after the break, as always there's more news on our website that's d w dot com. i'm all municipal stay with us. the name is the calls back. said wow, thank you so much for joining in. welcome to don't hold bad. a lot of people do that. as soon about saying it's loud and mess with it being nosy bay, like get everyone talking to me. check out the award winning called, called the called back the sonoma, these deadly waves that can destroy a city in a mattress moments until the 26th of december,

2004 very little was known about them. but on that day it's like guns. it's a 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 waves. the to save lines in the future. understanding them is the essential we know that saddam is kind of cut in any region of the planets and coastal development makes everyone increasing evo of all. can new scientific developments protect us

the the friday, the 28th of september 2018. the indonesian island of sula, wasting a tsunami tree. good. find us quick. in updates at the bay of pablo within minutes, 4000 people lost their lives and 79000. others had to be evacuated. how could a tragedy like this happened again the to find out unesco and the indonesian will saw as he's brought into tsunami specialist

professor cost us and alaska is at 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 lot of bulldozing in this area are ready. so a lot of evidence is very last for this, 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 this phenomena. science is very much like being a detective when i try and see there's a multiple murders. think you really have to piece like in the possible the

sequence of events that you know, i mean she'd 1st at least made houses collapse or wherever they collapse because of the earthquake and resumed. i mean, finished them off. what the people doing. why is it that some people die and some people know those investigations one to understand how the dissolves to unfold it. they go to trace the to nami, back to the original event that triggered the ways in the small fishing town of wanting cost us and, and 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 tremor, i went out on the deck of the boat. could i did you fill the trunk?

when get the yes, the boat shook because the water had gone down and the boat was ground to look up on what they could do in regards to stay with the boat, the of the what you style about. but the one of the defense these in front of them i was holding onto the month. i don't think i'm the yes. oh, okay. we have somebody sign up with that, go back. and then i. so the way of breaking on the distance, it was very fast and no time at all, it was next to the bows, pushing a 2nd room i can get on without the how hard was it? uh, i had time to see my house at the top of it was almost the same price as the bose have gives the guy the way to your house or driver. then that'd be the way it was about 5 to 6 maces high. the height of my house and didn't have to go to my cost us and, and not because it's a mystery when it baylock, this is usually protected from konami's out of 5 me to ways get this fall

twin ticket number to south of wanting him and freights. as conducting research in the town of pollute, with thousands of people died the accompanied by 2 indonesian scientists, him in fritz goes to the parking lot of the shopping mall. evans, looking to buy ways to better understand the dynamics of the wage, the consult cellphone, such edge taken at the time of the disaster. this is the exact spot that we saw on the fee. do you can see the billboard? yes, and all the way from people running away, people are running away. and that's the 2nd one is located. and now we can basically see how high the water is almost inside the billboard.

here the wave was move in full meters high. the to attend to far the source of the tsunami. human fritz needs to create some model of the devastating wave body terminating its heights at different points in the city and measuring how far it spread. and i tried to some detail survey news, so 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 point class and we can see how the wage goes through it took it and measure how high the wave is ever given incidence. and how fast the wave is moving across is through the house as washing away the houses and across

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 tsunami. that's submit the by of pablo, coding to the opposite ations, the most powerful wave spread more than 300 meters and thoughtful cost us an access 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 by the means. the polt and nami means the waves. the waves that destroyed the co, which this would now universal dates from the 17th century. it comes from another place on the planet most frequently hit,

but synonymy japan it was coined by fishermen who retained on a storm free day to discover they pulled had been devastated by waves. the most recent phenomenon in japan in 2011 caused a new to accident in focus, fema following a 9 point one magnitude as like this wave claimed the lives of 18000. people send an e mail. so normally it has no media or a logical cause, cause it's in the primary concepts. anomalies are earthquakes, minimal increase, that's the most synonymy is that generated by ops on next to comic activity. the cross consists of several launch plates. maxima pushes them against one another, a few, many meters to a few sentences. yeah. the

actually on a quote slide beneath the continental plates forming subduction settings, friction between these massive slabs of rock close this continental plates, the formation and with it a launch build up of energy. when the stress is released, it generates a huge undersea of quite comfortable and it's quick displaced is all the water at once and assume that kept keep them. and so for 4 kilometers, steve, 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 so 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 saw apartments come up as well. all the meetings, the

we cannot separate earthquake signs and sonata signs, longer duration of yours. great. it's a very good indication of how strong basically, it's like a zipper. if you have a smaller is greg, it's a short or up sure area. and that means the duration is sure. if it's a bigger, it's craig live, sumatra, 929 or japan mag. it to 9 plus events and base. if you have a very long zipper, that means the shaking will go on for several minutes. jesus christ will go to the the longer and more intense the 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

a che, on the indonesian island of sumatra, an earthquake rupture to fold line measuring 1200 kilometers. the 9 point one magnitude of quick last for more than 5 minutes. 15 minutes later, 55 meter waves hit the coast as it continues across the entire indian ocean bits. unami ultimately claimed approximately 230000 lives of talking lipstick scenes 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 events was also

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'm a reach 30 meters high up to the top of the hill over there. the roster of the mountains, but very few survived. one thing the coast for clues left behind by the tsunami, natalie is now made an exceptional discovery. first economics is south of bundle

a che obviously, so the off to the 2000 and policy, and i mean, this case was full of danbury pieces of wood. one moment the bookcase done. so i'm going to this cave has a very particular architecture that it is l shaped and it's entrances power alone to the kind of want to but how about funding? so every time the want to of us who not me comes to us of much these caves are you will not be it is retained inside. yeah. the problem that we bought a lot nationally as well, had a hunch. if this cave trapped the material carried by the 2004 to nami,

it could also have stored evidence from tough catastrophes. the, the cave had another particularity that, or they've colonized in form, and then the, the balance i'm not interested in ami is covered by a lack of gone on. i thought it was to pull it up the sun. well, i know that you can see the layers of glasgow and black light is on and i have somebody look on my sounds, but the me over the is the day is of guano or that dropping deposited between each tsunami. first of all is to form a t, a boundary delineation each separate event. this allows to nami, then a lot of quantum or they have to nami mole guano 10 as soon ami that mall quantity . so now me think one of the 2000 and focusing on me a total of 12

synonymy deposits make up this settlement overnight with the help of researches from single pose as 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. i mean the next event as about 2900 years and then faults and armies occurred 25 years. a pause about 3300 years ago. the oldest was about 7500 years ago. not very come from the day to obtain. here we have discovered that to nom is, are recovering it regularly. so but my back to the, i'm assuming to promote the, the, again this is the lesson for both the government and the people. busy

that we have to be vigilant, but it could 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 tanami is a could in the past, the 1st 2008 unesco has maintained a world wide tsunami man updated with scientists. nicest discoveries. $1200.00 sonata, these have been confirmed of the costs, $3.00 millenniums, the least,

destructive amount 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 good in other areas, especially in one region now considered safe from this kind of dissolves to 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 a forgotten dissolves to 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 to see us quite from nice to genuine . at least 600 people died and 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 the 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 the i'm intuitively, and scientists and the times however many of mccully recorded in a very precise way, full, the destruction that happened on the coast to records. and we have $2700.00 ohms of ation points between friends and decently confident that

christopher logan and his team use these special graphs taken at the time of the designs to, to match 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 tanami is a delicate task officer rule. the seismic zone is one of the most complex and to the effort complaint in the south rises to bullets, the raising plates and the news pushing corsica and sardine against the riviera, generating numerous seismic phones is

identifying the fault that calls the 1887 to nami, even possible newton is uh, montana. yeah. we using sophisticated size make investigation equipment, essentially canada so used to create waves. these will allow us to obtain a sonogram of the inside of the year, 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, but of the up to 5 days at sea, the ultra sound reveals not one but 3 phones below the sea floor. the location, so security number 2 is from the coast, corresponds to the epi center of the 1887 of quite the. then we'll follow that to you. of the salt suggest that they are still active and allows the scientists to model to possible to nami scenarios. look

forward to using the you. the 1st scenario is an earthquake equivalent to vast of 18. $97.00 with a $6.00 magnitude, which would break a full length of about 30 kilometers a wave height. so 2 meters and the 2nd big strain scenario is to envisage a rupture over almost the entire length of default. for example, 60 is a way to columbus is getting, which we've been producing is quake of magnitude 7 and wave heights. but good rate, 3 to 4 minutes is also twice got to make 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

chance have been drawn up with a focus on nice. but one thing remains trees. a rupture of the thoughts such economics has from the coast only in those 20 minutes of these occupation time before the waist breaks. not even a small. so normally 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 these on the spot nations. maybe the rainier and beach is just like many beaches, convenient ocean. i verify where there is, or is that in the summer week on the 5 tens of thousands of between. so there's one of each wave of possibility over some, not me, arriving within a few minutes. coastlines are popular with locals and tourists

all over the world. this makes tsunami warning systems. mold them all necessary impulse new where it cost us interlock has and him and for it's continue their investigation. 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 was the income and 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 wave of 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

indonesia, including the bay of pa, new a few slots monitors can detect any as click, etc in real time advanced algorithms allow them to send the night before mation 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. mount cross his mind off, give you a 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 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 communications systems in pollute. what is very alarming to me is that here 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 not me comes in. according to the takata center simulation wave, boeing close to the epicenter ac kilometers 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 of the entire page to this by being allows us to see how this wave came in and see the expense of innovation. 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 allows to confine to zone read to look for further for the sources to inside the bag. if to waive that devastation pollute, who had foamed in the ocean, it would have hit the entire coast line. human fritz and cost to send it like his realize that the epicenter identified by the to cause a warning center couldn't have directly created the kind of wave. the source of the tsunami must have been inside the bag itself. him and fritz and his indonesian colleague, god power set you return to the west and backs of the bay. they want to understand how the tsunami could have originated from this sheltered area. giga per, a search has connected new footage films nearby. the body is still over, there has been petition. so then you can see also in the background of these events

and it has been discarded. the font size yeah, local landslide. great. you have a small semi circular way that you can even seen the video. yeah. so i think this is going to be a localized impact and it is land slots. and i mean, you have a lot of illusions 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. okay, so this car actually is along the shore line. the land went into the ocean. and so we have a coast landslide. i don't think there's localized and i mean it's big enough to be the main source of the tsunami that wiped away follow or. 5 vonny on the other side

of the bay. the thing the antonia bay, researches discover 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 pollute, synonymy is finally revealed. a lot of assets looks nice, but that's pretty amazing. what the honda will be, asa where he is the risk you have to do. the trend 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 that all the way to the most can a cry about it. all the house is collapsed at the same time from south to know, like the slope of the house. so my an immense vault line cuts through the town and then extends into the bay for tens of kilometer. his

researches finally have the onset, it's this fault that calls the polluted synonymy. after 5 days, the field work and months of data analysis, they can find the reconstruct the sequence of events. on the 28th of september 2018 at 6 o 2 p. m a 7.2 magnitude as quick because ac columbus is north of polluted the epi center correctly identified by the to cause a control center doesn't directly trigger the tsunami. the quite corrupt should see us at a staggering speed of 14750 kilometers an hour within 2 minutes. this set land slides in motion all along the coast, creating a concentration of meats and all these. these ways then combined to form

a single powerful wave that swept across the city, the human fritz and cost us and alexis have completed their investigation. the reconstruction of the bay of pollute synonymy will help improve loaning systems all over the world. we just a think event, so now i'm is only slide can areas where you have some vaccine results. we now know just like what's happening here that so now i'm just gonna slide briefly much amy place where you can have and that's great. we are very concerned about this because similar earthquakes could take place in seattle. they could take place in southern california. they will take place in the going to be in, and they will take place and can be made during the s clinics sold slips. volcanic eruptions,

phenomena can be triggered by all kinds of tectonic activity. research carried out over the last 15 years has helped to improve warning systems, and basically adapt them to each risk. in japan, a country at the forefront of tsunami science. the technology is the most headphones g and research has no exactly with the next exhaust. it 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 no me scientist 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 for at least 20 years to the possible cause of rupture of the non co fault that runs along the countries west coast from 900 kilometers. i mean that's good on k 12, the threat of a non ca trough is very specific boston. so because it's located in front of all the economic centers of japan, whether tokyo, your sako 2nd or no go. yeah, i agree. yeah, all the cities are ongoing mobile areas. no technology can predict and quake, but japan has an extensive monitoring system in place ready to issue an immediate public warning. says the matter, listening to the fault of welcome when it will move and being able to sound the alarm as quickly as possible. and for that, we have the net system, which is just outside of sort of a the 2nd the next system is the most sophisticated suspect detector in the

world. it consists of around 50, under most and many of say the trees equipped with precious senses. so as monitors and extend, the roommates is installed directly on the fall line. so let me, if i listen i'm it would arrive between 3 and 5 minutes and the 1st cities with waves of 20 to 30 meters seats like then the wave enters 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 counseling. to determine the most effective evacuation 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 to model. now 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 go to a couple of minutes. so we got the one of 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 of 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 meta high waves simulation. well,

simulations are carried out to determine hazardous locations a need. for example, 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 amount 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, in that a mobile sign application displays ways progression and identifies the nearest sites that means one of the me session internet notifications will be pushed out to our cellphones. if you're watching tv and you'll have messages displayed on your screen telling you where to shelter with the soviet, what's also trouble finding research is essential, but limiting the impact of destruction is just as important.

as the 2011 sonoma showed ports of very dangerous places to be carried by foss, moving bullshit ships can become giant projectiles. the full professor has she most have from the university of covey, evacuating people quickly. daring, and, 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 and you're still in at any given moment. there are 30 to 50 boats sailing there for you that i'm ok can start with 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 have backed away one after the other in an orderly fashion that you know, i wonder why they like and that's why we're developing an artificial intelligence system and which will allow ships to evacuate from a news or automatically equate that one was the little guy. so

a ok well saga is the megalopolis of 8000000 inhabitants and the countries 2nd largest economic center is city build of a time unimed benjamin's below sea level surrounded by hundreds of kilometers of protective rules. the see if i see old dominion, what happened in 2011 was that the earthquake had a weekend. all the structures they switched to part of the walls had fallen with the crate. i think because one of the so known me campbells with fire safety mechanisms were no longer effective. you think yes, no, need to these up to date, even the most sophisticated technologies con, predict quakes. these artificial islands freak, same from the sea, along with the houses shopping centers and pitcher chemical industries built here could be destroyed in an instant. in the event,

if it dissolves to lock this inflammation campaigns and an effective public response will be the only way to save lives. the we mike sync with timing nature. it has always had the upper hand shown 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's the loss more than 15 seconds. move away from the beach. the

are we talking about private data isn't helping dislike crime. social media censorship because the digital network world not as done. so what are the biggest challenges? we'll talk about that shift in 30 minutes on d w. a loveseat. i love the smell of

a texture. there's only one thing i love about it and that's how it's made. can we do without factory farming and avoid climate disaster? will them meet? so the future be grown in a lab. the taste of future food, fake stake. 75 minutes on d w. the imagine that you're eating a hamburger and as you're biting into this juicy bird or your dining companion says to you, actually that hamburger is not made from kaos. it's made from golden retrievers. 2 2 2 2 2 2 2 in meeting cultures around the world,
