	This document is a commentary on current seismic activity.  The 
	earthquakes discussed have been detected and processed 
	automatically.  All epicenters and magnitudes have been reviewed 
	to exclude obvious blunders; however, they must still be 
	considered preliminary.  For further information, please contact 
	the authors or the Caltech Public Relations Office at (818) 395-6326.

			--------------------------------

	This week's Report covers the time period from midnight Tuesday
	morning, November 23, Pacific Standard Time, to midnight Wednesday
	night, December 1, Pacific Standard Time.  This is a longer week
	than usual because of the Thanksgiving holiday.  The map includes a 
	virtually complete set of earthquakes of M2.0 or larger, plus many 
	smaller ones that happen to have made it through the data processing.
	There are 378 this time.
		It was yet another uneventful week, the largest quake being
	only M3.2.  Two small earthquakes were reported felt, both of them
	M2.7's; the table speaks for itself.
		The table lists the quakes that were M2.0 or larger in
	the central part of the coverage area.  Only M2.5 and larger events 
	are listed for south of the U.S./Mexico border, and for the
	Coalinga/Parkfield area.  For more information on the latter, see
	the Northern California Report issued by the U.S.G.S. in Menlo 
	Park.  Times are local times; if you want Greenwich Mean Time, 
	add 8 hrs, to the Pacific Standard Time listed.

	Figure. A map of southern California showing the earthquakes 
	recorded during the past week by the Caltech/USGS Seismic 
	Network.  Major faults are marked, as well as the metropolitan 
	areas of Los Angeles (L.A.), Palm Springs (P.S.), San Diego 
	(S.D.), and Santa Barbara (S.B.).  The circles denote the 
	earthquakes, the size of the circle indicating the magnitude.
