How To Earthquake-Proof A House

this is the world's largest earthquake simulator it's called e defense its huge Shake table can support a 10 story building and then move it in all directions with the force of the world's most destructive earthquakes e defense has conducted more than a 100 tests subjecting all kinds of buildings to different simulated earthquakes all to learn how to make buildings more earthquake resistant part of this video was brought to you by Shopify more about them later in the video on the 17th of January 1995 at 5:46 in the morning an earthquake struck the city of coob Japan it took Everyone by surprise Japan is one of the most seismically active countries in the world it sits on the boundary of four tectonic plates and 90% of all earthquakes and almost all of the powerful ones happen at tectonic plate boundaries but coob isn't near one this earthquake was caused by an interplate fault essentially a crack in the Earth's surface that isn't at the boundary of a tectonic plate this fault hadn't produced any earthquakes for around a thous years so the city was completely unprepared the hiest for the Quake measured a magnitude 6.9 just under the definition of a major earthquake despite this the earthquake killed more than 6,000 people and left another 300,000 homeless more than 80% of the fatalities were caused by the collapse of buildings the total economic cost was estimated at80 billion US in response the government gathered scientists for a conference on earthquake disaster prevention and there they agreed to build the largest earthquake Simulator the world had ever seen so I sent Peter to Japan for an exclusive look inside this facility so we're entering the world's biggest earthquake simulator as they're about to do an experiment so let's go right now there's eight concrete walls that they're going to feed seismic signals into the shake table and they're going to see which ones are the most sturdy so the seismic data that they're going to feed in is from the El Centro earthquake which was an earthquake that happened on the 18th of May 1940 it was a 6.9 magnetude earthquake and it's one of the first ones that we actually have seismic data from okay things are wow wow wow wow wow wow wow oh oh okay it's it's it's just really cool to see such ...
