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.
