Seismicity Report for Northern California,
the Nation, and the World for the week of
  September 1 - 7, 1994

San Francisco Bay Area    
    
  For the seven-day period ending at midnight on Wednesday, September 7,
1994 the U.S. Geological Survey office in Menlo Park recorded 25
earthquakes of magnitude one (M1) and greater within the San Francisco Bay
area shown in Figure 1. Of these, nine were large as M2.0, including a
M4.1 along the west side of the San Joaquin Valley on Wednesday.  This
total compares to 23 earthquakes during the previous seven-day period
(August 25 - 31), four of which were as large as M2.
  The most notable activity during the week was a M4.1 Wednesday
afternoon that occurred about 17 miles southwest of Modesto and was felt
in the Modesto area (#7/1).  The epicenter of the quake lies close to the
northwest-trending  San Joaquin fault, which marks the western side of the
San Joaquin Valley from west of Tracy to the Newman area.  The focal
mechanism for the mainshock indicated a thrust earthquake along a
northwest-trending fault.  Five aftershocks occurred within the following
12 hours, two of which were as large as M2.    
  Four M2 earthquakes occurred within a 14-hour period last Thursday. 
This is a significant increase in activity compared to recent weeks when
four M2's over the course of a week would have been considered active. 
The four events occurred in separate areas of the East and South Bay
beginning about 2:30am with a M2.0 eleven miles southeast of Antioch
(#1/1).  Ten hours later a M2.9 occurred on the central Calaveras about
seven miles northeast of Morgan Hill (#2/1).  This was followed two hours
later, around 3:00pm, by a M2.1 on the southern Sargent fault three miles
southwest of Gilroy (#3/1).  Just after 4pm a M2.1 occurred on the
central Calaveras about 12 miles north of Morgan Hill (#4/1).   
   Two more M2 events occurred over the weekend.  The first was again on
the Calaveras, a M2.3 Saturday evening that was located about seven miles
east of Milpitas (#5/1).  The following afternoon, a M2.5 occurred west of
the San Andreas about seven miles southeast of San Juan Bautista (#6/1).  
    	

Northern & Central California
	
   We have recorded over 80 aftershocks (M>2.0) to last Thursday's M7.0
earthquake on the Mendocino Transform fault (#2/2).  Thirty of the
aftershocks were larger than M3.0 and two were as large as M4.0.  Because
the seismicity is occurring nearly 100 miles offshore, many of the smaller
aftershocks will not be recorded well enough to be located.  In fact, the
locations of even the largest aftershocks should be considered very
preliminary; uncertainties in the velocity models used in locating the
earthquakes may have introduced errors in epicenters of several tens of
miles.  (see last week's report for a discussion of the mainshock and
first 12 hours of aftershocks).  
   There was only minor seismicity in other parts of northern California
during the week.  A M2.6 subduction event occurred just west of Eureka
last Thursday (#4/2) and a  M2.5 occurred about 30 miles southeast of
Petrolia early Wednesday morning.  The only activity in the Coast Ranges,
aside from a few M2's at the Geysers, was a M2.1 Tuesday evening about 23
miles northeast of Willits.  Northeastern California saw a bit more
activity with a M2.8 last Thursday morning along the south side of Lake
Tahoe (#1/2), a M2.6 north of the lake on Sunday morning (#6/2), and a
M2.3 south of Lake Almanor on Wednesday (#8/2).    
   The central part of the state was a bit more active than usual with a
pair of M3's in the Parkfield/Coalinga area.  The first of these was a
M3.2 Tuesday morning about ten miles west of Coalinga (#7/2).  It was
followed the next day by a M3.2 on the Parkfield segment of the San
Andreas (#9/2).  To the northwest of Parkfield the creeping segment of the
San Andreas was also active earlier in the week with a pair of M2.5's
about ten miles southeast of Tres Pinos (#3/2).  

Long Valley Caldera

   There were no earthquakes as large as M2 within the caldera during the
week.  The only notable activity was a 2.4 on the Hilton Creek fault
southeast of the caldera (#1/3).

USA Seismicity (August 30 - September 7)

   According the data provided by the National Earthquake Information
Center, there were several notable earthquakes in the lower 48 states
outside of California.  Most interesting was a M3.4 last Friday in central
Michigan that was felt most strongly in the Lansing area and, to a lesser
extent, at Grand Haven, Grand Rapids, and Jackson (#3/4).  In contrast, a
M4.3 on Monday in a remote area of southern Utah was not widely reported
at all.  Other domestic events of interest include a M3.2 and a M2.9 in
southern Nevada (#1/4)and a M2.9 in southeastern Idaho (#2/4).

The Planet Earth  (August 30 - September 7)

   The largest earthquake during the week was the M7.0 Mendocino Transform
event (#1/5 and #2/2).   Though widely felt throughout northern California
and southern Oregon, it produced little damage because of it's location
about 100 miles offshore.  In contrast a much smaller M5.8 in the
northwest Balkans injured several people and caused some damage in the
Bitola area of the former Yugoslav Republic of Macedonia (#2/5).   A M5.3
offshore of Chignik, Alaska was strongly felt at Chignik and Perryville
but produced little or no damage (#5/5).  Other events of note include a
Ms6.2 in the Vanuatu Islands (#4/5), a Mb6.0 east of the Kuril Islands
(#6/5), and a Mb5.7 in the Eastern Island region (#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.
