The graph below shows the number of 7+ quakes each decade.
Certainly looks like an increase in numbers since the 1990’s.

The following graph shows the number of 7+ events 1910-2011 on a yearly basis.
With another decade added it looks that the 1930’s, 1950’s and 1980’s were quieter compared to the other 4 decades.

These graphs will change as I complete more years going back.
