        NOTICE:  Next week's report will come one day early and
                 will cover the 6-day period from March 9 - 14.

San Francisco Bay Area    
    
   Another fairly quiet week in the Bay Area.  During the seven-day period
ending at midnight on Wednesday, March 8, 1995 the U.S. Geological Survey
office in Menlo Park recorded 26 earthquakes of magnitude one (M1) and
greater within the San Francisco Bay area shown in Figure 1.  Only four of
these were as large as M2.0.  This total compares to 28 earthquakes during
the previous seven-day period (February 23 - March 1) four of which were
as large as M2. 
   Both the creeping segment of the San Andreas and the central Calaveras
fault were active at the M2 level this week.  Two M2 events occurred
along the San Andreas south of San Juan Bautista last Thursday and
Saturday (#1 & #2 in figure 1).  Then on Tuesday morning a M3.1 occurred
along the Calaveras about nine miles north of Morgan Hill (#3/1).  It was
followed an hour later by a M2.7 farther north along the Calaveras about
nine miles southeast of Milpitas (#4/1). 
   The only other earthquakes of note during the week were a M1.6 on the
central Hayward fault beneath northeastern San Leandro and a M1.6 beneath
Alamo, near the southern end of the Concord fault. 
        
Northern & Central California
	
   The region was relatively quiet during the past week with most of the
earthquake activity located in the northern Coast Ranges and offshore of
Cape Mendocino. The southeast Clear Lake area, site of a M4.0 on February
28, experienced five aftershocks as large as M2.0 (#1/2).  The Bartlett
Springs fault north of Clear Lake also became active last Thursday/Friday 
with four M2 earthquakes (#2/2).    
   The Mendocino fracture zone again was the most seismically active
region in the state with six earthquakes as large as M3.0.  The most
active area was about 75 miles offshore of Cape Mendocino, close to the
epicenter of a M6.6 quake that rocked the north state on February 18
(#3/2).  A M3.1 occurred 50 miles west of the Cape Saturday afternoon
(#6/2) and a M3.3 occurred later that night just eleven miles west of
Petrolia (#7/2).  Onshore activity was limited to a pair of M2 events
southeast of Eureka (#4/2).  With focal depths over 20 kilometers these
were likely related to movements within the down-going Gorda Plate.  

Long Valley Caldera

   A pair of M4 earthquakes occurred just south of the rim of the caldera
and about a mile east of Convict Lake (#1/3).  The earthquakes occurred
Saturday afternoon and evening and were felt in Mammoth Lakes and Bishop.
Activity began with a M4.4 just after 4:00pm.  It was followed 25 minutes
lager by a M2.0 aftershock.  The second M4 event occur just before 7:00pm
and was followed five minutes later by a M2.8 and a M3.8 aftershock.  The
M4 events are the largest earthquakes in the Long Valley area since a
M4.5 occurred near Red Slate Mountain on August 10, 1993.  

USA Seismicity (February 27 - March 8)
  
   The National Earthquake Information Center reported several notable
earthquakes in the lower 48 states outside of California.  Perhaps the
most intriguing was a M3.0 in northern New York state, about 15 miles west
of Lake Placid (#2/4).  Occasional small (M<4) earthquakes have been
observed in the Lake Placid area in the past two decades, part of a broad
swath of seismicity that extends from southern New Jersey north along the
Hudson River Valley and into eastern Ontario and southern Quebec.  This
zone includes a number of moderate-sized earthquakes, including a M5.9
that struck the Massena, NY area in September, 1944.
   Activity in the west was a bit more prosaic with ongoing activity in
the Soda Springs area of southeastern Idaho (#3/4) and a M3.5 in the Basin
& Range terrane of western Nevada (#4/4).  Southern California was
reasonably quiet with only one earthquake large enough to get people's
attention:  a M3.7 offshore of Santa Monica that was felt in western Los
Angeles (#1/4). 

The Planet Earth  (February 27 - March 8)

 A relatively small earthquake turned out to be quite destructive.  A
Mb4.5 event occurred along the Colombia-Equador border last Saturday,
killing at least seven people and damaging many homes in the Colombian
city of Pasto (#3/5).  A slightly larger earthquake occurred near the
southwestern coast of Turkey but apparently produced no injury or damage
(#5/5).  It was widely felt in the Dodecanese Islands of Kalimnos, Kos,
and Rodhos, as well as in the Mugla area of Turkey.  
  The largest earthquake of the week was a Ms6.2 that occurred east of the
Leeward Islands (#6/5).  Again, no damage was reported though the
earthquake was felt on the islands of Guadeloupe, Martinique, St. Lucia,
and Dominica.  Other events of note include a Mb4.3 in the northern Yukon
Territory (#1/5), a Ms5.7 in the Samoa Islands region (#2/5), and a Ms5.8
near the east coast of Borneo in the Celebes Sea (#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.
