San Francisco Bay Area  
    
    Activity picked up moderately during the past week in the Bay Area. 
For the 7-day period ending at midnight on Wednesday, March 10, 1993 the
U.S. Geological Survey office in Menlo Park recorded 30 earthquakes of
magnitude one (M1) and greater within the San Francisco Bay area shown in
Figure 1.  Seven of these were as large as M2.0.  This total compares to
17 earthquakes that were recorded during the previous 7-day period, two
 of which were as large as M2. It is the highest weekly total since the
third week of January when a total of 32 earthquakes were recorded in the
area. 
    Part of the increase was due to activity in two areas that only
occasionally produce earthquakes.  The Concord fault produced a pair of M2
earthquakes on Sunday, neither of which was reported to have been felt, 
(#1 in figure 1).  The Concord fault hasn't produced a M2 since late
November of last year.  Similarly, the San Andreas fault zone off the
Golden Gate produced a pair of earthquakes during the week, the largest a
M2.5 on Tuesday 4 miles northwest of Pacifica (#3,#4/1).  
    The San Andreas was otherwise largely quiet with only a pair of M1's
at the northern end of the Loma Prieta rupture zone and a trio of small
earthquakes on the creeping segment.  The largest of these was a M2.2 on
Tuesday afternoon about 14 miles southeast of Hollister (#5/1).
   The central and southern Calaveras fault was active at about the same
level as during the previous week.  A M2.5 occurred about 7 miles
northeast of Morgan Hill Monday morning (#2/1) with a M2.9 following on
Wednesday morning about the same distance north of the town (#7/1). 
Earlier Wednesday, a M2.5 occurred along the southern Calaveras, about 4
miles southeast of Hollister (#6/1).  
   
  
       
Northern California

   The largest earthquake in the state during the past week was a M3.4
event early last Friday morning at the Geysers geothermal area (#1/2). 
This was the only earthquake in the state larger than M3.0 and the second
week in a row that the Geysers has led the list.   
   Elsewhere in the region things remained fairly quiet with, if anything,
fewer than usual M2 events.  A quick rundown of these  generally unfelt
temblors follows.  There were four M2's in the Cape Mendocino area, the
largest a M2.6 about 18 miles southwest of Eureka (#2,#3/2).  In the north
Coast Range the only activity of note, aside from the Geysers' event
mentioned above, was a M2.2 about 23 miles north of Willits (#7/2).   The
southern Cascades and Sierra Nevada produced no earthquakes as large as
M2.  The creeping segment of the San Andreas south of the Bay Area was
slightly more active than usual with four M2 earthquakes recorded; however
the largest of these was only a M2.3 (#6/2).  Finally, a M2.4 occurred in
the southern Coast Range about 9 miles west-northwest of Paso Robles
(#4/2).
  
Long Valley Caldera
    
    For the third straight week the south moat area of the caldera
continued to be active.  While most the dozen or so recorded earthquakes
were smaller than M2, there was one M3.0 event early Tuesday morning that
was located 3 miles east-southeast of Mammoth Lakes.  The last M3 in the
caldera was a M3.4 at the end of January in roughly the same area as
Tuesday's event.  
    For the first time in over a year there were no earthquakes as large
as M1.5 located in the Sierran terrane south of the caldera.
    
USA Seismicity

    According to data provided by the National Earthquake Information
Center (NEIC) during the past week there was only one notable earthquake
in the lower 48 states, outside of California.  Mid-morning on Wednesday,
a M2.5 occurred in the northern Chesapeake Bay region about 10 miles
south of Baltimore (#4/4).    
            
The Planet Earth
 
   The largest earthquake in the world during the past week was a Ms7.1 in
the Santa Cruz Islands region of the southwest Pacific; it was followed by
a numerous moderate aftershocks, including a pair of M6's (#3/5).  This is
the first M7 earthquake on the planet so far this year and the first since
a pair of M7's occurred in the southern Indonesian archipelago in mid-
December of last year.  M6 earthquakes were also more numerous in the past
week than they have been in several months.  They included a Ms6.7 south
of the Fiji Islands (#4/5),  a Ms6.1 west of MacQuarie Island (#5/5), and
a pair of M6's in the south Sandwich Islands of the southern Atlantic
Ocean (#6/5).  Other earthquakes of note include a Ms5.0 in the Greenland
Sea (#1/5), a Ms5.0 in southern Greece (#2/5), and a pair of M5's in the
northern Gulf of California (#2/4).

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.
