00:36The height where we are assuming that ice was broken is about 5200 meters from the sea level and then
00:46the vertical drop of almost 1200 meters and then again the ice might have melted during that drop and then
00:57again it carried several amounts of tons of sediments.
01:02In that low part and then again there was another vertical drops all the way to the rivers which was
01:10about at 3000 meters. So these very high impact, very high speed have caused the melting of the broken ice
01:20and then also carried out the lots of sediments along the way.
01:53Oh shit!
02:13Probably what's actually happened is it's just kept going and it's incorporated all
02:20of the water in the river valley and pushed it out the front kind of almost like a syringe pushing
02:26or plunging it out in front. So you get this kind of all the water that's there being shoved out
02:33front but at the same time as melting the ice and collecting other water and things. So you get this
02:38really hyper concentrated flow of what's kind of like concrete.
02:44Oh shit!
03:25It doesn't take long for them to be
03:27going well over 100km per hour,
03:30sometimes 200km per hour.
03:32And anything in the way gets incorporated into it
03:35and shoved out the front
03:36and they become very powerful.
03:40But, you know, suffice to say,
03:42I have never seen anything like those videos.
03:46I have seen the aftermath
03:49and I've seen, you know, a lot later.
03:52But to, you know, to see what was going on there
03:57and it's just incredible.
04:13We cannot imagine how such a big flood can be
04:18happen without any glacier lakes.
04:22So such a like kind of knowledge
04:26or the understanding that those mechanism
04:28is very rare.
04:30The monitoring systems,
04:32the science we have at
04:34or we are doing now
04:36due to the physical
04:39inaccessibility,
04:40mountains or the resources,
04:43the limiting that like
04:44to better understand
04:45such high mountain reasons.
04:47and at the mean times,
04:49those gap in the understanding
04:51of the mountains,
04:52glaciers and the other things
04:53and making more and more vulnerable
04:56like vulnerable for the many disasters.
05:00societies.
05:12Oh, no.
05:14Oh, no.
05:23I'm going to go.
05:45There will be a hazard of things falling down
05:49and the height of the flow is such that in some cases
05:53there must be tens of metres up the sides of the hill
05:55so a couple of tonne rock falling 10 metres
05:59is a hazard in itself, all the way down 60 kilometres.
06:02So the rescue effort is going to be just a very difficult operation.
06:40Shhh!
06:43Shhh!
06:49Shhh!
06:51Shhh!
06:53Shhh!
06:54Shhh!
06:55Shhh!
06:57Shhh!
07:02We need a lot of communications at the diplomatic or at the government level.
07:08We need to have cooperations and then we need to have a kind of transboundary, G2G relationship
07:16like to share the data among the different countries because disaster does not set any
07:21administrative boundary, right? So disaster may happen anywhere and then it can cause the
07:28damage in the different parts of that basin, not only in the one country, maybe multiple
07:33countries. So, yeah, we have been like advocating this kind of the cooperation, not only between
07:41the scientists, but we do have a lot of cooperation among the scientists, but this kind of the
07:47disaster management need to come through the government.
08:30We're seeing that the ice withdrawal and the melting of the glaciers and the glaciers withdrawing
08:37is exposing the slopes, which then want to fall down. And we're seeing that in many of the
08:44mountains or place. As the permafrost melts, it weakens the rock mass as well. And sometimes
08:54you get big, heavy rainfalls, the atmospheric rivers that we've got that are quite different
08:59in climate change that dump water and that weaken it. So you can't say that climate change
09:06is causing a particular event, but you can say that the frequency is increasing because
09:11those conditions are there and there's usually some other little trigger.
