Witness says the crowds in the roads near the beach were caught totally off guard by the way no warning sounded here. Our Investigation Continues at the Tsunami Monitoring Center in the indonesian capital jakarta. This control tower monitors seismic activity across indonesia including the bay of palau. Seismologists here can detect any undersea earthquake in real time advanced algorithms allow them to simulate the formation of a tsunami and warn coastal communities before the 1st wave hits since its introduction in 2008 the system has issued 22 alerts saving countless lives why then did palu fail to receive a warning on september 28th 2018. In a scene he was the seismologist on judy that night. I guess that. The earthquake in palo registered a magnitude of 7 for 2 minutes then just afterward the magnitude rose to 7. 7. I instantly ran into the toss table where we simulate tsunamis yagami more dealings and i mean the center in jakarta registered an earthquake 80 kilometers north of palm bay early in the evening. The epicenter is here. And heres. According to the simulation the tsunami risk posed by the surface quake was only moderate nevertheless an alert was triggered within the prescribe time limit 5 minutes after the earthquake. So one went wrong. Last assume the lurkers will discover the and so with the help of 2 private surveillance cameras. Friday september 28th 6 o 2 pm the earthquake hits the bay of power loop it lasts longer than 2 minutes. How did you experience the earthquake it was incredible you couldnt stand up impossible i was there under camera 2 i was hanging on to the gate and it calmed down and i went out to do call. Cut off. The grocery shop close to the water for help to try. Out the net that theyve always said a bays a bay a doesnt have tsunamis. That its in the open sea where they occur you know it happened here and said that. These images provide the researches with key evidence on the chronology of events the time on the c. C. T. V. Footage reveals that believe 2 minutes elapsed between the end of the earthquake and the onset of the tsunami. Such a rapid succession had never been recorded before. The tsunami warning issued in jakarta when town after the wave hit palu when all of its Communication Systems were already down. What is very alarming to me is that here the earthquake triggered the tsunami very quickly so we need to understand how this happens and also what is the timing how quickly after the earthquake hits. To the jakarta centers simulations it should have taken a wave generated near the epicenter 80 kilometers north of the bay about 15 minutes to reach palu. How is it possible for this way to advance with such speed and force on the bay of palu. To find answers the researches take to the air. Its extremely important to us cover birds eye view of the kurds it is really up to care for people to go hours or see how history will move in simply extend an invitation. To scientists are struck by what they see their alternating areas of devastation and intact nose but thats not all once you get outside of the bay the wave disappears very quickly and youre looking ever very beautiful indonesian beaches saturday hours to can find the zone where to look for further for the sources to inside tibet. The wave that devastated palu had formed out in the open sea the entire coast would have been affected. And fritz and cost us down to the deadly waves. Is generated at the epi center identified by the jakarta Warning Center they believe the source of the tsunami must have lain inside the plane itself. And then fritz and hes indonesian colleague. Returned to the west coast to gauge how it tsunami could have a region and to be in this sheltered area. Para city has received new footage that was filmed nearby. The bar to stay over there. So then you can see all. These events and then this is when this started this was like. Yeah a local landslide. Victory but here is great you have a small semicircular wave that you can even see the video here so i think this is going to be a localized impact of this landslide tsunami you have a lot of aluminum with you think once you shake it if you. Put hooman fritz the low intensity of these 1st wave suggests it was triggered by a coastal landslide but that alone doesnt explain what cools the tsunami that devastated the bank here we have evidence because we have a coastal scar ok so the scar actually is along the shoreline. Went into the ocean and so we have a coastal landslide i dont think theres localized tsunamis big enough to be the main source of the tsunami that wiped away or on the other side of the bay. Surveying the entire bank researches discover several other similar landslides all of them could have triggered may need tsunamis but its only when the team looks further inland that it finds the missing piece of the puzzle. And. They want to look this is remarkable this is the trench. Trimmers opened it and closed it and opened it again at the front door with. A few 100 metres further on a 2nd witness points out the extent of the destruction was i wanted i mean the entire row of houses collapsed on all of the houses collapsed at the same time from south to north as you can see by the slope of that house there. A deep full line opened up cutscene clear through the town causing the buildings to collapse it continues on into the bank for many move kilometers. Finally researches have the answer it is this fault line that cools the palu tsunami. After 5 days out in the field and months of Data Analysis the sequence of events has at last been pieced together on september 28th 2018 at 6 o 2 pm a 7. 00 magnitude earthquake struck 80 kilometers north of palm. The epicenter correctly identified by the Tsunami Monitoring Center in jakarta did not directly triggered the tsunami the seismic waves travel through the earths crust at the extremely high speed of 900 Kilometers Per Hour generating a fault that opened up across the entire bank that triggered landslides all along the coast which in turn generated a series of mini tsunamis the energy of all these many to nanis accumulated in the depression of the bank combining to form a powerful wave that swept across the town Hermann Fritz and cost us in a lot because the investigation has come to an end a reconstruction of the bay of palu tsunami will help improve Warning Systems all over the world where you still think that tsunamis. Can areas where you have subduction zones we now know just like what happened here that tsunami is going to bring any place where youre going to have an earthquake we are very concerned about this because similar earthquakes place in seattle grace in Southern California they could take place in the caribbean and big big racing and they make their own. Wash walls of water wash weans want funda water horrible earthquake water a frightening sound of the scene and the howling of a great people. These words by the italian poet petrarch described as strange storm over the city of naples in the 14th century. 700 years later vulcanologist morrow rosie was intrigued by petrovs description grossly has worked all night bills emergency plan in case Mount Vesuvius erupts most tsunamis are generated by sea quakes and full blinds but they can also be triggered by volcanic eruptions. The monastery request of a truck witnessed an exceptional phenomenon that struck the city of make us normal. Man he was asleep not far from the point when he heard such loud strange noises that he thought it was an earthquake there are immortal fans that are all for. That that patrick rushed to the harbor like so many other people. And saw with his own eyes that it had been completely devastated ok last encourage me to get there faster see all of that. Aside from his descriptions of the destruction petrarca also wrote of hundreds of dead and dozens of sunken ships to mount royal rosie its obvious that these strange storm was a tsunami. It got got a level got norful think at that time petrarch could not have known that it was a tsunami because it was an unknown phenomenon in the middle ages arguably of. Today we are certain it was a tsunami. That want. To avoid a repeat of the catastrophe the vulcanologist has been searching for the cools of the tsunami that wrecked harbor in 1343 theres no. Record of a 14th century eruption of Mount Vesuvius in the gulf of naples. So now rosy has focused on another volcano located 200 kilometers from naples stromboli is one of the most active in the region. In 2002 an eruption caused a flank of the mountain to collapse into the sea a 10 metre high tidal wave reef to the island. The waves spread across the terrain in sea and much weakened reach the bay of naples. Who far more powerful eruption of strong belief have triggered the tsunami described by petrarch 700 years ago. Above the village of san vincenz oh on the slopes of the volcano archaeologists are a levy is excavating the remains of a small church shes provided now rosie with his 1st clues. Evan when i went to the magical we knew that a dramatic event led to the sudden collapse of the building probably a powerful earthquake because we found large blocks of stone inside on the church floor. Of evening. In order to date strong balis past activity archaeologists examined 3 skeletons found in the remains of the church. The skeleton was in a grave pit that was dug through the layer of collapsed tiles that fell down when the church collapsed so this person was definitely a witness of the catastrophe possibly a victim or possibly a survivor. The skeleton has been dated by carbon 14 in the middle of the 14th century. The date of the earthquake that shook the island of stromboli coincides with the tsunami disaster described by petrarch 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 from our own rules he began his own excavations he hopes to find clues linking the activity of the volcano to the tsunami described by petrarch in 1343. And 4 meters underground the vulcanologist finally discovered an intriguing mix of sedimentary deposits. Tsunami. This tsunami deposit has by far the largest we found. When we dated 821350 as evidenced by the materials and. They lock up much that ethos affordable look at the size of these perfectly round pebble stones they must have come from the beach. When the the presence of such a large sized elements proof of the tsunami was extraordinarily powerful. For the vulcanologist it all makes since the powerful wave that flushed these large pebbles 200 meters inland from the beach occurred at precisely the same time as the earthquake that destroyed the small Island Church there is a clear link between the eruption of the volcano and the tsunami. Its on the scene precede flank that all the volcanic material ejected by stromboli accumulates 700 years ago an eruption may well have sparked a landslide on the. Event. Would have hold many millions of tons of accumulated debris into the sea triggering the tsunami that reached the bay of naples but as we would maintain a strong warning given Strong Police current activity we believe the load of debris presently accumulated on the shuttle for call is comparable to levels of the time of the tsunami described by petrarch. From our own rosie the landslide caused by the 2019 eruption was just a harbinger of a much more serious disaster to come this hour adele full quote he says could collapse into the sea at any moment. And. The island of strong boley is under 24 hour surveillance to alert authorities residents and tourists in the event of danger. But what consequences would it tsunami have on a city the size of naples in a bottle of dark it you see our pool tsunami also probably near and these people are completely unaware that a tsunami from from bali could hit naples so yes i mean its a quandary phenomena. And in the case of rare natural phenomena well its too late then people tend to believe that there is no imminent danger since at sea all the kick is to see out. A Computer Generated model tracks the cools of the 1343 tsunami it gives an idea of what could be in store for one. Day but all this sort of going from you know the it would take under 30 minutes for the tsunami to reach the gulf of naples from stromboli or from the now only aim but. The devastation would be unimaginable Committee Really to think in buckets it could be the hour when all the boats in the harbor behind me would be hurled onto the streets speak the current. The water would gush into the subway and drown all of the passengers. The busy streets would be submerged. It would be apocalyptic. Scene but thats exactly what happens without an Early Warning system of these. Earthquakes landslides volcanic eruptions all of these natural phenomena can trigger tsunamis. Research carried out over the last 15 years has provided a better understanding of the threat its 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 tsunami science. Research is here feel they know exactly what will cause the next disaster. These images are from a government Awareness Raising Campaign broadcast in march 2808 aimed to prepare people for a tsunami that Scientists Say has an 80 percent probability of occurring within the next 3 decades. The 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 because a rupture of the one kind trough a 900 kilometer long ocean floor trench along japans west coast. Trough the threat of the 9th i trust is very specific because of the Economic Centers of japan whether tokyo or soka are not going. Or in all of our areas. Up. To date theres no technology that can predict earthquakes but japanese scientists have developed a Monitoring System to warn the public the moment a seismic wave is registered. He says i need to be able to detect movements as soon as possible and then issue a warning if thats what the darn it system does just right outside the pay of all suckers like. The dont it system is the most sophisticated seismic detector in the world 29. 00 small underwater observatories equipped with precious sensors and seismometers and excel or all matters are installed directly on the full blown off the coast of osaka it issues an alert with the very 1st tremor the tsunami. It would take 3 to 5 minutes for the tsunami to reach the 1st cities with waves 20 to 30 meters high they sweep into osaka bay and flood parts of or soka incog. The artificial islands would be the worst hit with waves of 3 to 5 meters after 30 to 45 minutes. To develop effective evacuation plans and tested protective walls the Disaster Prevention Center at Kyoto University simulates the effects of an earthquake you know pool. Were almost certain wed be dealing with a magnitude 9 earthquake. And that it would cause a tsunami. Us. Here at ease she has modeled the arrival of a wave with an average height of 20 meters thats the equivalent of a 6 Story Building in a city directly facing the noncontrolled. Sea walls would weaken the waves the impact the protective barriers would quickly become submerged under several meters of water. The simulations are supplemented by computer models theyve allowed to hear a team to predict the path and. Tsunami would take in tokyo they. Will blow its 5 kilometers inland the district around the Olympic Stadium could be buried under a 9 metre high wave simulation. Of where i got the use simulations are carried out to identify hazardous locations. For example a road that would flood quickly is not suitable as an evacuation route. To the entrances to many buildings would be blocked by water so they offer no shelter theres no then you get to a. Kyoto university has used these simulations to create an interactive evacuation plan in an emergency an app shows the progression of the waves and identifies the nearest safe zones. One idea that if we get information on our cell phones and on the internet is that same television stations also broadcast warnings with instructions on what to do to get to safety or security. Saving lives is key but scientists also want to minimize structural damage. The tsunami of 2011 once again showed that harbor areas are extremely dangerous places to be cheering and tsunami which transforms ships into giant projectiles. For hero turned on her she moto of Kobe University the harbor is a priority evacuation zone. At the state or osaka bay its very busy during the day. Just at any given time there are 30 to 50 boat sailing there. And we have no guarantee that in the event of a tsunami a situation that many have now. Experienced everyone would keep their cool and the ships would have accurate one after another in an orderly fashion. And thats why were developing an Intelligence System to evacuate ships automatically. Equate the origin though. Despite technological advances japan is seemingly living on borrowed time or sucka a city of 8000000 inhabitants and the countrys 2nd largest Economic Center is built on low lying flat lands its surrounded by hundreds of kilometers of protective walls. There are the 2011 earthquake weakened all the walls. Parts of the barrier collapsed so it wasnt offering effective protection before the tsunami arrived yes you need to this effort. To date even the most sophisticated technologies cannot predict earthquakes these artificial islands have apartment blocks Shopping Centers and petrochemical plants. Public education and Emergency Management can reduce the number of fatalities in the event of a tsunami. We often feel like weve tamed nature but time and again nature proves us wrong. Around the world Tsunami Research has made Great Strides but every new design step puts the technologies devised to protect us to a new test. If we build the bar blocks of hospitals public buildings houses in various buildings and. We are adding layers and layers of them every week and with daryn what were fighting. Around the world is that already or a beautiful disaster skipping greasing the. Waterfront leaving has an enduring appeal but the unchecked urbanization 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.
