27 earthquakes have happened from 1995 to 2008.
5-6 recorded earthquakes have measured 9.0 or higher on the Richter scale. 1960 Valdivia earthquake; Valdivia, Chile; 9.5 magnitude 1964 Alaska earthquake; Prince William Sound, Alaska, USA; 9.2 magnitude 2004 Indian Ocean earthquake; Indian Ocean, Sumatra, Indonesia; 9.1-9.3 magnitude 1952 Kamchatka earthquakes; Kamchatka, Russia (then USSR); 9.0 magnitude 2011 Tohoku earthquake; Pacific Ocean, Tohoku region, Japan; 9.0 magnitude 1833 Sumatra earthquake; Sumatra, Indonesia; 8.8-9.2 magnitude (est.)
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.
The weakest earthquake recorded is usually referred to as a microearthquake, which typically has a magnitude below 2.0 on the Richter scale. These earthquakes are often not felt by humans and are mainly detected by seismographs.
Lots and lots of earthquakes are happening every day, but many of these are too small, or hit in an unpopulated area, to be counted. However. there are about 70 strong registered earthquakes a year
In the world there are approximately 53,139 earthquakes per year of magnitude 3.0 or greater which equates to an average of 145.6 per day. Major earthquakes of 6.0 or greater happen at the rate of 1 every 2.5 days.
