tv Tsunamis Deutsche Welle December 27, 2024 10:15am-11:01am CET
10:15 am
i by his wife and 3 daughters. you're all watching dw news up next. we've got a documentary film for you looking at how to protect against tsunamis. i'm terry martin. thanks for watching. the my name is the calls back. said loud. thank you so much for joining in. welcome to don't hold bad. a lot of people do that. it's all about saying it aloud. next, would it be nosy bay? like good, everyone to king. check out the award winning called, called the called back the sonoma, these deadly waves that can destroy a city in a mattress of moments until the 26th of december,
10:16 am
2004 very little was known about them. but on that day it can take 2 nami killed, 230000 people in the indian ocean, filmed on mobile phones. images of the phenomenon were beamed around the world. 7 years later, in 2011 and u. k. a pallet pound to exploded, of to being engulfed by tsunami. and focusing much upon the weight of these tragedies, scientists have been improving the knowledge of these devastating ways to save lives in the future. understanding them is the essential we know that saddam is kind of could, in any region of the planets and coastal development makes everyone increasingly vulnerable. can new scientific developments protect us
10:17 am
the the friday, the 28th of september 2018. the indonesian island of sula, wasting a tsunami trigger, that's fine as quick in updates at the bay of pollute within minutes. full 1000 people lost their lives and 79000. others had to be evacuated. how could a tragedy like this happened again the to find out, eunice, go and the indonesian will, sorry. he's brought into tsunami specialists,
10:18 am
profess it cost us. and it like is of the university of southern california and professor him and fritz of the georgia institute of technology. quite impressive to see the devastation there now 3 weeks after the event year, we can try to see why it's important to come up as quickly as possible, or at least once the emergencies over because a lot of bulldozing in this area already. so a lot of evidence is very last for that is, you know how to look for them. this wasteland holds valuable clues but time is running out the monsoon rains on the way. the worst thing is there. so normally scientists is very much like being a detective when a crime scene, there's a multiple murders you really have to piece. i can think of possible the
10:19 am
sequence of events. data to nami, shift 1st, at least maybe the houses collapse or wherever they collapse because of the earthquake and resume. now, i mean finished them. what were the people doing? why is it that some people die? and some people develop those investigators as one to understand how the dissolves to unfold it. they go to trace the tsunami, back to the original event that triggered the ways in the small fishing town of wanting cost us and the like his goes to meet some of the survivors. abdullatif is one of them. when the wave hit, he was on his bows, $100.00 maces off shore. at the time of the 1st way. if when there was a big trend, i went out on the deck of the boat. did you feel the tremors long?
10:20 am
yes, the boat shook because the water had gone down and the boat was ground, it took up on what it could do as long as she stayed with the boat. the of the what you style about. but do you want to define these in front of them? i was holding onto the multiple pick them. yeah. oh okay, cool. yeah, forgot to sign up. i go back and then i saw the way of breaking on the distance. it was very fast in no time at all. it was next to the boat pushing a 2nd about room. i got on file about how hard was it. i had time to see my house. the top of it was almost the same price as the boys have groups to guide the where is your house or the then that's the way it was about 5 to 6 maces high, the height of my house and didn't have to go to my so cost us in and out because it's a mystery when it by like this is usually protected from konami's. how did a 5 me 2 ways get this phone
10:21 am
trying to get how much is south of wanting human freights as conducting research in the town of polluted with thousands of people died the accompanied by 2 indonesian scientists, him and fritz goes to the parking lot of the shopping mo, evidently the baby. to better understand the dynamics of the waves, the consults, cell phone footage, taken at the time of the disaster. this is the exact spot that we saw on the fee do . so you can see the billboard years and all the way from people running away, people are running away. and that's the 2nd with secondary way located. now we can basically see how high the water is almost inside the billboard
10:22 am
g, or the wave was move in full meters high the to a den to find the source of the tsunami. and then fritz needs to create some model of the devastating wave by determining its height at different points in the city, and measuring how far it spread. and i tried to some details survey news. if you're going to try to get a full 3 d stats, and the purpose of that is if you do a 3 d space base, the light stands all the points last time you can see how the weight goes through a ticket and measure how high the wave is of every given incidence and how fast the wave is moving across is through the house as washing away the houses and across
10:23 am
the street. after 3 days of field work, the 2 american researchers and their indonesian colleagues of finally able to reduce a 1st simulation of the tanami that's of much the by of probably going to the observations, the most powerful wave spread more than 300 meters and bought for cost us in, in august and him and fritz. this is just the stones. the next step is to identify the event that triggered the steady wave and to determine how it was able to reach the bank. the so means the polt and nami means the waves. the waves that destroy the co, which this would now universal dates from the 17th century. it comes from another place on the planet most frequently hit by tsunamis,
10:24 am
japan it was coined by fishermen who retained on the storm free day to discover they pulled had been devastated by waves. the most recent phenomena in japan in 2011 caused a new to accident in focus, fema following a 9 point one magnitude s like this wave claims the lives of 18000 people. i mean, not a so no, i mean it has no mediator a logical cause cause it's in the primary concepts. anomalies are earthquakes, minimal increase at the same most sonoma is that generated by all planets to tonic activity. the crust consists of several launch sites. maxima pushes them against one another, a few, many meters to a few centimeters, a yeah. the actually on
10:25 am
a close like the nice, the continental plates foaming subduction, sens friction between these mass of slabs of rock causes continental plates, deformation, and was it a launch build up of energy? when the stress is released, it generates a huge and to see of quite comfortable they are, it's quick displace is all the water at once and assume that kept keep them in. so for 4 kilometers deep, we have 4000 meters of water that moves up to speed up in airliner. very quickly as we approach the coastal, the speed is reduced, the wave gets bigger. so can we find ourselves on the coast with waves of 20 to 30 meters as we saw in 2011? i could do a complimentary come up as well. all the meanings the
10:26 am
we cannot separate earthquake signs and cannot assign longer duration of yours. great, very good. indication of how strong it's basically, it's like a zipper. if you have a smaller it's greg. it's a short rupture area. and that means the duration is sure. if it's a bigger, it's craig live, sumatra $90.00 to $9.00 or japan mag a to 9 plus events. and base, if you have a very long zipper that means the shaking will go on for several minutes. changes across the the longer and more intensely under c s click, the more powerful the tsunami. and that's precisely what happened on the 26th of december, 2004 in the indian ocean. 100 kilometer is off the coast of bundle
10:27 am
shea. on the indonesian island of sumatra, an earthquake rough to default line measuring 1200 kilometers. the 9 point one magnitude of quick last it for more than 5 minutes. 15 minutes later, 35 meter waves hit the coast as it continues across the entire indian ocean bits. unami ultimately claimed approximately 230000 lives. a token lipstick seems captured live by hundreds of cellphone cameras. the revealed the devastating power of these deadly waves to the world. previously, little was known about the phenomena. the event was also
10:28 am
a wakeup call for to nami science, which advanced considerably in the wake of this natural disaster. the the of the numerous international studies launched and research by indonesian geologist nicely is male led to major revelation the 8th. as soon i may reach 30 meters high, up to the top of the hill over there, rushed to the mountains, but very few survived. the thing because for clues left behind by the tsunami, natalie is now made an exceptional discovery. first it can nominate yourself
10:29 am
a bundle, a che obviously, so the off to the 2000 and policy and i mean this case was full of debris piece. is it, would it be one moment to be been pissed down? so i'm going to, these kind of has a very particular architecture that it is l shaped and it's entrances, power allowance of the kind of want to but how about funding? so every time the want to, i've assumed i'm a, comes to submerge these cave. i you will not be it is retained inside. yeah. the problem that i'm looking at the family by law natalie as well, had a hunch. if this cave trapped the material carried by the 2004 to nami,
10:30 am
it could also have stored evidence from tough catastrophes. the cave had another particularity that the colonized in form and then the, the pattern so not interested in ami is covered by a lab gone on. i thought it was to pull it up based on what i know about this. you can see the layers of guano in black. he has so many times, but they need over the years, the layers of guano, or that droppings deposited between each tanami 1st to nice to form a t, a boundary delineation each separate event. this allows to nami, then a lot of quantum or they have to nami animal quantity, then as soon ami, then mol guano. so now me think one of the 2000 and focusing on me a
10:31 am
total of 12. so nami deposits make up this settlement of and i with the help of researches from single pose. it's observatory nicely is male is able to date the 12 deposits by carbon 14, as they tell the story of the tsunamis in this region over the last 10000 years. the author deposit corresponds to the 2014 nami. the next event as about 2900 years and then photo nomics, the code 25 years, a pause about 3300 years ago. the oldest was about 7500 years ago. not very come on from the data obtained here. we have discovered that to nama is recovering irregularly. this debbie, i'm assuming about the, the, the this is the lesson for both the government and the people
10:32 am
that we have to be vigilant to be constantly ready because space disaster can happen at any time on this exceptional discovering is a game changer. now scientists know that where it's a nami has struck one another, can strike again the now the question is, where have to nom has occurred in the past. the 1st 2008 unesco has maintained a world wide tsunami. met updated with scientists. nicest discoveries. 1200 sonata, these have been confirmed of the costs, 3000000 in the least destructive,
10:33 am
unlocked in light and the most deadly in rent. that's a non, it can occur anywhere and could potentially strike the same place again around 70 percent of tanami. so located along the pacific bring a fine way subduction zones all have the concentrated, but they have also could in other areas, especially in one region now considered safe from this kind of disaster. the mediterranean, the nice thousands of tourists enjoy the pleasures of the beach. but not far away, a team of scientists from the g u. a zoo or the bar tree is trying to determine the cause of the cost and dissolves to
10:34 am
trolling through local archives. researches discovered that on the 23rd of february, 1887, a section of french and italian coastline was hit by a to me so hard to nami wave treated by an i'm just see us quite from nice to general. at least 600 people died on tens of thousands lost their homes. today, vieira is home to, to 1000000 people to the seminary event occur again. of the, do you, as a research team is working to locate the folks that calls the 1887 of quake and the says it's condition to see what is it that you're going to battalion scientists. and the times, however many under mccully recorded in a very precise way, full the destruction that happened on the coast to records. and we have 2700 ohms of ation points between friends and recently.
10:35 am
christopher, how can and his team use these types of graphs taken at the time of the designs to, to map the quakes intensity the most significant damage, the close of the souls which was located off the coast of the italian city of imperial. but identifying the precise felt responsible for the 2 nami is a dedicated task of tools. the size makes zone is one of the most complex in the world to the african plate. and the sauce rises to bullets, the raising plates. and the news pushing corsica and sardine against the riviera, generating numerous seismic phones is
10:36 am
identifying the fault that calls the $1887.00. so nami, even possible, is uh at the end we using sophisticated size making investigation equipment, essentially canada, so used to create waves. these will allow us to obtain a sonogram and being assigned to be up to 15 kilometers deep and the waves will be recorded by the senses we have within the line of the line. that's 6 kilometers long drank behind the boat to of the up to 5 days at sea, the ultra sound reveals not one but 3 phones below the sea film. the location. so security number 2 is from the coast, corresponds to the epi center of the 1887 of quite the. and then we'll follow that to you. of the fault suggests that they are still active and allows the scientists to model 2 possible tsunami scenarios. look forward to
10:37 am
using the you. the 1st scenario isn't a quick equivalent to vast of $1897.00 with a $6.00 magnitude which would break a full length of about 30 kilometers, a wave heights to maces. and the 2nd big screen scenario is to envisage a rupture over almost the entire length of default. for example, 60 to 80 kilometer, which we've been producing is quaint of magnitude 7 and wave heights that include rate 3 to 4 meters whitecaps. we met the mediterranean region among the world's leading tourist destinations. is that the risk? but scientists can't predict when an event like this might have come since 2012, the area has been monitored. 247 by the tsunami warning centers sent out evacuation
10:38 am
chance had been drawn up with a focus on nice. but one thing remains trees. a rupture of the thoughts so she can nominate his from the coast only in those 20 minutes of these occupation time before the waist breaks. not even a small so no, i mean it can be really devastating. the wave breaking on the beach with the speed of around 40 kilometers per hour will create extremely strong currents. the people come swimming on these on the spot nations. maybe the rainier and beach is just like many beaches in the indian ocean, are very highlands. there is, or is that in the summer week, i'm a 5 tens of thousands of between easy. there's one of each wave of possibility over some, not me arriving, you know, within a few minutes, coastlines are popular with locals and tourists all over the world. this makes
10:39 am
tsunami warning systems. mold them all necessary impulse new where it cost us interlock his and him and for its continue their investigation. a tsunami warning system was set up off to the tragedy of 2004. so we're only where there's still so many victims. 15 years later there are lots of food vendors right here. a lot of people that, i mean there was a run. those are like this. people were shouting all over the place. the bolt is rising. the want is rising up, i, i this witness says people here, but completely taken by surprise. no way that the reach this area, the, the investigation continues at the tanami monitoring center in the indonesian capital chicata. this control tower monitor seismic activity throughout
10:40 am
indonesia, including the bay of palm, new a few slides monitors can detect any escalade, etc. in real time advanced algorithms allow them to send me the information of a tsunami and one people before the 1st wave hits. since the systems implementation in 2008, 22 and that's have been issued and countless lives have been saved. then why wasn't they were boning received in pollute on the 28th of september 2018 plus monitors. key on putting us think he was on duty that night on the, at the time of the earthquake and tell who the magnitude was. 7 for 2 minutes. and then just afterwards i'm on the magnitude rose to 7.7. that was when i ran to the,
10:41 am
to the west table, which is the so now me simulation table links when i mean in the early evening, and as quick as he can. number 2 is north of the bay was cleared it detected by the casa for the epi center is here, paul, who is there? the simulations assessment was that the escalade presented only a moderate tsunami risk. nevertheless, and the load was triggered within the prescribed time limits. 5 minutes off to the quick so what happened the to answer that question cost us and a lot, cuz consult cctv footage. on friday,
10:42 am
september 28th 6 o 2 pm. the us greg hits the bay of police. the trim is lost a little over a minute. the the quick feel like wasn't really unbelievable. you couldn't stand on the impossible. i was there under the camera to i was hanging onto the gate, then it come down and i came out to be crossed his mind to austin real quick because he's so close to the water. perhaps they've always said to me is a big it doesn't hanson armies that they always are currently open seeing and yet it happens here. a lot of these images provide researches with crucial information on time. the video time stance show that barely 2 minutes elapsed
10:43 am
between the end of the quake. and the onset of the tsunami, the speeds like this had never been recorded before. by the time to content sounded the alarm, the wave had already arrived and destroyed all communication systems in pollute. what is very alarming to me is that sir the earthquake. 3 good. this will not meet very quickly. so we need to understand how this happens. and also, what is the time how quickly after the earthquake hits it's nomic, i'm saying coding to the jakarta center simulation wave. boeing close to the
10:44 am
epicenter. 80 kilometer is north of the base should have taken about 15 minutes to reach, but do not to this tanami defies all known passions . what made this wave so fast? to figure it out, the researches take to the air the let's explain the important how the birds i view this by being up from the allows us to see how this way came in and see the extend of invitation. one of sedation is surprising. the devastation alternates between the unaffected areas. but that's not all. once you get outside of the bay wave disappears very quick. and you're looking at very beautiful indonesian beach. so that already
10:45 am
allows to confine to zone read to look for further for the sources to inside the bag. if the waves that devastated polluted had formed in the ocean, it would have hit the entire coast line. him in fritz and cost us in it like his realize that the epicenter identified by the to cause a warning center couldn't have directly created the kind of waves. the source of the tsunami must have been inside. the bag itself had been fritz and his indonesian colleague, god power set you be 10 to the west and backs of the bay. they want understand how the tsunami could have originated from this sheltered area. gar, power such as connected, new footage films nearby. the body is still over there in position. so then you can see also in the background of these the events and it has been discarded. the font size yeah,
10:46 am
local landslide. great. you have a small semi circular wave that you can even seen the video. yeah. so i think this is going to be a localized the impact and it is land slots. and i mean, you have a lot of eluded material here. so i think once you shake it to him and fritz, the low intensity of this says ways sumed at the very moments of its best suggest it was triggered by a very localized phenomenon, a coastal land slide. here we have evidence because we have a coastal car. ok, so this car actually is along the shore line. the land went into the ocean. and so we have a post landslide. i don't think there's localized and i mean it's big enough to be the main source of it's an army that wiped away follow or. 5 vonny on the other side of the bay. the thing the antonia bay,
10:47 am
researches discovers several others, some of the advance lines, all sources of meaning to nami. but when they look for the internet and the full story of the polluted synonymy is finally revealed. a lot of acid, me looks nice, but that's pretty amazing. what the honda will be, asa where he is. the reason do you have to do? the trim is open ended, then closed it and opened it again a few 100 meters away. a 2nd witness has another a newman, a thing story. so i'm wondering, i mean, it collapsed all the way down, all the way to the most can a cry. all the houses collapsed at the same time from south to know, like the slope of the house. so my of an immense focus on cuts through the town and then extends into the bay for tens of kilometer
10:48 am
researches finally have the onset, it's this fault that close the pollute. so no me after 5 days of field work and months of data analysis, they can find the reconstruct the sequence of events. on the 28th of september 2018 at 6 of 2 p. m. a 7.2 magnitude as quick as because ac columbus is north of police. the epi center correctly identified by the to cause a control center doesn't directly trigger the tsunami. the quake rupture the us out of staggering speed of 14750 kilometers an hour within 2 minutes. this set land slides in motion all along the coast, creating a concentration of minutes and all of these these ways then combine to form a single powerful wave that swept across the city.
10:49 am
the ham and fritz and cost of sending boxes have completed their investigation. the reconstruction of the bay of pollute synonymy will help improve loaning systems all over the world. and we just the think events . so now i'm is only slide can areas where you have some vaccine results. we now know just like one company here that so now i'm just going to slide briefly much any place where you're going to have and that's great. we are very concerned about this because similar earthquakes could take place in seattle. it will take place in southern california, they will take place and they're going to be in big, big placing in the me during the s clinics sold slips. volcanic eruptions, phenomena is, can be triggered by all kinds of tectonic activity. research carried out over the
10:50 am
last 15 years has helped to improve warning systems and visual, adapt them to each risk side in japan, a country at the forefront of tsunami science. the technology is the most at phones did research as know exactly where the next is off. to will arise the this isn't a scene from a disaster movie, but unofficial japanese public service video festival cost in march 2018. it's meant to prepare people for it. so know me. scientists say there's an 80 percent chance that one will occur within the next 30 years. the phone doesn't just offer practical guidelines. it also predicts the most likely scale of the next is almost a $350000.00 victims and wide spread damage that would affect the japanese economy
10:51 am
for at least 20 years to the possible cause. a rupture of the non cod fault that runs along the countries west coast from 900 kilometers. and i mean that's done on k 12. the threat of a non cai trough is very specific boscus because it's located in front of all the economic centers of japan, whether tokyo, your sako 2nd or no, go, yeah, and i go, yeah, all the cities are ongoing, mobile areas, you know, technology can predict and of quake. but japan has an extensive monitoring system in place ready to issue an immediate public warning. it says a matter of listening to the fault of work knowing when it will move and being able to send me along as quickly as possible. and for that we have that in that system, which is just outside of sort of a the 2nd the next system is the most sophisticated seismic detector. in the world. it consists of around 50, under most and many observatories. equipped with precious senses,
10:52 am
size monitors and extend the roommates is installed directly on the phone line. so that means if i listen, i mean would arrive between 3 and 5 minutes. and the 1st cities with waves of 20 to 30 meters, like the wave interest osaka bay and floods, parts of osaka, parts of kobe. and especially all the islands that have been artificially created. can we take sale? depending on the scenarios, we expect waves of 3 to 5 meters, and that will take between 30 and 45 minutes to count sending to determine the most effective evaluation chance and test protective rules. the dissolves to prevention send to appear. so universities stimulates the effects of a non kindful tsunami in a pool. collect why don't we are almost certain that it will be on us. quake with a magnitude of at least $9.00 and that it will cause us who nami ok to walk. we
10:53 am
need so that don't want us professor united see, simulates a wave with a height of 20 meters equal to this of a 6 story building, impacting the city directly facing the non kind of fold in space of seagulls build to reduce the energy of the waves coastal buildings would quickly be submerged under several mesa. so for the pole, simulations, supplemented by vigil bonds. this one divided by professor his eyes, she's team depicts the progression of it. so nami, in tokyo bay, the although it's 5 kilometers from the see, the olympic stadium neighborhood could be hit by a 9 meter high wave simulation. well, simulations are carried out to the time in hazardous locations a need, for example,
10:54 am
a road will be hit by a way very fast. well, so you should not take refuge that you get to this building will have its entrance blocked by the current of the student army. so you should not give that slot this moment that and you get to, i can i to cause the these models enabled kia, so university to creation, into active evacuation time in the event of an adult. and mobile son, application displays ways progression, and identifies the nearest sites. that means, when i do me session, internet notifications will be pushed out to our cell phones. if you're watching tv, you'll have messages displayed on your screen telling you where to shelter with the soviet. what's also trouble finding rooms huge is essential, but limiting the impact of destruction is just as important.
10:55 am
as the 2011 tanami showed ports of very dangerous places to be carried by foss moving bullshit ships can become shy and projectiles. the full professor has she most have from the university of covey, evacuating people quickly, daring, and this is the priority lowest. i'll come on and i hear you and you close up. oh, sancho bay is very busy every day. so and at any given moment, there are 30 to 50 boats sailing there for you that i'm ok. guess i will, that we have no guarantee that in the event of a. so nami, in this situation, and many have never experienced, everyone would keep their cool and that the ships would evacuate one after the other in an orderly fashion that no, i wonder why they like. that's why we're developing an artificial intelligence system, which will allow ships to evacuate from a news or automatically, of course, that will launch it. it will go through a ok. well, saga is the megalopolis of 8000000 inhabitants and the country's 2nd largest
10:56 am
economic center is city build of a time unimed benjamin's below sea level surrounded by hundreds of kilometers of protective walls. the you see if i say old dominion, what happened in 2011 was that the earthquake had weakened. all the structures they switched to part of the walls had fallen with the crate. i think was one of the so known me campbells with our safety mechanisms were no longer effective if you just needed to these up to date. even the most sophisticated technologies con, predict quakes. these artificial islands break same from the sea along with the houses shopping centers and petrochemical industries built here could be destroyed in an instant. in the event, if it dissolves to lock this information campaigns and an effective public response
10:57 am
will be the only way to save lives. the we might think with timing nature, but it is always had the upper hand showing lines have always attracted people, but the rapid immunization of these areas makes us old and move on to the official warning systems all are in place and some parts of the world aside from the us, we should rely on our instincts and our ability to react to natural disasters with common sense. we say this worldwide, if you're near the coast and you feel any kind of ground shaking that floss more than 15 seconds, move away from the beach, the
