Which country has the most earthquakes?

The answer to this question is not as straightforward as it may seem. In order to most accurately answer it, we will rephrase the question four different ways: 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...

Which state has the most damaging earthquakes? The most natural (non-manmade) earthquakes?

California has the most damaging earthquakes, and Alaska and California have the most natural (non-manmade) earthquakes. Find information about earthquakes in each state on our Earthquake Information by Region website (scroll down).

Where do earthquakes occur?

Earthquakes can strike any location at any time. But history shows they occur in the same general patterns year after year, principally in three large zones of the earth. The world's greatest earthquake belt, the circum-Pacific seismic belt , is found along the rim of the Pacific Ocean, where about 81 percent of the world's largest earthquakes...
