What us state gets most earthquakes?

Although California is the most notorious for earthquakes, Alaska actually has the most per year, due to its large volcanic activity in the Aleutian Islands. Many other western states have large amounts of earthquakes as well. Regions of Arizona and Nevada bordering California have many earthquakes, as well as Washington and Oregon. Rocky Mountain states such as Wyoming, Idaho and Montana tend to have many earthquakes, although mostly minor (1-3.0 Richter scale) in size. Their activity is caused by the Yellowstone Supervolcano which feeds many of the parks' geysers and basins.


How many earthquakes are there per day in the US?

According to the U.S. Geological Survey (USGS) National Earthquake Center there are over a million earthquakes each year around the world. Only a portion of these are recorded (~20 - 30K per year) because most occur over remote areas or in the ocean.Between 2000 and 2011 the average number of earthquakes in just the US was 3,820 per year that are magnitude 2.5 or higher, which is on average 10.5 per day. But as with most earthquakes, most of these are in rural areas and not even felt.For magnitude 7 and higher there is on average 1 every 2 years in the US typically in Alaska, California or Hawaii.


Why do strong earthquakes occur where there have been many recent earthquakes?

I can't really say in detail .....but it is most likely that its because there is a default in that area ....like in California ..there are several defaults there and thousands of earthquakes occur each day there. BECAUSE its a active earthquake zone." :D Earthquakes also occur in Alaska and also; off the coast of Mexico....
