authorities to investigate cost us in our lockers at the university of southern california and hermann fritz of the georgia institute of technology have arrived to conduct field research. quite impressive to see the devastation. there now 3 weeks after their end. everything can i say why it's important to come up as quickly as possible or at least once to emergencies over because a lot of bulldozing in this area already so a lot of evidence is very lost. the researches will be combing the debris for traces of the wave time is of the essence cleanup operations have already arranged valuable evidence and the monsoon rains a jew to start soon. working as a tsunami scientist is very much like being a detective on a crime scene there's a multiple murders have taken place and you really have to piece like in the bottle this sequence of events. they did tsunami hit 1st and this made the houses collapse or where they collapsed because of the earthquake or tsunami from the system or what were the people doing why is it that some people died and some people did well . the 2 researches want to determin

hermann fritz and he's indonesian colleague. returned to the west coast to gauge how one tsunami could have the region and to be in this sheltered area. paris city has received new footage that was filmed nearby . so there. so then you can see all. of these events and then this is when they started just last night. yeah a local landslide close i think triggered by the earthquake you have a semi-circle wave that you can even see in the video so i think this is going to be a localized impact and it is landslides and. you have a lot of aluminum with serious flooding once you should get it. to whom and for it's the low intensity of these 1st wave suggests it was triggered by a coastal landslide but that's alone doesn't explain what cools the tsunami that devastated the bank here we have evidence because we have a coast guard ok so the scar actually is along the shoreline. went into the ocean and so we have a coastal landslide i don't think there's localized tsunami is big enough to be the main source of the tsunami that wiped away o

in part constancio luckless and hermann fritz a continuing their research and tsunami early warning system was set up here after the 2004 disaster so why were there so many victims in 2018. you had to run out of vendors here selling food. it was really busy 1st we heard a rumble yeah but a good bit of. the people started screaming the water's rising. the so i 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 reg
