416 earthquakes in 30 days!

[John Olexa]

Good grief!! There have been 416 earthquakes magnitude 4.0 or greater in the world in just the last 30 days. 12 in just the last 2 days!

There are some 15,000 Quakes above 4.0 each year.

So that 400 in a month is below the typical average by a little, but not massively so considering many 4 pointers in the deep oceans are probably missed.
