this mechanism also needs to be explained . So I think there are a lot of interesting things in this sequence. Thank You. Okay, thank you, Mr. Dimis. Mas Kik, maybe there is an additional check. Ee maybe if I add it, eh, it seems that if we look at dynamic stress, dynamic stress is an instant triggering that is behind the S wave or surface wave. Well, will this dynamic stress transfer increase or change the stress conditions in the area around there or not? Well, that requires a more in-depth study, right? Are there any indications of small earthquakes in the wave code? Well, that's what you need to look for again. Well, ee maybe if for example ee from his sensitivity ee is a bit longer , maybe ee is more inclined to static stress eh transfer, but will that static stress later activate ee new mechanisms around there that need ee to be researched further like that. Okay, thank you sir. Eh, maybe I'll also invite Mr. Rubek in case he has any questions regarding your presentation . Thank you, Mr. Faiz. Hey, this presentation is very interesting, complete from various scientific disciplines. Earlier, I had the chance to observe what Mas Adit and also ee Mas Kadek said, regarding the comparison of the earthquake and tsunami incidents in 1992 with 2026. If I try to look at the results of observations eh USGS both in 2026 and also ee 1992, the definite fold slip is quite different, ee the dimensions between 92 and 2026 where the pedit fall slip in 2026 is spread to the west and the dimensions are very large, very wide, yes, compared to 92 which is more to the east, eh finite fold slip and its dimensions are also ee maybe almost half of 2026 with a magnitude that is not much different. So, are there any geological conditions or explanations that can provide an understanding of why the tsunami that occurred in 2026 was so different from that of 992? Is it because of the influence of the finite fault or is it because of the influence of its morphology? That's all, Mas Faiz. Hello. is there any here? There is still a committee to answer regarding the differences in tsunami characteristics or perhaps there is something related to that, sir. Oh yeah, maybe you need to practice it, bro. So, maybe Mas Adit should be able to answer this in more detail because I was also curious earlier about the rapture in the area, what is it called, which is already quite flat, or the column is sloping or quite steep, is there a difference in terms of the tsunami? Because if we look at the slip ee fault model, it tends to be the upright ones, or the steep ones. Meanwhile, if we look at the small ones, they tend to be in rocks that are eh, maybe sedimentary or not, eh, not crystalline rocks, which is why there probably should n't be an earthquake because from the surface it might not be that deep. If we look at Colmen, maybe it's only a few, maybe 1 kilo or so . There shouldn't be any artifacts like that. But ee if he slips past the one in Colmen, then ee what is it called? The tsunami was probably much smaller. This is this. Well, I'll add a little, maybe an addition, I just remembered this, if I'm not mistaken, Mas Kadek said that earlier. So if you experience changes in ee strain or changes in ee stress, the ee that is affected is actually in the north. Well, this is what ee if we look at ee if the earthquake is already ee 2021 like that. Meanwhile, if the loudspeaker is actually connected to Selayar and then the one in Sulawesi, right? So, can that also be a trigger or, for example, stress also has an effect because, if I'm not mistaken, it's been quite a long time since there was an earthquake and it turns out that if we look at history, there have been earthquakes, maybe around seven or so. So, can it then go far enough to Selayar and the north of Selayar? ee Walah nae is that possible? Maybe ee how come Mas Kadek, I ended up asking that. So, Mas Tiko, I saw that the 2026 earthquake, eh, the concentration of the slip was only around 2 meters. But if it's 9, if it's 2026, it's 20 m. Sorry the 996 is only 2 m. So there is almost a 10- fold difference in the dimensions of the ee slip, right, between the 2026 and 1996. Hm. Ee I might want to add to the discussion ee if for example ee ee earlier ee ee Mr. Ruben ee what is the question why is the slip a bit different? The first one is maybe ee we can see ee the difference in data resolution yeah. For example, if I saw what was presented by Mr. Adityya Gusman through what is called the publication from Mr. Rian, I saw that there were two large asperites, there were two large slip areas and if compared to yesterday's Flores, they were somewhat distributed. Well, this needs to be accessed using ee, what's it called, dataform, right? Is ee really stressed ee drop or what is it called ee eh radiated energy is bigger or not ee ee bigger than 92 or ee smaller than now. it needs to be accessed maybe ee why it can generate much greater energy even though ee the patch is ee simpler like that. Maybe if the implications for the tsunami are there, then in my personal opinion, I would rather see whether the slip actually reaches the surface or not. Em like that, eh Mr. Ruben, maybe later eh Mr. Adit can answer more eh comprehensively why eh the 92 earthquake produced a much bigger tsunami. Okay, thank you, sir. Okay, since Mr. Adit is here, Mr. Ruben can ask Mr. Adit another question. Yes, Mr. Adit. Bro Adit, I'm a bit curious, why is it that with a magnitude that is not much different, but the impact of the tsunami in the 2026 Flores earthquake is very different from 1992. Well, from Rian's paper and also the results of the USGS finite fault slip that occurred last week's earthquake, I saw that there was a very different distribution of slip in the 2026 earthquake, it was only around 2 m, but if the distribution in 1926 was 20 m, while for 1992 it was more concentrated at 2 m. Is that what caused the tsunami to be insignificant because the distribution was more even like that. Well, this is an interesting question, isn't it? So actually I can't answer in more detail because the analysis I did is still superficial, it's still like a simulation using global mathematical data, right? Emm then my measurement data is also not complete yet. As Mas Dimas has said earlier , there is new data that was measured by the BMKG field team that needs to be entered. But yes, consider what em ee what yes, the initial estimate is that maybe because ee maybe the slip is there are several slips on land then maybe there is a combination of locations ee the location of the slip is also maybe because em the large displacement is the vertical displacement is in ee shallow waters maybe em so the amplification is less ee optimal like that . So the tsunami wasn't too big either. it could be like that. Tap ee, it needs to be done further analysis , but in my opinion, what needs to be prepared is the data first, ee, the quality is good, then we can simulate it with the results, what are we confident with the results, then we can draw conclusions. For example, right now I can't talk much, and the simulation also requires both. 1992 was simulated again and 2026 was also simulated again. Because frankly, the data for that area is not yet complete. Maybe if there is, maybe I should communicate with Mas Rian. What bathymetric data does he use for his simulation? I collaborated with him so that the results would be more reliable, then I could give a more complete answer, bro. Yes Thank you. Thank you. That's Mr. Tadit. Come on. Good. Good. Thank You. Ee for the question. Perhaps I'll give one more questioner a chance before we close the webinar this afternoon. If not, can I ask again, Kang Faiz? Oh, yes, please. Please. Ee I'm also curious because according to Pusgen data, the source of the Flores B atras earthquake has a recurrence period of 200 years, more or less like that. But yesterday's incident was only about 34 years after the last incident in 1992. Is there an explanation for that, from the geodesy side, or from the geology or geophysics side, Mr. Faiz, maybe Mr. Kadek and Mr. Dimas have already said that the location is different, sir. The 1992 one has a different segment than the 2002 one. Okay. Okay. The difference in segmentation from Florest back trust means yes. Yes, indeed, they are both backed by trust. Ee, but if we look at the geography of 2026, it might be north of Manggarai and N. If the 1992 one was offshore, it was Momer. I don't know what district that is . To the east. East of the 2026 event. Earlier, maybe Mr. Mas Kadek or Mas Dimas could talk more about what I wanted to add from Mas Adit. If you look at the distribution of the slip, eh Mr. Rupen, for example, the 2006 26, ee, it spreads towards the west, ee, west, from the 92nd segment, from the resolution, ee Masrian, it goes towards the east. So maybe it's one fault series but in different segments or maybe in different areas, like the western area and the eastern area. Haha. Okay. Okay. Yes, thanks for the explanation, Mas Kadek, Kang Adit. Good. Oh, thank you. Maybe that question will be the closing for today's webinar. Once again, on behalf of HAGI, I apologize for the limitations of today's activities. Ee, hopefully we can watch the recording from Zoom this time together via your YouTube stuff. I would also like to thank the presenters, e Mr. Kad, Mr. Dimas, Sir, and also Mr. Adity Gusman for their very comprehensive presentations, even though the time was quite limited, they were able to explain something, yes, we should appreciate that, ee. Hopefully the final results of this research can be published soon , so that they can be read by various groups so that we can also learn from this earthquake, which perhaps some of the studies considered quite predictable, perhaps this would happen. but maybe there are also some who are quite surprised regarding the dynamics of the source . So we also need to arrange these puzzles so that they become a complete story, perhaps something like that. OK, representing H again uh I'm closing uh the webinar today. Good afternoon. Asalamualaikum warahmatullahi wabarakatuh. Peace be upon you. Thank you to all of you. Thank you, Mr. Dimas. Oh, yes , sir. Thank you all, thank you, Mr. Pres. Thank you very much. Oh, Mr. President.
