Seismicity Report for Northern California, 
the Nation, and the World for the week of
March 14 - 20, 1996

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

San Francisco Bay Area

   Seismicity was relatively low throughout most of the Bay
Area, the exception being an active cluster on the creeping San
Andreas south of Hollister.  During the seven-day period ending
at midnight on Wednesday, March 20, 1996 the U.S. Geological
Survey office in Menlo Park recorded 32 earthquakes of magnitude
one (M1) and greater within the San Francisco Bay area shown in
Figure 1.  Eleven were as large as M2 including four M3 events
southeast of Hollister.  This total compares to 32 earthquakes
during the previous seven -day period (March 7 - 13), five of
which were as large as M2.0   
  Three of the four M3 earthquakes on the creeping segment
occurred early Saturday morning about 12 miles southeast of
Hollister (#3/1).   The fourth and largest event occurred late
Tuesday night and, like the others, was probably felt locally. 
This segment of the San Andreas routinely experiences
earthquakes of this magnitude, most recently on January 14 and
November 24.                  
 Other events of note in the SouthBay included a M2.0 on the Calaveras 
(#5/1) and a M2.1 on theQuien Sabe fault (#2/1).  The central Bay
Area was relatively quiet with the largest earthquake being a M2.6 
in the northern Diablo Range about eight miles southeast of Livemore 
(#4/1).  M2.1 earthquakes occurred on the central Calaveras fault east of
Milpitas (#1/1) and along the San Gregorio fault about 12 miles
west of Santa Cruz (#6/1).  A slightly smaller M2.0 occurred on
the central Hayward fault just east of Alameda (#7/1).  

Northern & Central California

    Only two earthquakes as large as M2 occurred in the Cape
Mendocino area during the week:  a M2.0 early Tuesday about 20
miles northeast of Petrolia (#7/2) and a M2.9 Wednesday evening
on the Mendocino fracture zone about 20 miles west of Petrolia
(#9/2).    The Coast Range was equally quiet with a M2.0 on the
Maacama fault about nine miles north of Ukiah (#2/2) and a M2.0
on the Rogers Creek fault just three miles west of Glen Ellen
(#9/2). 

     Activity in central California was limited to the creeping
segment of the San Andreas.  In addition to the four M3 events
southeast of Hollister (discussed above), there were a pair of
M2's north of  Pinnacles National Monument on Monday afternoon
and evening (#5/2).  

      The  east side of the Sierra Nevada saw one M2 aftershock
in the Markleeville area (#4/2), a M2 in the eastern Mono Basin
(#1/2), and a M2.4 about 20 miles southwest of Bishop (#6/2).  

Long Valley Caldera

     Three  felt M3 earthquakes occurred within the caldera
Saturday evening,  part of an active cluster that was located 1
to 2 miles east of Mammoth Lakes (#1/3).   This activity began
last Wednesday (see last week's report), becoming most active
late Saturday afternoon and evening.  As  this activity began to
decline, two other areas in the caldera experienced some minor
activity:   a pair of M2's east of the airport (#4/3) and a M2.7
beneath Mammoth Mountain about two miles west of Mammoth Lakes
(#5/3).    

USA Seismicity (March 12 - 20)

    The National Earthquake Information Center reported several
domestic earthquakes of note.  Of most concern was an earthquake
swarm beneath the  Akutan  volcano in the eastern Aleutian
Islands (#2/5).  At the height of the activity last Thursday,
residents of Akutan reported feeling earthquakes every several
minutes.    Seismicity has declined to several felt events per
day since the weekend.  Seismologists monitoring the earthquakes
believe they are caused by magma moving within the volcano and
have warned of a chance that the volcano could erupt.   
    Minor earthquakes occurred within the lower 48 states
outside of California.:  a M 2.8 in eastern Idaho (#1/4) and a
M2.9  in central New Mexico (#3/4).  Canada however experienced
several moderate events during the week including a M4.1 in
eastern Ontario that was felt in the Montreal and Ottawa areas
(#2/4) and a Mb5.1 near the west coast of Vancouver Island
(#4/4).  

The Planet Earth (March 12 - 20)

    A Ms6.0 earthquake along the Kyrgyzstan-Xinjiang border
killed at least 26 people  and destroyed over 1500 homes in
Jiashi County in westernmost China (#5/5).   At least 10,000
people were left homeless and forced to seek shelter from the
cold in tents.
    Other moderate to large earthquakes on the planet included a
pair of M5's near the coast of Oaxaca, Mexico that were felt in
Mexico City (#6/5), a Ms6.0 in eastern Papua New Guinea (#4/5),
and a Mb5.9 south of Honshu, Japan (#3/5).

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.
