This event appears to be consistent with other low magnitude events  
that  have occurred to the Southwest of Tucson, AZ.  I have seen other  
events that are similar, and no information was ever posted on them.   
I noticed the event was visible across the lower 48 states, and  
southern Alaska.  It is most likely less than M 4.0 as that is the  
USGS minimum cutoff for display of information on international events.
