Seismicity Report for Northern California,
the Nation, and the World for the week of
October 3 - 9, 1996

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

     
San Francisco Bay Area   

  During the seven-day period ending at midnight on October 9, 1996 the
U.S. Geological Survey office in Menlo Park recorded 29 earthquakes of
magnitude one (M1) and greater within the San Francisco Bay area shown in
Figure 1.  Seven were as large as M2.  This total compares to 20
earthquakes during the previous seven-day period (September 26 - October
2), three of which were as large as M2.
   The increased number of M2 earthquakes was due to a small cluster of
events on the creeping segment of the San Andreas fault about three miles
south of San Juan Bautista, six of which were as large as M2 (#1/1).  Two
occurred last Thursday morning, three more on Monday night, and the final
event on Tuesday evening.  None were reported to have been felt although
those larger than M2.5 may well have been.    The only other notable
earthquake occurred last Thursday evening on the Marsh Creek Fault about
five miles southwest of Brentwood (#2/1).  It was followed by a slightly
smaller M1.9 in the same location on Monday evening.
   
   
Northern & Central California
	
   It was a relatively quiet week in the region, the exception being a
M4.2 that occurred in western Nevada about 22 miles south of Tonopah
Junction (#8/2).  Otherwise the largest earthquake in northern & central
California was a M3.0 on the creeping segment of the San Andreas near the
Pinnacles National Monument (#5/2).   Northern California was equally
quiet with less than half a dozen M2's along the Mendocino fracture zone,
the largest a M2.8 early Sunday morning (#2/2).  A pair of 23-km-deep
subduction zone events occurred onshore of Cape Mendocino, the first about
22 miles southeast of Fortuna (#1/2), the second about 30 miles north of
Hayfork (#7/2).  The Coast Range experienced a pair of M2's along the
Maacama fault, the largest a M2.4 on Sunday morning that was located
about eight miles southeast of Laytonville (#6/2).  A similar sized event
occurred earlier that morning on the Green Valley fault about 12 miles
west of Winters (#4/2).
   Activity in the eastern Sierra Nevada was limited to four M2's about 17
miles north of Truckee (#9/2) and a M2.3 just south of Lake Almanor
(#3/2).   

Long Valley Caldera

   Only one M2 earthquake occurred within the caldera during the week, a
M2.0 early Tuesday morning that was located about one mile southeast of
Casa Diablo Hot Springs (#3/3).  South of the caldera five small M2 events
occurred near Lake Dorothy (#2/3) and a M2.08 occurred northeast of Mt.
Morrison (#1/3). 

USA Seismicity (September 30 - October 10)
  
   The largest earthquakes in the region during the past week occurred off
the west  coast.  Last Thursday and Friday a pair of M4 earthquakes
occurred along the Blanco fracture zone west of the central Oregon coast
(#1/4).  On Saturday a M6.0 earthquake rocked offshore of Vancouver
Island, about 230 miles west of Vancouver, British Columbia (#6/4).  It
was followed within 24 hours by three aftershocks as large as M4, the
largest a M5.2 aftershock that followed the mainshock by half an hour.  
   Other domestic quakes of note include the M4.2 western Nevada quake
discussed above (#5/4, #8/2), a M3.2 Northridge aftershock (#2/4), and a
M3.1 southeast of the Salton Sea (#4/4).

The Planet Earth  (September 30 - October 10)

   The largest earthquake on the planet was a M6.8 in the eastern
Mediterranean Sea, just south of the Island of Cyprus (#6/5).  The
earthquake was strongly felt in Cyprus, Israel, Lebanon, Turkey, Egypt,
and Syria.  One fatality was reported in both Cyprus and Egypt and several
injuries were reported in Cyprus.  
   Moderate earthquakes of note included a M5.5 near the east coast of
Kamchatka (#1/5), a M5.3 in the western Caribbean Sea (#2/5), and M5
events on both the Southwest and Southeast Indian Ridges (#3,#5/5).

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.
