Seismicity Report for Northern California,
the Nation, and the World for the week of
   January 20 - 26, 1994

San Francisco Bay Area    

   For the second week in a row no earthquakes as large as M2.0 occurred
in the Bay Area. For the seven-day period ending at midnight on Wednesday,
January 26, 1994 the U.S. Geological Survey office in Menlo Park recorded
16 earthquakes of magnitude one (M1) and greater within the San Francisco
Bay area shown in Figure 1.  This total compares to 20 earthquakes during
the previous seven-day period (Jan. 13 - 19), none of which were larger
than M1.9.  
   
Northern & Central California

   Overall, seismicity remained low throughout most of the region.  The
largest earthquake was a M4.2 off Cape Mendocino, an area that otherwise
saw only one other event as large as M2 (#1 in figure 2).  The most recent
earthquake of comparable size was a M4.2 in early August, 1993.  To the
south the Coast Range was quiet following last week's series of M2's along
the Maacama fault.  The only notable activity was a continuation of M2
events north of Lake Berryessa (#7/2), aftershocks to a M4.1 on Jan. 17th.
   The only activity south of the Bay Area occurred along the San Andreas. 
The creeping segment produced several M2 earthquakes during the week, the
largest a M2.9 early Sunday morning about 3 miles northwest of San Benito
(#6/2).  Southeast of here, M2.0 earthquakes occurred both at the south
end of the creeping segment and at the northern end of the Parkfield
segment (#5/2).   
   The only other activity of note were a trio of M2 earthquakes in
northern California.  Last Thursday a M2.6 occurred in the Basin and Range
terrane of northeastern California, about 39 miles south-southwest of
Alturas (#2/2).  This is the largest earthquake recorded in this region in
at least the past three years.  The following day a M2.7 occurred in the
Stephens Pass area east of Mt. Shasta (#3/2), an area that experienced
several M4's during a swarm in August,1978.  Finally, on Saturday
afternoon, a M2.0 occurred just southeast of McCloud, a small town nestled
near the southern base of Mt. Shasta (#4/2).    
  
Long Valley Caldera
   
    Activity remained fairly low in the caldera with only four earthquakes
as large as M2.  The largest of these was a M2.4 early Monday afternoon
that was located about two miles southeast of Mammoth Lakes (#2/3).  
Somewhat surprisingly, this earthquake was reported to have been felt by
some residents in the town. 
    Activity was a bit higher south of the caldera with a M3.0 south of
Mt. Morrison (#4/3), a M2.8 on the southern Hilton Creek fault (#5/3), and
a pair of M2.9 earthquakes in the volcanic tableland nine miles northwest
of Bishop (#6/3).  

USA Seismicity (January 18 - 25)
  
    Aftershocks to last week's M6.6 Northridge earthquake continue to
roll through the San Fernando Valley north of Los Angeles.  According to
data provided by the National Earthquake Information Center the largest of
this reporting period was a M5.0 early last Wednesday afternoon (#2/4).  
Over a dozen M4 aftershocks occurred during the week, the largest a M4.6
late last Friday morning.  Seismologists from the Southern California
Seismic Network have noted that although "the aftershock sequence is
slightly more energetic than average, [it] is decaying slightly more
quickly than average".  They expect the sequence to produce about one more
M5.0 or larger aftershock during the next 12 months.  The probability of
it occurring within the coming week is about 20% (1 in 5).  Readers
interested in obtaining additional information on the Northridge
earthquake, call (818)395-6326 to request a copy of the Weekly Earthquake
Report for Southern California.
   Other domestic quakes of note:  a M4.5 on the Blanco Fracture Zone off
the southern Oregon coast (#1/4); several aftershocks in the Klamath Falls
area including a M4.1 last Wednesday afternoon (#3/4); a M3.3 in
north-central Nebraska that was felt in many of the communities
surrounding the epicenter (#4/4).  According the NEIC, earthquakes have
struck this general area of South Dakota and Nebraska in the past,
sometimes causing minor damage.  The most recent example was a M4.4 event
in March, 1983 that caused some damage in the Fort Thompson-Stephan area
east of Pierre, South Dakota.

The Planet Earth  (January 19 - 25)

   One major earthquake occurred during the past week, a Ms7.3 near
Halmahera Island, the northernmost of the large Moluccas Islands in the
central Indonesian archipelago (#3/5).  The earthquake killed at least
seven people, injured 50, and destroyed scores of buildings.  Two other
strong earthquakes also struck Indonesia during the week including a Ms6.9
in the Irian Jaya region (#1/5) and a Mb6.2 off the southern coast of
southern Sumatera (#4/5).  
   Other moderate earthquakes of note include a Mb5.8 beneath northern
Peru (#2/5), a Mb5.1 beneath Ecuador (#5/5), and a Ms5.8 beneath the
northern mid-Atlantic ridge (#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.
