	This week's Report covers the time period from midnight Thursday
	morning, July 27, Pacific Daylight Time, to midnight 
	Wednesday night, August 2, 1995, Pacific Daylight Time.  We 
	recorded 237 earthquakes of during the 7-day period covered.
		The only quake felt this week, and the only one above
	M3 occurred just after midnight on Friday morning: M3.6, located
	near Anza in the San Jacinto Fault zone.  It was felt in the
	epicentral area and also as far away as Pasadena by one insomniac 
	(namely me).  The focal mechanism was strike-slip, consistent 
	with San Jacinto activity.
		The table lists the quakes this week that were M2.0 or 
	larger in the central part of the coverage area.  Times are local 
	times; if you want Greenwich Mean Time, add 7 hrs to the Pacific 
	Daylight Time or 8 hrs to the Pacific Standard Time listed.
