fire deal. the up next is the documentary monny's danger from the gaps that is after the break. don't forget, you can find all the latest news from around the world on our website. a, c, w dot com for further amberlynn from me and the entire team. thanks for being with us today. the green you feel worried about the i'm the old house of the on the green fence. somebody is clear. we need to change. join me for the size of the green transformations. for me to use me. ah

ah. soon on these deadly waves that have the power to destroy entire cities. in a matter of moments, there was little public awareness about them until december 26th, 2004. that was the day a gigantic synonymy in the indian ocean, killed more than 230000 people. images illustrating the pool of this natural phenomenon shopped the world 7 years later, in 2011 a nuclear power plant in cuckoo shima japan exploded. after being engulfed by an earthquake generated army. since these tragedies, scientists rushed to the scene, redoubling efforts to determine what causes these killer ways. because that knowledge said line,

it's clear that soon armies can strike any region of the planet. urban isolation has made coastal communities even more vulnerable. can to non research protects than the oh, on friday, september 28th, 2018. earthquake followed by a tsunami, devastated an area of the bay of par lou on the indonesian island in la away see within minutes 4000 people lost their lives. 79000, others had to be evacuated. how could this new disaster in indonesia occur after

the devastating 2014 army? $22.00 nami specialists were commissioned by unesco in the indonesian authorities to investigate cost us in our lockers at the university of southern california and herman fritz, the georgia institute of technology have arrived to conduct field research quite impressive to see the devastation there. now, 3 weeks after the event here we can 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. the researchers will be combing the debrief traces of the wave time is of the essence cleanup operations have already raised valuable evidence. and the monsoon rains that you to start seeing all

me working as a synonymous scientist is very much like being a detective privacy. there is it multiple murders taking place. you really have to piece like in a puzzle. the sequence of events that unami should 1st and this made houses collapse, or where do they collapse because of the earthquake and was from now me famous them off. what one of the people doing, why is it that some people died and some people did well, i, the to research is want to determine how the disaster unfolded their goal to trace the scene or me back to the event that triggered the wave. the cost us, you know, like, has goes to meet survivors in a small fishing town of $1.00 when the wave hits come, do la teeth was on his boat,

100 meters from the shore. also both of those young are when the 1st ways came in there was a big tremor and when my dad was that he got pop, could you see the tremors on the boat? yeah. yeah. just because the whole goal was rocking because the water level had drunk, the boat had run the ground. what they could do either that and she stayed with a boat of the west. did you stay on the boat? you went about did upon the forgot to hold onto the mash. yep. and then i saw the wave approaching in the distance. it 2 separate sally was very fast. 2 can be reached the boat in no time at all. pushed on the land grown my daughter. but you know, roughly how high was it that you could see? my house was almost at the same height as the boat had been the one that was your

house over there on the way it was about 5 to 6 meters high. i my home is thinking i didn't know who my me close to. no luck has he's puzzled. how could a funny me to high wave have crashed on to the shore here in a bay that up until now had not been seen as seen on the hazards? 20 kilometers south of one e. herman fritz is conducting research in lou tucked away at the back of the bay. the town is home to 350000 residence. thousands of people lost their lives here. accompanied by 2 indonesian colleagues, herman fritz drives to the parking lot of a shopping center overlooking the bay. he's investigation into the dynamics of the wave relies heavily on videos from mobile phones,

the exact spot that we saw on the field. you can see that a lot, yes. and the way from people running away, people running away. and that's the 2nd way located side one. so now we can basically see how high the water is almost in the billboard the wave reached a height of more than 4 meters for and then the to determine the cause of the synonymy term and needs to create a computer model of the devastating wave for this, he has to determine its height at different points in the city and measure how far

it spread in land. i tried to some details serving years ago to try to get a 3 d stand. and the purpose of that is to get 3 d space. but the light stands all the point class and we can see how the wave goes through it. so if you measure how high the wave is every given instant and how fast the wave is moving across, the, how's the washing of a to how's it and across the street in fritz follows the weights, traces. after flooding the parking lot, it's swept deep into the city. evidence of the force of the wave can be found in the smoke located just 100 meters from the shore. ah. this on group, we have this grill here and we see this rafter debris inside. so we know that this denali was at least to this height of this rack. and then up here we see the actual

primary scenario line, which is this one right here. and we can also see it in the window. if you look at the blue sky, we actually see a mud line going through there. and then we look that over here, we also see the mud line coming around coming around, coming around. so the saddam is coming pretty much at the height of my head through this mosque. and that's also very difficult hydro ready because usually when your water is for this height, you cannot stand anymore, you will be thrown to the ground by the waters. so can be difficult to survive. the $2.00 to $3.00 days of field work, the 2 american researches and their indonesian colleagues can now produce their 1st simulation of the synonymy that hit the bay of pollution. they establish that the strongest wave of 300 meters in land, that cost us lockets and home, and fritz are only at the start of their investigation. they now have to identify

the event that triggered the deadly wave and find out how it could have swept into the bay. su means to port nami, the weight, the weights to destroy the pores, me the word. now in universal use dates from the 17th century. it comes from the place on the planet and most frequently affected by nami, japan. it was coined by fishermen when returning to show on a storm free day. they discovered the waves had level villages. the last 2 now me to hit japan cause the sucrose sheeman nuclear disaster in 2011. it was triggered by the quake measuring 9 point one on the richter scale,

the wave killed more than 18000 people soon. i mean, or can cause a synonymy has no meteorological cause that's the primary cause of synonymy earthquake and sequence on the vast majority of soon on these are generated by c quakes, which in turn, a triggered by the earth tectonic activity. the earth crossed is composed of several large plates. the movement of magma pushes them against one another. a few mill to a few centimeters a year. the oceanic plane slide beneath the continental plate, creating subduction zone. friction between the plates can cause the formation of the continental plate which accumulates a gigantic amount of energy. when this energy is released, it can cause a huge undersea earthquake.

on earthquake suddenly puts all the water in motion still in that cap. keep them in at a depth of 4 kilometers. we have 4000 meters of water moving at the speed of a passenger plane. and i've been linear heavy weight flows down near the coast but increases in size. so we don't, i create weights like we saw in 2011, 20 to 30 meters high. i met all the meetings. yes. we cannot separate earth science and synonymous size long but iteration of the earthquake. it's a very good indication of how strong you are basically like a zip or if you have a smaller break, it's a short or up sure area. and that means the duration is shorter. if it's a bigger, it's craig laxom audra, $99.00 or japan maggots are 9 plots is events. and basically you have

a very long zipper. that means the shaking will go on for several minutes. jesus christ. why would you be the longer and stronger and under a quake, the more powerful that you know me. it triggers as in the indian ocean. c quake of december 26th 1000 in full me a full located 100 kilometers of thunder. on the indonesian island sumatra ruptured along the length of 1200 kilometers the massive 9 point. one magnitude under the quake lasted more than 5 minutes. within 15 minutes, the 1st weighed up to 35 meters high,

smashed into my truck. while other launch waves rippled across the indian ocean, you know, 230000 people lost their lives. the waves advance with capture for the 1st time on the video by hundreds of people caught up in the disaster. the world was shocked by this devastating show of natural force, a force little understood at the time. for scientists, it was a wakeup call, energizing research into tsunami been still in its infancy since 2008 unit sco has maintained a global phenomena tracker. it's a record of 2 nami occurrences over the past 3 millennia. to date, researches have identified 1200. the least destructive are in white and most deadly

in read. each of these dots represents the potential danger for the future. 70 percent of synonymy, a located along the pacific ring of fire, where most of the earth subduction zones located. oh, the entire loop. to see no knock has been turned and fritz continuing their research at su nami, early warning system was set up here after the 2004 disaster. so why would there so many victims in 2018? there were a lot of vendors here selling food. it was really busy, but at 1st we heard a rumble, gave long the people started screaming on the waters rising decently witnesses. the crowds in the roads near the beach were caught totally off guard by the wave. no warning sounded here. our

investigation continues to see nami monitoring center in the indonesian capital to counter this control tower monitors seismic activity across indonesia, including the bay of par lou. seismic ologist here can detect any under the earthquake in real time. advanced algorithms allow them to simulate the formation of it's in ami and worn coastal communities before the 1st wave hits. since its introduction in 2000 tonight, the system has issued 22 alerts, saving countless lives. why then did pollute fail to receive a warning on september 28th, 2018 key and put in a think he with the science molig just on duty that night? that's about the earthquake and pollute registered

a magnitude of 7 for 2 minutes by the den. just afterwards the magnitude rose to 7.7 moment. i instantly ran to the table where we stimulate economic in the other. i may just talk more the length when i mean the center in jakarta registered in earthquake 80 kilometer north of palm bay. early in the evening the epa centers here and here is kalu. according to the simulation, it's unami risk posed by the surf quake was only moderate, nevertheless, and alert with triggered within the prescribed time limit. 5 minutes after the earthquake. so won't went wrong. in

cost us to no luck as we'll discover the answer with the help of 2 private surveillance cameras. ah. friday, september 28th 6 o 2 p. m. the earthquake hits the bay of par lou. it lasts longer than 2 minutes. did you experience the earthquake was incredible. you couldn't stand up. never did impossible. i was there under camera to hang onto the gate, then it calm down and i went out. he crossed his mind after your quick because he's so close to the water for hospital. i mean, we come, they've always said a base of a doesn't have to know me so that it's in the open sea where their current level unit happened here. and these images provide the

researches with key evidence on the chronology of events. the time on the cctv footage reveals that barely 2 minutes elapsed between the end of the earthquake and the onset of the denominator. such rapid succession had never been recorded before. the tsunami warning issued in jakarta went out after the wave hit pollute. when all of its communications systems were already down. what is very alarming to me is that here the earthquake, 3, give me very quickly. so we need to understand how this happens. and also,

what is the timing, how quickly after the earthquake kits in synonymy comes in? according to the jakarta center simulations, it should have taken a wave generated near the epi center ac kilometers north of the bay, about 15 minutes to reach pollute. how is it possible for this wave to advance with such speed and force on the bay of pollute the to find answers the researchers take to the extremely important to have a birds eye view just by being up from the air. it allows us to see how this wave came in and see the extent of innovation. scientists struck by what they see there are alternating areas of devastation and

intact. but that's not all. once we get outside of the bay wave disappears very quickly. and you're looking at very beautiful indonesian beach that are ready to confine to zone where to look for further for the sources to inside debate. to waive the devastated power lou had formed out in the open sea, the entire coast would have been effected long term and free and cost us in lockers down to the deadly we is generated at the epi center identified by the jakarta warning center. they believe the source of the tsunami must have lain inside the bay itself or turn and fritz and his indonesian colleague, parasitic returned to the west coast to gauge how it's an army could have originated in this sheltered area. giga parasitic has received a new footage that was still nearby, and i think the bar is still over there. so then you can see on the big on of

these events. and then this is rendered started the response site yeah, local as life goes on next, reagan for years. great. you have a small semicircle where you can even seen the video. i think this is going to be a localized impact landslide tsunami. you have a lot of aluminum material, you want to shake it and we'll go to whom and freeze the low intensity of this 1st wave. suggest sit with triggered by a coast landslide. but that alone doesn't explain what cool is. but su nami, that devastated the bay. here we have evidence because we have a coastal car. okay. this car actually is along the shoreline, the land went into the ocean. and so we have a coast landslide. i don't think there's localized. anom is big enough to be the main source of the denominator, wiped away follow,

or vonny on the other side of the bay. surveying the entire bay, researches discover several other similar landslides. all of them could have triggered many armies. but it's only when the team looks further inland and it finds the missing piece of the puzzle. in a lot of look, this is remarkable. honda, this is the trench behind now with tremors opened it and closed it and opened it again to the monday. ah, a few 100 meters further on a 2nd witness points out the extent of the destruction was i'm wondering if the entire row of houses collapsed once a month. not all of the how does collapse at the same time from south to north? as you can see by the slope of that house, there might a deep, full line opened up,

cussing clear through the town, causing the buildings to collapse. it continues on into the bay for many more kilometers. finally, researchers have the answer. it is this fault line that caused the parlors to nami, after 5 days out in the field and months of data analysis, the sequence of events that last piece together on september 28th, 2018 at 6 o 2 p n. a 7.2 magnitude earthquake struck 80 kilometers north of par lou. the epi center correctly identified by the to non the monitoring center in jakarta, did not directly triggered the tsunami. the seismic waves travelled through the earth's crust at the extremely high speed of 900 kilometers per hour, generating a fault that opened up across the entire bay. that triggered land slides all along the coast, which in turn generated

a series of many to nami. the energy of all these many to nami, is accumulated in the depression of the bay, combining to form a powerful wave that swept across the town, herman fruits and cost us to no luck as the investigation has come to an end. the reconstruction of the bay of pollute through nami will help improve warning systems all over the world. we used to think that phenomena is only like in areas where you have some ducks in zones. we now know that's like what's happened here, that you're going to like pretty much any place where you're going to have and that's great. we are very concerned about this because similar earthquakes would take place in seattle that will take place in southern california. and they will take place in the going to be in big, big glazing and let me me

watch the water watch when what's done to watch a horrible earthquake. what a frightening sound of the sea and the howling of a great people. these woods by the italian poet pit truck. describe a strange storm over the city of naples in the 14th century, 700 years later. vulcan ologist tomorrow. rosie was intrigued by pet trucks. description. rosie has worked on naples emergency plan in case mount vesuvius erupt . most unami that generated by sea quakes and full lines, but they can also be triggered by volcanic eruptions. they've got full testimony, denado, the quest of ad chart witnessed an exceptional phenomenon that struck the city of naples normal force. and man, though he was asleep not far from the throne, when he heard such loud strange noise that he thought it was an earthquake,

remote or sound good for the pitcher i rushed to the harbour like so many other people, though we drove past and saw with his own eyes that it had been completely devastated yaki last inquiry d b. sooner than paul aside from his descriptions of the destruction, petra also wrote of hundreds of dead and dozens of sunken ships. to morrow, rosie, it's obvious that the strange storm was at synonymy. the trunk liberal car look at that time. petra could not have known that it was a soon ami money because it was an unknown phenomenon in the middle agency. all julie, of course, that there will be a day, we are certain it was soon on the top of the top. don't want to avoid a repeat of the catastrophe. the vulcan ologist has been searching for the cause of the su nami, that wrecked naples harbor in 1343 says record of the 14th century eruption of

mountain v. as in the gulf of naples. so mal rosie has focused on another volcano, located 200 kilometers from naples. stromboli is one of the most active in the region, are in 2002, and a reduction caused a flank of the mountain to collapse into a 10 meta high tidal wave re sea island. the wave spread across the terrain in sea and much weakened, reached the bay of naples could have far more powerful eruption of strong belief triggered the tsunami, described by pet trunk 700 years ago. above the village of san vin schanzer on the slopes of the volcano, archeologists r levy is excavating the remains of the small church. she's provided morrow, rosie with his 1st clues cup yam ok every point i mean to dramatic. if we knew that

a dramatic event led to the sudden collapse of the building goes out, probably a powerful earthquake because we found large blocks of stone inside on the church floor. the case of the name. in order to date, stromboli past activity, archeologists examined 3 skeletons found in the remains of the church. the skeleton was in a grave that was dug through the layer of collapse tiles that fell down when the church collapse. so this person was definitely a witness of the catastrophe, possibly a victim, possibly a survivor. this government had been dated by carbon 14, in the middle decades of the 14th century, sedated. the earthquake that shook the island of bali coincides with that synonymy disaster described by pit truck in the bay of naples when the church

collapsed. it was not rebuilt, which is surprising, and indicates a major change in human occupation at this location. it is likely that the island was abandoned until the 1600s. the event was so traumatic that the island of stromboli remained uninhabited for 10 generations and more than 200 years. following these revelations, now real rules, he began his own excavations. he hoped to find clues, linking the activity of the volcano, to the unami, described by patriarch in 1343 more than 4 meters on the ground. the vulcan knowledge is finally discovered an intriguing mix of sedimentary deposits for the policy. it's an army no longer. this unami deposit is by far the largest we found it's a piano cabin. we dated it to 1350. as evidenced by the materials in

a cackling jamel. they are like up to us, paul thought, well, nothing look at the size of these perfectly round table stone. i mean, they must have come from the be probably neither the less be green the, the presence of such a large sized elements prove that this nami was extraordinarily powerful in that. so now we have a one in there for the vulcan ologist. it'll make sense. the powerful wave, the flush, these large pebbles, 200 meters inland, from the beach, occurred at precisely the same time as the earthquake that destroyed this small island church. there is a clear link between the erection of the volcano and the tsunami. las shiara del fuko its own this impressive flank that all the volcanic material ejected by stromboli accumulates 700 years ago. and a russian may well have sparked landslide on the shiara del fuko. the would have held many millions of tons of accumulated debris into the sea,

triggering that synonymy that reached the bay of naples. but as we remain, taylor strongly called us who have given. trumbull is current activity. we believe the load of debris presently accumulated on the shattered l. worchol, comparable to levels at the time of the sou nami described by petra screven fell now ro rosie the landslide caused by the 2019 interruption with just the harbinger of a much more serious disaster to come. the shiara del fuko, he says, could collapse into the sea at any moment. the island of stromboli is under 24 hours surveillance to alert authorities, residents, and tourists in the event of danger. but what consequences would its unami have on a city the size of naples portal opposed to docket?

you see synonymy cape or something over here and these are the people are completely unaware that is to nami, from somebody could hit naples to see what i may want. the phenomenon. that's what i know the lyrically in the case of rare natural phenomena. actually, people tend to believe that there is no imminent danger since that film and keep play. so c, l pretty cool in the computer generated model tracks the course of the 1343 phenomena. it gives an idea of what could be in store for naples. a part of it all off rent. i mean, you would take under 30 minutes for this. you know me to reach the gulf of naples from strongly agree. the devastation would be unimaginable and creativity for people in markets. you can leave it with all the boats in the harbor behind me would be hurled onto the street, so speak to proud a lot of the water would gush into the subway and drown all the passengers. i

forgot. so i guess the problem is the busy streets will be submerged. sporadic event that very little promote that it would be a pucker lifting all that, i mean people seen, but that's exactly what what happened without an early warning system. senior year visa squeaks landslide. volcanic eruptions, all of these natural phenomena contributes konami's. research carried out over the last 15 years has provided a better understanding of the threat. it's also helped perfect warning systems and better adapt them to the specifics of each risk zone. the technology is most advanced in japan, a country at the forefront of synonymy science research is here feel they know

exactly what will cause the next disaster. these images from a government to when it's raising campaign broadcast in march 2018. to prepare people for a to nami, that scientists say has an 80 percent probability of occurring within the next 3 decades. to film explains how people should react, but also predicts the likely scale of the disaster with 350000 victims and infrastructural damage impacting the japanese economy for at least 20 years. the cause, a rupture of mankind trough a 900 kilometer long ocean floor, trench along japan's west coast. and tough. the thread of the non car trough is very specific because all the economic centers of japan could mean whether tokyo or soccer or no or in areas down

to date, there is no technology that can predict earthquakes. but japanese scientists have developed a monitoring system to warn the public the moment seismic wave is registered it says indicative definitely need to be able to detect movements as soon as possible and then issue a warning. well, if that's what a donor system does is just right outside the bay of soccer. the knit system is the most sophisticated seismic detector in the world $29.00 small underwater observatories equipped with pressure sensors, size, moments and accelerometers are installed directly on the full line off the coastal soccer issues in alert with the very 1st tremor. that's in any way. quite some unit . it will take 3 to 5 minutes, but the sooner i me to reach the 1st cities with waves 20 to 30 meters high. don't sweep into o soccer bay in flood parts of osaka and co becca. but it could be no time to clean

. it can be artificial islands would be the worst hit. with waves of 3 to 5 meters after 30 to 45 minutes. you saw on the output call accountant. to develop effective evacuation plan and test protective walls. the disaster prevention center at kyoto university simulate the effects of mankind, trough, earthquake in a pool. skylark, one or 2 of the 9, we are almost certain we be dealing with a magnitude 9 earthquake. ok. so now and then it would cause a soon ami couple you to that don't want him us hero as she has model the arrival of a wave with an average height of 20 meters. that's the equivalent of a 6 story building in a city directly facing the name control. the walls would weaken the waves impact, but the protective barriers would quickly become submerged under several meters of

water. the simulations of supplemented by computer models, they've allowed to hear a team to predict the pa, to me would take in tokyo bang the low. it's 5 kilometers inland. the district around b olympic stadium could be buried under a 9 meter high wave simulation. why go? well, you got to use simulations are carried out to identify hazardous locations, couple a bar door, for example. road that would lead quickly is not suitable as an evacuation root can i, to one of the entrances to many buildings would be blocked by water. so they offer no shelter, not this mono. do i kill to university has used the simulations to create an interactive evacuation plan in an emergency. an

app shows the progression of the waves and identifies the nearest safe stones. when at the session, we get information on our cell phones and on the internet. at the deal, we've got semi television stations, also broadcast warnings with instructions on what to do to get to safety. what topics saving lives is key. but scientists also want to minimize structural damage. mm. that's unami of 2011. once again showed that common areas are extremely dangerous places to be during a tsunami, which transforms ships into giant projectiles. for hero tada hershey motor of co they university. the harbor is a priority evacuation zone. while i was in here in conners at the state of

soccer being it's very busy during the day. so if you're taking a look at any given time, there are 30 to 50 boat sailing there. you know, we have no guarantee that in the event of a su nami, a situation that many for experience, everyone would keep their cool, and the ships would evacuate one after another in an orderly fashion. no, i want, i want a month. so, you know, that's why we're developing an intelligence system to evacuate ships automatically from an awful lot. you know, despite technological advances, japan is seemingly living on borrowed time or soccer. a city of 8000000 inhabitants and the country 2nd largest economic center is built on low lying flat lands. it's surrounded by hundreds of kilometers of protective walls. if i seem to be only secret problem on the 2011 earthquake weekend,

all the walls impacted emulated parts of the barrier collapse. so it was an offering effective protection before the sonoma arrived. if you just need these up to date. even the most sophisticated technologies cannot predict earthquakes. these artificial islands have apartment block shopping centers and petrochemical plants in public education and emergency management can reduce the number of fatalities. in the event of a to nami. we often feel like we've tamed nature, but time and again. nature, proofs are wrong around the world phenomena. research has made great strides, but every new disaster puts the technology's device to protect us to a new test. if we built a bar,

blaze, hospitals, public buildings, houses in areas that there's a high hazard where i've been layers and layers of them. and with time, what we are around the world is that our ability from disaster keeps increasing. instead, the waterfront living has an enduring appeal, but the uncheck turbine is ation of coastal communities is a recipe for disaster. even with increasingly sophisticated technologies and early warning systems. applying common sense to our understanding of nature is more important than ever. we say this worldwide, if you're near the coast and you feel any kind of ground shaken that last more than 15 seconds, move away from the beach. the
