Seismicity Report for Northern California,
the Nation, and the World for the week of
February 8 - 14, 1996

 Stephen R. Walter
U.S. Geological Survey
345 Middlefield Rd.  MS-977, Menlo Park, CA  94025

San Francisco Bay Area    
    
  Another quiet week in the Bay Area.  During the seven-day period ending
at midnight on Wednesday, February 14, 1996 the U.S. Geological Survey
office in Menlo Park recorded 11 earthquakes of magnitude one (M1) and
greater within the San Francisco Bay area shown in Figure 1.  Five were as
large as M2.  This total compares to 22 earthquakes during the previous
seven-day period (February 1 -7), two of which was as large as M2.0. 
  All the M2+ activity occurred on the creeping segment of the San
Andreas beginning with a pair of M2's 12 miles southeast of Hollister
(#1/1) and ending with a M2.9 and a M3.1 eight miles southeast of
Watsonville (#4/1).  The Calaveras fault was almost entirely quiet at the
M1 level and above.
  Two events in the North Bay, though small, are worth mentioning. On
Monday a M1.6 occurred on the southern Rogers Creek fault about six miles
northeast of Novato (#3/1).  Early Wednesday morning a M1.5 occurred on
the San Andreas fault just offshore of Pacifica.	
   
Northern & Central California
	
   It was a relatively quiet week with only one earthquake as large as
M3, aside from the M3.1 near Watsonville discussed above.  This M3.1 event
occurred early Wednesday morning in the Cape Mendocino area, about 13
miles northeast of Petrolia (#8/2). It was preceded early Tuesday morning
by a M2.9 beneath the coast about 13 miles southwest of Eureka.  
  Central California was also quiet with several M2's on the creeping San
Andreas north of the Pinnacles (#3/2), a M2.0 near San Ardo (#5/2), and a
M2.5 five miles northeast of Coalinga (#7/2).  Ditto with the eastern
Sierra Nevada where the only notable activity was in the Long Valley
caldera (see below).  Otherwise it was quiet with single M2's southeast of
Lone Pine (#1/2), northwest of Bishop (#4/2), east of Markleeville (#9/2),
and east of Quincy (#6/2). The latter earthquake was an aftershock to a
M3.9 that rocked this area on February 1st.  
    

Long Valley Caldera

   As the graph in Figure 3 shows, there was a sharp increase in activity
in the Mammoth Lakes area during the past week with over 40 earthquakes
larger than 1.5.  This increase was caused by a resurgence in activity on
the south side of the caldera about one mile south of the airport, an area
that had been active at the M2 level for the past three weeks (#1/3).  The
activity began last Friday with numerous very small events. It wasn't
until Monday that any were as large as M2. Activity continued at the rate
of105 to 30 events per hour through Tuesday, though many events were too
small to be located.  The activity slowed markedly on Wednesday before
resuming again in the late afternoon.  Activity continued into Thursday
with two M3 shocks.  The largest, a M3.6, was probably felt in Mammoth
Lakes.      

USA Seismicity (February 4 - 14)
  
   The National Earthquake Information Center reported no earthquakes of
note in the lower 48 states outside of California.  However they did
report several moderate events on the Blanco Fracture zone about 100 miles
off the coast of Oregon (#1/4). Notable earthquakes in southern California
included a M3.7 that was felt at Yucca Valley (#2/4) and a M2.9 that was
felt at Upland (#3/4).

The Planet Earth  (February 4 - 14)

   There were no earthquakes as large as M6 on the planet during the past
week.  The two largest shocks were a pair of M5.9's, the first offshore of
the central Kuril Island (#5/5), the second near the southern Izu Islands
south of Honshu, Japan (#6/5).  Only slightly smaller were a M5.8 in
eastern New Guinea (#3/5) and a M5.7 south of Sumbawa, Indonesia (#4/5).

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.
