Seismicity Report for Northern California,
the Nation, and the World for the week of
January 18 - 24, 1996

San Francisco Bay Area    
    
     The past week was very quiet.  During the seven-day period ending at
midnight on Wednesday, January 24, 1996 the U.S. Geological Survey office
in Menlo Park recorded only 10 earthquakes of magnitude one (M1) and
greater within the San Francisco Bay area shown in Figure 1.  Only one was
as large as M2.  This total compares to 18 earthquakes during the previous
seven-day period (January 11 - 17), four of which were as large as M2.0. 
   The lone M2 earthquake was a M2.9 Saturday afternoon that occurred
along the creeping segment of the San Andreas fault about three miles
southeast of San Juan Bautista (#1 in figure 1).  Other activity on the
San Andreas was limited to a M1.7 on the creeping segment, southeast of
Saturday's event and three M1's along the Loma Prieta segment east of
Santa Cruz.  The Calaveras fault was equally quiet with just four M1
events, none larger than M1.3.
   One earthquake of note occurred in the North Bay area:  a M1.9 that
occurred Tuesday evening along the Rogers Creek fault about six miles
northeast of Novato (#2/1).  
   
Northern & Central California
	
  Two areas in northern California that have not experienced earthquakes
recently were active during the past week.  The first was in the eastern
Coast Range about 35 miles southwest of Red Bluff (#4/2). Three
earthquakes, all of similar magnitude, occurred here last Friday morning. 
Though all were large enough to have been felt, none were reported, owing
perhaps to the remoteness of the area.  The most recent comparable
activity here was a small cluster in May of last year that included one
M3, one M4.2, and numerous M2 events.  The second active area was about
nine miles northwest of Lassen Peak, near the small community of Viola
(#2/2).  The activity consisted of a trio of M2's last Thursday night
followed by another pair of M2's on Saturday afternoon.  The last event on
Saturday was the largest, a M2.8 that apparently went unfelt along with
the others.  The Viola area was the location of a similar cluster of small
earthquakes in October, 1983.
   The Cape Mendocino area was a bit more active than in recent weeks with 
  four M2+ events, the largest a M3.3 late Tuesday afternoon that was
located nine miles northwest of Petrolia (#8/2).  To the north a trio of
M2's occurred early in the week south and east of Eureka (#3/2).   
  Other activity of note in the north state:  continued aftershocks in the
Markleeville area, the largest a M3.0 (#1/2), a pair of M2's north of Lake
Berryessa (#5/2), and a M2.7 in the northern Sierra NEvada about 16 miles
northwest of Reno, NV (#7/2). 

Long Valley Caldera

  A trio of M2 earthquakes occurred beneath the southern rim of the
caldera during the week (#1/3).  All occurred within a 3-hour period last
Saturday morning and were located just southwest of the airport.  None
were reported to have been felt.
   Activity in the Sierra Nevada block south of the caldera was limited to
a pair of M2's, the first and largest a M2.8 Tuesday evening southwest of
Mt. Morrison (#2/3). 

USA Seismicity (January 14 - 22)
  
   Data provided by the National Earthquake Information Center showed only
one notable earthquake in the lower 48 states, outside of California,
during the past week.  This M3.4 temblor occurred Sunday morning along the
western Cascade Range east of Seattle (#3/4).  It was felt in the towns of
Fall City and North Bend.  
   A trio of M4's (or so) occurred along the Blanco Fracture zone off the
coast of central Oregon, too distant to be felt onshore (#1/4).  
   A pair of M3.1 events in southern California were felt locally in the
Big Bear Lake and Yucca Valley areas (#2/4). 
   Domestic earthquakes outside of the contiguous U.S. included a M4.3
along the Kenai Peninsula in southern Alaska that was felt strongly at
Soldona (#1/5) and a M4.5 on the island of Hawaii that was felt at Waimea,
Wikoloa, Glenwood, and Laupahoehoe (#4/5).

The Planet Earth  (January 14 - 22)

   Only two earthquakes on the planet were as large as M6:  a Mb6.0 near
the north coast of Paua New Guinea (#5/5) and a Ms6.0 in the south
Sandwich Islands region (#6/5).  Felt earthquakes include a Mb5.8 near the
coast of Peru that was felt at Barranca Chimbote, and at Lima (#3/5) and a
Mb4.8 on the Colombia-Equador border that was felt in the Quito, Ecuador
area (#2/5).

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.
