After an enormous earthquake struck central Mexico, horrifying photos of collapsed properties emerged and experienced numerous Los Angeles residents wanting to know if that can occur listed here. 1 qualified explained Sure. (KABC)
More than a long time, seismologists and structural engineers have received intensive knowledge about why some structures collapse while others continue being standing for the duration of an earthquake.
Los Angeles does have 1 benefit more than Mexico Town with regards to earthquake chance: Although the L.A. Basin is also fabricated from soft soils that amplify an earthquake’s shaking, it does so only by an element of five, compared with Mexico City’s element of 100, Jones mentioned.
