Seismicity Report for Northern California,
for the three week period of 
December 14, 1995 - Jan 3, 1996

(Note:  This report includes seismicity data recorded by the Northern     
        California Seismic Network in Menlo Park during the period of 
        the federal furlough.  It does not include data for the rest 
        of the United States and the World that is typically made 
        available by the USGS National Earthquake Information Center. 
        Regular weekly reports will resume with the January 4-10 summary. 

San Francisco Bay Area
     
    Seismicity in the Bay Area during the 3-week hiatus was typical for
the most part with small clusters on the creeping San Andreas and along
the central Calaveras.  The Calaveras was most active with half a dozen
M2-3 events east of Gilroy (#3/1), aftershocks to a M3.9 on December 12.
The largest Calaveras earthquake however occurred just this past Friday
about six miles northeast of Morgan Hill (#9/1).  No reports were received
that any of these Calaveras earthquakes were felt.  
   The San Andreas experienced its usual small cluster near San Juan
Bautista (#7/1). The largest event in this cluster was a M3.3 event on
Christmas Eve that may have been felt locally.  More interesting was a
trio of small events on the peninsula San Andreas near Portola Valley
(#2/1).  The Portola Valley area has proved to be the most active area
along the otherwise "locked" peninsula segment.  In the past 25 years
about a dozen M3 earthquakes have occurred here, nearly half during a
small swarm in June, 1975.  
   Other events of interest were a M2.0 northwest of Pacifica (#4/1), a
M2.2 northwest of Orinda (#8/1), and a M1.8 beneath San Pablo Bay
northwest of Point Pinole (#6/1).

Northern & Central California
	
   After more than a year of sporadic aftershocks, the Markleeville area
returned to center stage with a pair of M5 earthquakes that were widely
felt throughout the Tahoe Basin, as far west as Sacramento, and as far
south as Fresno (#6/2).  These moderate earthquakes occurred in the same
general area as a M6.0 in September, 1994.  
   Activity in the Cape Mendocino area consisted of five events larger
than M2 along the Mendocino fracture zone, the largest a M3.4 on December
14 (#1/2).  Three more M2 events occurred parallel to the north coast west
and south of Eureka.  Four deep earthquakes occurred beneath the Klamath
Mountains during the three week hiatus, all presumably related to
subduction of the Gorda Plate.  Beginning with a pair of 29-km-deep M2.6
events on December 15 (#2/2) activity continued with a 27-km-deep M2.5
event on December 24 (#7/2) and a 44-km-deep M2.8 on January 3 (#9/2).  
   Notable activity in the central Coast Range included a pair of M3's at
the Geysers geothermal area (#3/2), a M3.1 near Lake Berryessa (#8/), a
M2.0 on the southern Maacama fault west of Lakeport, and a pair of M2
events on the Bartlett Springs fault north of Clear Lake.      

Long Valley Caldera

   Two clusters of M2 earthquakes occurred within the caldera during the
reporting period.  Early on December 19 five M2 events occurred just two
miles southeast of Mammoth Lakes (#3/3).  All five occurred in a short,
12-minute burst that trailed out with about as many M1 events over the
next 1-2 hours.  None were reported to have been felt in Mammoth Lakes. 
On December 30 a pair of M2 events occurred along the south rim of the
calderas southwest of the airport (#5/3).  They were followed two days
later by a M2.5 about one mile farther east.
   The main activity south of the caldera were a pair of M3 events
southwest of Mt. Morrison (#6/3).

Notes for Table 1:
       Origin time in the list is in GMT, in the text and on maps
       it is in local time.
       N RD: is the number of readings used to locate the event.
       N S: is the number of S waves in N RD.
       RMS SEC: is the root mean squared residual misfit for the
                location is seconds, the lower the better, over 0.3
                to 0.5 seconds is getting bad, but this is machine,
                not hand timed, data.
       ERH: is the estimated horizontal error in kilometers.
       ERZ: is the estimated vertical error in kilometers.
       N FM: is the number of readings used to compute the magnitude.
       REMKS: obtuse region codes that denote the velocity model
              used to locate the event.
       DUR MAG: is the magnitude as determined from the duration of
                the seismograms, not the amplitude.  Sort of like
                going to echo canyon and measuring how loud your
                yell is by counting echos.
       FIG: denotes the figure/event number in the maps posted separately.
