pandas in the why, the, we do appreciate your company of next a documentary about the global threat of nomics. stay with us. if you can, the why do humming does not get drunk. why do gravitational waves squeeze out bodies? how much do we need to put a pond print to help find the office gets lost on dw science, outtake talk channel, 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 to 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 power plant exploded off 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 in any region of the planets and coastal development makes everyone increasingly vulnerable. 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 pollute within minutes, full 1000 people lost their lives, and 79000. others have to be evacuated. how could a tragedy like this happened again the to find out you? let's go 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 to be a detective when a crime scene, there is a multiple murders you really have to piece like in the possible,

the sequence of events. dave, it's now me see 1st at least maybe the houses collapse or wherever they collapse because of the earthquake and resumed. i mean, finished them, what 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 one a 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, when there was a big tremor, i went out on the deck of the boat. could i did you feel good tremors?

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 of the ones you stay with that. but the, one of the defense, the in front of them was holding onto the mind. yeah. oh, okay. we have somebody sign up its i go back and then i. so the way breaking on the distance, it was very fast in no time at all. it was next to the boat pushing us check up our girl, my daughter on fire mountain. without that, how high was it? uh, i had time to see my house. the top of it was almost the same price as the bose have been said, that the original house or the, the wave was about 5 to 6 maces high, the heights of my house. and it never happened yet. it might cost us and, and not because it's a mystery when it by like this is usually protected from konami's out of 5 me to

ways get this for twin checking, how much is south of ronnie 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 a shopping mall ever looking to buy ways to better understand the dynamics of the wage, the consult cell phones such taken at the time of the disaster. this is the exact spot that we saw on the fee. do you can see the billboard, you're not away from the 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 more than full meters high. the to a den to far the source of the tsunami. and then 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 in 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 go 3 d space base, the light stands all the point class and we can see how the wage goes through a ticket 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 bank. the so means the polt and nami means the waves. the waves that destroy the colon. this would now universal dates from the 17th century. it comes from another place

on the planet most frequently hit by tsunamis, 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 media or a logical cause cause it's in the primary concepts. anomalies are earthquakes, critics, etc. most sonoma is that generated by all planets to comic activity . the cross consists of several launch sites. maxima pushes them against one another, a few, many meters to a few centimeters, a yeah. the actually on

a quote slide beneath the continental plates forming subduction, sens. friction between these mass of slabs of rock causes continental plates, deformation, and with it, a launch build up of energy. when the stress is released, it generates a huge undersea of quake. comfortable and they are, it's quick, displaces all the water at once and assume they're kept cute them. and so for 4 kilometers deep, we have 4000 meters of water that moves up to speed up an airliner. very quickly as we approach the coastal, the speed is reduced the way it 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

separate earthquake signs and sonata signs. longer duration of yours. great. it's a very good indication of how strong it's basically, it's like it's different. 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 is craig live, sumatra $9029.00 or japan mag through 9 plus events. and basically, you have a very long zipper. that means the shaking will go on for several minutes. crossed by the, the longer and more intense the embassy of quake. 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, and is quite rupture to fold 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 elliptic 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 wake up cold

14 on the science, which advanced considerably in the wake of this natural disaster. the, the of the numerous international studies launched and researched by indonesian geologist natalie is now led to major revelation the 8th. as soon i may reach 30 meters high, up to the top of the hill over there. the roster of the mountains, but very few survived on the thing the coast for clues left behind by the tsunami, natalie is now made an exceptional discovery. first it can nominate yourself

a bundle, a che i mean the off to the 2000 and policy nami, this case was full of danbury pieces of would you like me to be lucas young from them because to these can you pass 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 i've assumed i'm a comes to us of much these cave i you will not be it is retained inside. yeah. the problem is that the family by law natalie is now 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 cave had another particularity that the colonized in form and then the, the status of each student army is covered by a lack of gone on. i thought it was to pull it up this time. well, i know that this you can see the layers of guano in black. he is on i have somebody with online thumbs but they need over the years, the day is of guano or back dropping deposited between each tanami fossilized to form a t, a boundary. delineating each separate event and then it doesn't allow so nami, than a lot of guano, or they have to nami and mol guano. then as soon ami that mall quanto tsunami.

think one of the 2000 and focusing on me a total of 12 to nami, 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 output deposit corresponds to the 2014. i mean the next event as about 2900 years and then photo nomics occurred 25 years of cost 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 a 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 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. met updated with scientists. nicest discoveries. 1200 sonata, these have been confirmed over the past 3 millenniums. the least destructive 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 c, nomics are located along the pacific. bring a science where 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 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 a football and disaster. trolling

through local archives. research is discovered that on the 21st of february, 1887, a section of french and italian coastline was hit by a to me so hard to know me. wave triggered by and i'm just see us quite from nice to general. at least 600 people died on tens of thousands, lots of the homes. today, the riviera 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 assess it's condition do so you know that you know how many to battalion scientists into 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 disaster to mount 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 after complaints in the south rises to both the raising plates and the news pushing corsica and so danny, 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. not a 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 film. the location . so security number 2 is from the coast, corresponds to the epi center of the 1887 of quite the symbol for that to you. of the salt suggest that they are still active and allows the scientists to model 2 possible tsunami scenarios.

using the you, the 1st scenario is an earthquake 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 stream scenario is to envisage a rupture over almost the entire length of default. for example, sixty's way to columbus is which would then produce another quake of magnitude 7 and wave heights that could read $3.00 to $4.00 maces off with white. 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 so she can nominate his from the coast. only in those 20 minutes of evacuation 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 only tenant and he's on the spot nation. maybe the rainier and beach is just like many beaches in the indian ocean. i verify what there is and use that in the summer week on the 5 tens of thousands of between. so there's one of each wave impossibility over some, not me arriving, you know, within a few minutes coast lines of popular with locals and tourists

all over the world. this makes tsunami warning systems fold them all necessary in hulu, where it cost us and they're like has and him and for it's continue the investigation . it's the nami warning system was set up after 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 it was a run, those are like this. people were shouting all over the place. the boat is rising, the want is rising up. i, i this witness says people here, but completely taken by surprise. no way that reached this area. the. the investigation continues at the tanami monitoring center in the indonesian capital to content.

this control tower monitor seismic activity throughout indonesia, including the bay of pa, new a few slides monitors can detect any escalade, 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 of the size monitors key on putting us think he was on duty that night on the bubble at the time of the earthquake and tell who the magnitude was. 7 for 2 minutes and then just afterwards the magnitude rose to $7.00. that was when i ran to the 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 2 casa, every time somebody at the center is here, a problem. 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 in and not because consult cctv footage. the friday september 28th 6

o 2 pm. the us quake hits the bay of police. the trim is lost a little over a minute. the . the quake 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 the cross. he's mine to austin. we are quick because he's so close to the one there. perhaps it's not even come and 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. the, 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 communication systems in pollute. what is very alarming. 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 often we are quick hits. it's not me comes in. according to the

takata centers simulation wave, boeing close to the epicenter ac can now much 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 important how the birds i view this by being 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

allows to combine the 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 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 waves. the source of the tsunami must have been inside to buy himself. 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. gig, our purse that has connected new footage film nearby. the bar dispute over there, the petition. so then you can see also in the background of these the events and then it has been discarded. the font size yeah,

local landslide. those are great. you have a small semicircular 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 eluded materials that wants to shake it to him and fritz. the low intensity of this says ways sumed at the very moments of its best suggest it was treated 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 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 hollow or vonny on the other side of the bay. the thing the antonia bay researches discovers

several others submitted on science. all sources of meaning to nami. but when they look further in the full story of the pollute synonymy is finally revealed the gases look. but that's pretty amazing. what the honda will be asa where he is the re do you have to do? the trim is open ended, then closed it and opened it again. you have to do 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 as an immense thoughts on cuts through the town and then extends into the bay for tens of kilometers researches finally have

the onset. it's this fault that cause the polluted tsunami of to 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. because ac columbus is north of police. the epi sent to correctly identified by the to cause a control center doesn't directly trigger the tsunami. the quite corrupted 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. 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. we just the think events, so not only slide can areas where you have some vaccine results. we now know just like what's coming here that so now i'm just going to slide pretty much any place where you can have and that's great. we are very concerned about this because similar earthquakes could take place in seattle that can take place in southern california. they will take place and they're going to be in a big, big place in the main 3 s clinics sold slips. volcanic eruptions, phenomena is, can be triggered by all kinds of tectonic activity. research carried out over the

last 15 years has helped to improve warning systems and visual, 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 exhaustive 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 a tsunami sign to 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. the possible cause of rupture of the non co 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 ca trough is very specific boskus because is 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 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 welcome when it will move and being able to send me along as quickly as possible. and for that we have the dynette system, which is just outside of socket base. the 2nd, the genetic system is the most sophisticated seismic detector in the world. it consists of around 50, under most and many of the trees equipped with precious senses. so as monitors and

extend the roommates is installed directly on the phone line. good. so then me. if i listen, i would arrive between 3 and 5 minutes and the 1st cities with waves of 20 to 30 meters like it. 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 accounts and to determine the most effective evacuation chance and test protective rules. the dissolves to prevention sent to appear. so universities stimulates the effects of a non 5 fold tsunami in a pool. collect where 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 c 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 and the several maces. so for the pole, simulations, supplemented by visual bonds. this one developed by professor his eyes she's team depicts the progression of it. so nami, in tokyo bay, the although it's 5, you know, much is 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,

a road will be hit by a way very fast. well, so should not take refuge that you get to this building will have its entrance blocked by the current of this to nami. so you should not have that. so not this moment that and you get to, i can i to cause the these models enable 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 stones. one of the me session internet notifications will be pushed out to our cellphones. 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 research is essential, but limiting the impact of destruction is just as important

as the 2011. so nami showed ports of very dangerous places to be carried by foss. moving bullshit ships can become shy and projectiles. the full professor has. she must have from the university of covey, evacuating people quickly during and then 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. and i don't think it's that will, that we have no guarantee that in the event of a so now me of this situation and many have never experienced everyone would keep cool and that the ships would evacuate one after the other in an orderly fashion that my phone, you know, i wonder why they like, that's why we're developing an artificial intelligence system and which will allow shift to evacuate or maneuver automatically. of course, i won't do that. we'll go through a ok. well, saga is the megalopolis of 8000000 inhabitants and the countries 2nd largest

economic center especially build over time unimed benjamin's below sea level surrounded by hundreds of kilometers of protective rules. the best seemed to be what happened in 2011, was that the earthquake had weekend all the structures they switched to part of the walls had fallen with the crate. i think so when the so no me came up with our safety mechanisms were no longer effective. if the just need to these up to date, even the most sophisticated technologies con, predict quakes. these artificial islands reclaimed 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.

we might think we'd timing nature bought it as always had the upper hand, the show lines have always attracted people, but the rapid immunization of these areas makes us old and move on to the official warning systems are in place in 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 the floss more than 15 seconds, move away from the beach. the

the is it ok? oh, can you set donates? we hope to create furniture. this person you maybe try to predict to people in some spot that feeling and someone, the design of the doctor, and mrs. from to how does the full homes with autistic joy? and every piece is infused with a capitals, a history of feedback. in fact, she minutes on the w a remote village in western ukraine shortly before the war. many here see no future for themselves.
