Has there ever been a 10 earthquake?

No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. … The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles long…a “megaquake” in its own right.

What country has the most earthquakes?

For which country do we locate the most earthquakes? Japan. The whole country is in a very active seismic area, and they have the densest seismic network in the world, so they are able to record many earthquakes.

What size earthquake would destroy the earth?

Magnitude Earthquake Effects Estimated Number Each Year
6.1 to 6.9 May cause a lot of damage in very populated areas. 100
7.0 to 7.9 Major earthquake. Serious damage. 20
8.0 or greater Great earthquake. Can totally destroy communities near the epicenter. One every 5 to 10 years

How far away can a 9.0 earthquake be felt?

In a place with complex geology, every rock contact scatters and absorbs seismic energy, so that far away you’d probably feel it but not see damage or casualties. In the U.S. Midcontinent, with layer-cake geology that makes efficient wave guides, a 9.0 event would probably produce appreciable damage 565 miles away.

Is a magnitude 13 earthquake possible?

Originally Answered: How much damage would a magnitude 13 earthquake do? It’s not physically possible. That amount of energy could only be released by the absolute destruction of the planet.

Where is the biggest fault line in the United States?
