Since the government is back "in business" I was able to do a historical search. The link above should take you to that search showing the quake history in the area.

The new USGS pages may be difficult for some, but here's one of the advantages. All aspects of the view and/or search are in the URL, therefore it can be shared as a link. The full link is pretty nasty, though. :)
