Seismicity Report for Northern California,
the Nation, and the World for the week of
August 1 - 7, 1996

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

     
San Francisco Bay Area   

   Activity remained light throughout the Bay Area.  During the seven-day
period ending at midnight on August 7, 1996 the U.S. Geological Survey
office in Menlo Park recorded 15 earthquakes of magnitude one (M1) and
greater within the San Francisco Bay area shown in Figure 1.  Four were as
large as M2.  This total compares to 18 earthquakes during the previous
eight-day period (July 24 - 31), five of which were as large as M2.
   The San Andreas fault was the source of three of the four M2 events. 
The first of these occurred early last Thursday morning just north of Loma
Prieta Mountain in the Santa Cruz Mountains (#1/1).   It was followed
early Friday morning by a M2.1 along the creeping segment of the San
Andreas, about 13 miles southeast of Hollister (#2/1), and by another M2.1
just after noon on Saturday that was located just southeast of San Juan
Bautista (#3/1).  
   The week's largest earthquake was a M2.8 events that occurred Wednesday
afternoon on the central Calaveras fault in eastern San Jose (#4/1).
   
Northern & Central California
	
   The week was relatively quiet throughout the region with only one
earthquake as large as M3, a M3.5 that occurred along the Mendocino
fracture zone about 18 miles west of Petrolia, an area that had seen two
M2 events earlier in the week (#1/2).  To the north a M2.2 event occurred
along the coast just three miles southwest of Eureka (#10/2).  
    The Coast Ranges were quiet at the M2 level except at the Geysers
geothermal area where five M2 events occurred over the course of the week. 
Two  M2 earthquakes were also recorded in the northern Sacramento Valley,
a M2.1 about 12 miles northeast of Willows (#2/2) and a M2.1 beneath the
Lake Shasta area northeast of Redding (#9/2).   
   Activity in the Sierra Nevada range included a pair of small M2's
beneath Lake Almanor about five miles southeast of Chester (#4/2), a pair
of M2's east of Markleeville (#6/2), and M2.1's west of Carson City Nevada
and southwest of South Lake Tahoe (#3/2).
   Central California experienced three small M2's along the central
creeping segment of the San Andreas.  The central Valley saw a M2.6
northwest of Coalinga (#7/2) and a M2.2 about 12 miles east of Avenal. 
Finally, a M2.3 occurred along the Big Sur coast about 13 miles northwest
of San Simeon (#8/2). 

Long Valley Caldera

    Activity in the caldera continued along the southwest side of the
resurgent dome, just east of the town of Mammoth Lakes (#2/3).  Of the
four M2 quakes that occurred during the week, the two largest were only
M2.2 and none were reported to have been felt locally.  
   Activity south of the caldera saw a pair of M2 events near Mt. Baldwin
(#1,#4/3), a M2.1 beneath Mt. Morrison (#3/3), and a M2.0 beneath the
north slope of Laurel Mountain (#5/3).    

USA Seismicity (July 29 - August 7)
  
   The largest earthquake in the lower 48 states was a M4.3 in east-
central Idaho that was felt in the towns of Challis and Salmon (#4/4). 
Also felt were a pair of M3 earthquakes that occurred just east of the
southern Colorado town of Trinidad (#2/4) and a M3.3 earthquake in the
northern Willamette Valley that was felt at Estacada, Lebanon, Sandy, and
Silverton, Oregon (#3/4).  Probably felt, though we've received no felt
reports, was a M3.5 in western Nevada north of the town of Fallon (#6/4). 
Other domestic quakes of note include a pair of felt events north of the
San Fernando Valley (#5/4) and a M3.2 Gorda Plate earthquake off the coast
of northern California/southern Oregon (#1/4).  

The Planet Earth  (July 29 - August 7)

   The southwestern Pacific was far and away the most active area on the
planet with a major earthquake (M7.1) in the Solomon Islands region that
was felt at Gorontalo and Tolitoli (#2/5) and a trio of moderate to large
earthquakes along the Tonga trench.   Of the latter events, the largest
were a Ms6.7 in the Tonga Islands (#4/5) and a Mb6.5 just southeast of the
Fiji Islands at a depth of over 500 km (#6/5). A Ms5.9 near the coast of
Ecuador was felt in Guayas and Manabi Provinces (#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.
