But a similar megaquake could cause “collapses of substantial-rises at fairly huge distances with the fault,” Jones mentioned.

They also deliver the feeling of rolling motion, like The sort you might come to feel on a ship. Lengthy objects, such as tall structures, are specially vulnerable to this kind of rolling, shaking movement.

Miyamoto mentioned the kinds of properties that have collapsed in Mexico Metropolis are what structural engineers would expect: brick constructions together with brittle concrete buildings, Particularly Individuals with weak first flooring. Shots of many of the collapsed structures are made of brittle concrete, Miyamoto said.
