Re: BAJA CALIFORNIA, MEXICO AftershocksThank you, Bob.  Yes, I have seen 
that other URL, but not in this case.  I was just amazed by the number 
listed, as you say, above 2.5.  Even the ANDREANOF ISLANDS, ALEUTIAN IS., 
ALASKA complex does not seem to have this many.

As usual, I was just curious!

Best regards,
Jerry

Jerry -

The problem is the ability to see all of the aftershocks normally generated 
by a seismic event.  On the header of the site most of us use to view 
various events world wide, it states:

Latest Earthquakes Magnitude 2.5 or Greater in the United States and 
Adjacent Areas and Magnitude 4.0 or Greater in the Rest of the World - Last 
7 days

You can see events down to M 2.5 on this list because the Baja events were 
adjacent to Southern California.  If you go to the map of California and 
Nevada that shows recent event, and then click on one pf the squares that 
show the recent Baja events, you will find the following link near the 
bottom of the page:

List of Earthquakes on this Map (with MAP)

This link will give you a much more complete list of events, some even less 
that M 1.0

The variable is having access to the information on all the aftershocks.
