of course there are no deaths or injuries. but many buildings including this minaret are damaged. one day later. typhoon cameraman is the head of the earthquake risp management for the city he's faced with a big challenge there the city's warning system did not activate during the quake. you chose to that is sort of a key issue the you can say the system worked as it should have we have 10 stations at the moment but we aren't receiving a signal for many of them not even yesterday our task now is to build more stations and repair the 10 we already have shows with. turkey's conservative party ruled istanbul for 25 years until the summer of 2019 karr

a man says the party did not do enough to prepare the city for earthquakes something that the muslim fortunately we cannot say that istanbul is prepared for an earthquake today because i know there are still buildings here that are in danger of collapsing but they did it after all even the 5.8 magnitude quake caused major damage that it was still. the new city government wants to set a new priorities. today carmen hosts representatives from the mag to foundation and city hall for about 2 decades this group of scientists merchants and crafts people has been trying to prepare istanbul residents for the next big earthquake traumatized by the one $999.00 quake they do not want to leave their fate in the hands of the state alone you know our mission is that within the 1st 72 hours everyone is active in their own neighborhood she mom knows

we want to train $4.00 to $5.00 volunteers in each district to form a civilian disaster rescue team or. yes it's. the new city administration wants to work together with the foundation for disaster management expert. this is a ray of hope we have come to the right place he will support our projects develop them further and he also has plans of his own. the earthquake was a wake up call for the whole city. as a panel discussion the foundation mag informs residents about the dangers of earthquakes there's quite a bit of interest. tells them what they must avoid at all costs is panic. when combating a disaster the most important asset we have is people but only if those people are

prepared and can act reflexive. if they are not prepared then they become a liability. because they panic so they give plenty to take. the music. came home stamm gemini. during the barratry test seismologist marco bone hoff has a breakthrough. and yet he uses various types of stone to simulate test quakes. in the real world there might be $100.00 or 200 years between 2 strong quakes we don't have that time so instead we simulate these processes at an accelerated rate and we increase the pressure relatively quickly and then retrieve the measured values so we can do our calculations for let's list

alternately we can recreate a complete cycle from one quake to the next within a few minutes and often from. bono of tests to town with a sandstone sample. oppressed supplies an enormous amount of pressure to the stone . the machine similar taney asli registers acoustic signals that reveal what is happening to the stone internally. in the arab. world with slowly the machine increases the pressure on the stone it's as if 30 trucks were stacked up on one finger. on the surface it appears the stone hasn't changed but the acoustic signals on the monitor show another story. it's beginning to fracture more and more cracks become visible like small miniature quakes. 15 minutes later the stone breaks.

marco bornhorst says the same logic can be applied to large scale earthquakes. for them we're seeing all of this for shark activity before the point of fracture and since that similar for all rock samples we're hopeful that we can apply this method was with us in much income as a world just to so many many quakes to signal a larger earthquake is coming. was this also the case with the september quake in istanbul. scientists from all over the world conduct research at the german research center for geosciences in post in the hope of predicting when earthquakes will strike in addition to turkey greece and italy a 2 danger zones in europe the main trigger is the african plate which is pressing northwards towards the eurasian plate in the mediterranean. in 2016 an

earthquake rattled central italy nearly 300 people died one issue was the collapse of many old buildings this was not the case in japan which experienced a 9 point one magnitude earthquake in 2011. and nearly 20000 people died most from the resulting tsunami that slammed into the northeastern coast of the country devastating the area. researches say adapting infrastructure is crucial this is mchugh the earthquake that struck japan in 2011 is a good example indeed there was a lot of damage related to the tsunami but the buildings withstood due to compliance with earthquake resistant standards. japan

invests a lot of money in earthquake resistant construction for example offering subsidies for buildings with shock absorbing dampers. the money for this kind of technology isn't available in a stumble. 3 factors must be considered 1st the likelihood an earthquake will strike next 2nd all the number of buildings and maybe. a 3rd if you know the quality of the construction or how vulnerable the buildings are so a hotspot in other words a place where damage could be particularly great has these 3 factors and we see that in istanbul but also in cities like lima quito or mexico city. to mexico. the biggest challenge now in istanbul is limiting the potential damage of a mega earthquake. in the southwestern part of the

city the bucky neighborhood is particularly at risk. from the mag to foundation has what if a trophy is a disaster prevention coordinator. she surveys the area with. a seismologist. will look good if you want to get. the houses here are very old so it's imperative to push for change and rebuild. after the september quake 2 buildings were evacuated. the facade shows significant cracks. because those who go. downtown want. to go for the rich the residents are alone and upset. the oca's the few for taken

sick of your own luck one of the buildings will be rebuilt but the owners simply cannot agree on what to do with the other one. going to be most welcome. if a building is reported to the city is unsafe it should be torn down. but there's not enough funding to build a new. that's why unsafe buildings a still inhabited. goes to show number government only cares about prestige projects it doesn't care about how people really live but they should. get it from the it's not just about the quake itself it's the immediate aftermath be terrible the fire department wants fires to be ignited by natural gas. this is an aviation fuel tank and gasoline. and yet there is still no precautions stumble

on the finest that could occur after quite the biggest risk but instead. we have no time to lose but our government in ankara prefers to plan an absurd new canal through istanbul we must immediately prepare for a quake but they just aren't listening to us do it. all the. no other major city in europe has grown quite as fast in recent decades. and what is it lacking however earthquake resistant to residential buildings. in recent years the turkish government has repeatedly tightened building regulations. but the chamber of civil engineers is skeptical of the construction industry its chairman jamaal good to stress is that just because

a building is new doesn't mean it's safe from earthquakes. it's a major point. then study the title to brew a lot until very recently inspectors were chosen and paid by the builders themselves. how independently can you inspect the person who's paying you. at least since the 1st of january 29th teen inspectors in el selected through an electronic system where yet but even that does not suffice. because they're often not trained well enough they don't have special certificates so a simple diploma is enough to get the job we have a serious problem with construction supervision in this country yet they did the city is growing rapidly as a result it is becoming more and more crowded and the risks of severe consequences from an earthquake are increasing. that's the situation we're in right now it's

a crime isn't it can one really live in a city like this one not of the government these open spaces already they sure to be construction here it can't go on like this. meanwhile the state disaster management authority is raising awareness about the risks posed by earthquakes with an elaborately produced t.v. commercial. the message prepares the disaster so that your neighborhood stays safe how to go about this however is not specified instead the austerity promises educational campaign.

the reality on istanbul's street is not is a day like this the commercial in actuality there are constant traffic jams and more and more high rise. things. the new city government knows this all too well if he's seeking solutions and has invited german seismologist marco born hoff to istanbul. scientists from all over the world are joined by local rescue teams and associations to discuss the current situation. on house delivers the opening speech a sign of how much his work is appreciated the current knowledge of the marmara hold indicates a maximum expected earthquake magnitude of $7.00 of course this would not exclude a larger event as we have learned so dramatically in japan in 2011 but based on historical data this is probably

a solid measure. over the years boone halfs team has worked with turkey's disaster management austerity to set up 7 measuring stations in the mama region. quake safety is a top priority for the city's new mayor a crowd. he is in close discussion with bone hof and other international scientists their research will be incorporated into the new earthquake roadmap is stumble. i'm convinced this is an issue that the whole world must solve together. stumbled on. istanbul's biggest problem when it comes to worst quakes is the safety of its buildings nearly 50000 buildings are at risk even a mild quake can damage the huge if you live in a up with this poses a huge threat to the lives of tens of thousands of people presumably short of the

answer is not only to demolish houses and build new ones but perhaps to strengthen existing buildings as well you know in richland that we must use this time very wisely to find quick and practical solutions so we can save people's lives in sunderland john a quick thought of an. engineer is also committed to finding solutions but it's not working on predicting if an earthquake or a strike days or hours ahead of time he's focused on the seconds before the quake. you can alter their vision we developed an early warning mobile app the diluted uses about the stone earthquake in cities are starting to spot that you need to get off the questions of knowledge so we've proven the app works. i'm now here to get support for it from the city on the system in ny i don't wish to see to get in on this field on the chin. i play goodness appointment was put off until a later date. the

fear of the quake has been propelling him forward for years is stumble doesn't have an early warning system like the one in tokyo or mexico city so good clear took matters into his own hands and developed a mobile app in 2017. it's designed to send a warning signal to people in the istanbul area a few seconds before a major quake the app can be purchased for the equivalent of around 2 year as a year. so far has set up 6 measuring stations in the mama region using his own funds today he is monitoring his station in the beauty mentioned district. judge. the sensor registers tiny tremors 3 meters deep. and the event of an earthquake it measures the less powerful primary waves of the

quake it sends a signal to pieces 5 to 25 seconds before the stronger and more destructive secondary waves. the warning time increases the further you are from the earthquake's epicenter. is from trying to spot it stuff the system has proven itself but if there's only one station per location there's a risk of false alarms on all the cost reasons i've only set up $1.00 system at this course but it would be better to add one or even 2 stations every 3 kilometers and set up a whole network. but he doesn't have the funds for that each new station costs about $20.00. if i sounds and there's currently about 5000 people have downloaded his name. and he

a fraction in comparison to istanbul's 15000000 residents. but good now believes in what he's doing every 2nd counts. in 10 seconds you could take shelter with your children if you're driving a car you can park it safely if you're about to go inside a building or drive through a tunnel you decide against it you know these are seconds that save lives and you know. i. i love that seconds and not enough the german seismologist marco bone health he wants to be able to warn the population hours before a quake. he is out on the sea of marmara just off a stumble exactly where a full fall below the surface could trigger the next big quake.

on the island is known hoffa set up a measuring station to help with his forecasts. but the station is hardly sending any signals at the moment that's the problem. of the course this is the largest island off the coast of istanbul and these are pre-determined measurements sites because they're closer to the fault zone from. the team is headed to the highest point of the island. at. a summit in the middle of a nature reserve. here seismographs were installed 300 meters deep into the earth and covered with concrete. using acoustic signals they registered the smallest tremors that do not

reach the surface. this way even many earthquakes have recorded. the depths of the seismographs plays a critical role. we have to try to get beneath the surface because in a metropolitan area like istanbul there's a lot of background noise from infrastructure wind and weather that's bad for us because we want to measure the signals as cleanly as possible that's why we have to go deep below the surface but drilling deep down is expensive and we have to drill at least a few 100 meters so in this case a compromise between the cost of drilling and meeting our requirements is 300 meters deep. construction around 300000 euros was financed by the german research center for geosciences the turkish authority are fads and international donors. cherelle remembers how intensive the process was he said in the 2 most along with

the drilling here took a total of 9 months the ground is made from very hard stone so drilling into it was very difficult. it was also a mammoth task to bring these huge machines to the island. and then the drill heads of the machines kept breaking off. i think we had to replace 10 of them the drilling company hated us by the end of it all. the data from the seismographs dissenting almost real time via the internet to the disaster management also in ankara and to potsdam. well the team must now figure out why the signals a failing to send a u.s. company manufactures the senses they used in earthquake zones all over the world. technicians surge of venezuela has come all the way from the u.s. to help with maintenance we have some problems with the station seems like business and if they get to the central station so we thought of you know it was

a problem seems like it's the round digitizers has like a running site when it gets it will stop opposition because it's always decide because the seismographs are embedded deep underground they cannot be swapped out then and so can only activate them by remote control. economy and they didn't get here. on. moon have phones his colleagues imposed them to find out if the data has arrived from. them and we repair the data locker we know the data arrived in ankara and in 5 minutes we'll know if it arrived in parts but everything looks good. mission accomplished the data finally arrives in potsdam.

meanwhile app developer has found a backer for his early warning system a renowned stumble geologist wants to further develop his. jobs arbuckle professor genki alter rock wants to use cell phones to measure the shaking during an earthquake and compare it with the measurement data on site something like this is not been done before we want to combine these 2 functions in the until now it's not been possible to measure how each building reacts individually touring a quake but with cell phones lying around the house we could measure that. much. good claymates the geologists it is stumble technical university. they discuss how the app could be used to estimate damage after

a quake. a few years back geologist change tack who is also working on a warning system to predict earthquakes yeah yeah that's no longer his priority because he considers it dangerous. you know this that you just saw sort of if i could predict now that in 30 hours there will be an earthquake walk along how would they control the money in turkish banks who are sick of it would flee abroad thought about people would storm the banks they would storm the stores they would turn on each other that well are there sufficient security forces to prevent something like that is there a plan in place when you know there isn't it therefore even if there was a way to predict earthquakes our society would not be set up for it because then you would need 2 and a half square meters of space outside per person. but there is no space in istanbul we don't even have $75.00 square centimeters per person just go to the city center

the streets are 2 and a half meters wide the houses 6 stories high if one house collapses the whole street is blocked if fire breaks out in just one house it spreads to all of them been the young chicks. only a few months of passed since the last quake in istanbul on the 24th of january 2020 another earthquake strikes turkey. this time in the eastern part of the country. the quake is almost 30 times stronger than the september quake in $29.00 scene. at least 90 buildings collapse and 41 people died in the region. survivors and rescue workers brace overnight temperatures of minus 8 celsius. emergency units travel from istanbul the rescue work takes days.

geophysicist marco bone half doesn't have much time left unfortunately that's exactly what research requires. but he does have new findings the results of the september quake or in. his thesis seems to be correct. under the sea of marmara many many quakes accumulated until the big quake with a 5.8 magnitude struck. and the big question is whether these fractures the foreshocks are signs of a larger earthquake. research is don't yet know if this is a pattern that can be applied to all quakes but the indications are growing soon have estimates that it will take another one to 2 years to see if the method is proved correct. only then will it be possible to develop

a reliable forecasting system. best best case scenario would be to put out a sort of fever curve where every day we could estimate that there's a higher or lower risk of an earthquake and residents would start to adjust to this it would be like what we see with forecasting extreme weather this is not yet the case with earthquakes and there's a long road ahead to get there but this is what we're aiming for and we're working to improve this situation systems of our best on. the people of istanbul only have a real challenge has its priorities a set. as quake resistant buildings. public mourning seconds before a quake. and a full cost. the researches were cremains
