Is Recent Earthquake Activity Unusual? Scientists Say No.

Even with six major earthquakes striking in the first four months of this year scientists say 2010 is not showing signs of unusually high earthquake activity.

Some years have had as few as 6, as in 1986 and 1989, while 1943 had 32, with considerable variability from year to year.
