Seismicity Report for Northern California,
the Nation, and the World for the week of
   April 28 - May 4, 1994

   During the seven-day period ending at midnight on Wednesday, May 4,
1994 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.  However, only two of these were as large as M2. 
This total compares to 17 earthquakes during the previous seven-day period
(April 21 - 27), three of which were as large as M2.
   Though the number of earthquakes in the region was up slightly, none
were large enough to have been felt.  The largest earthquake during the
week was a M2.2 in the East Bay late Tuesday night.  It was located
beneath the town of Alamo, about three miles north of Danville (#2 in
figure 1).  A slightly smaller M2.1 occurred earlier in the week along the
creeping segment of the San Andreas about two miles south of San Juan
Bautista (#1/1).  The creeping segment was a bit more active than it has
been in recent weeks with nearly a dozen other earthquakes, all smaller
than M2.  
                      
Northern & Central California

  The Gorda Plate region was the most seismically active area during the
past week, producing a trio of M3's and several smaller earthquakes. 
Activity began with a M2.4 last Thursday in the southern Gorda Plate about
44 miles west of Eureka (#1/2).  The following Monday two M3.3 earthquakes
occurred in the Gorda Plate about 100 miles west of the coast.   There
were several events long the southern margin of the plate beginning with a
M2.5 last Friday evening (#3/2), a M2.9 early Tuesday morning (#6/2), and
a small cluster of events near the cape, the largest a M3.0 late Wednesday
afternoon (#7/2).  
   The only other M3 earthquakes in northern & central California occurred
just after noon last Thursday in the southern Cascade Range about 13 miles
northeast of Lassen Peak (#2/2).  Both events locate just west of the
southern end of the Hat Creek fault, near the point where the fault
becomes buried beneath lava flows from West Prospect Peak.  These are the
largest earthquakes seen in this area since close monitoring of the Lassen
Peak area began in 1981.  
    Other events in northern California include a pair of small M2's north
of Clear Lake and a M2.2 just northwest of Lake Berryessa.  Central
California was very quiet except for a pair of small M2's on the creeping
segment of the San Andreas.  Seismicity along the eastern Sierra Nevada
consisted of a pair of M2's along the state border southeast of Lake Tahoe
(#4/2), a M2.3 east of Mono Lake (#8/2), and a M2.0 about 30 miles
southwest of Lone Pine.
     
Long Valley Caldera
     
    For the second straight week there were no earthquakes as large as M2
inside the caldera.  The lone M2 earthquake in the area was a M2.6 Tuesday
night that occurred southeast of Mt. Morrison (#1/3).

USA Seismicity (April 24 - May 5)
  
  According to data provided by the National Earthquake Information
Center, at least a couple states outside of California experienced notable
earthquakes during the past week.  A M2.8 in north-central Oklahoma was
felt by residents of Drummond and Enid (#3/4).  Eastern Idaho continued to
experience small aftershocks, the largest a M3.4 early last Friday morning
(#4/4).  Aftershocks also continued in southern California with activity
in both the Northridge (#2/4) and Landers areas.  A M3.3 off the southern
coast of Oregon (#5/4) was part of the Gorda Plate activity discussed
above in the Northern California section.  The largest earthquake in the
region was a M4.3 offshore of Vancouver Island, British Columbia (#1/4).

The Planet Earth  (April 24 - May 5)
   
    The largest earthquakes during the week were both centered in the
Hindu Kush region of south-central Asia.  The first was a Ms6.3 in
northern Afghanistan that was felt strongly at Termiz and as far away as
Tashkent, Usbekistan (#3/5).  It was followed later the same day by a
Ms6.2 in Tajikistan (#4/5).  Only slightly smaller were a Mb5.9 in the
Santiago Del Estero province of north-central Argentina (#1/5) and a Ms5.9
along the southwest coast of Sumatera, Indonesia (#5/5).  Two moderate
earthquakes are worth noting:  a Mb5.6 in Kyushu, Japan that was felt at
Miyazaki, Kagoshima, Kumamoto, and Oita (#2/5) and a Mb5.6 beneath
southeastern Iceland (#6/5).

Notes: 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.
