Seismicity Report for Northern California,
the Nation, and the World for the week of
January 15 - 21, 1998

 Stephen R. Walter
U.S. Geological Survey
345 Middlefield Rd.  MS-977, Menlo Park, CA  94025

     
San Francisco Bay Are   

    During the seven-day period ending at midnight on Wednesday,
January 21, 1998 the U.S. Geological Survey office in Menlo Park
recorded 19 earthquakes of magnitude one (M1) and greater within
the San Francisco Bay area shown in Figure 1.  Three were as large
as M2.0.  This total compares to 29 earthquakes during the prior
seven-day period (January 8 - 14), eight of which were as large as
M2.  
   The first of the M2 events occurred early last Saturday morning
on the northern Hayward fault beneath the Oakland Hills (#1/1). 
No felt reports were received for this earthquake.   A M1.6
occurred Wednesday afternoon farther north on the fault beneath
the Berkeley Hills.  
   The other two M2 events occurred in the southern Bay Area, the
first on the San Andreas fault about five miles northwest of San
Juan Bautista (#2/1), the second on the Qien Sabe fault five
miles east of Hollister (#3/1).
   
   
Northern & Central California
	
   A minor earthquake  last Thursday was felt in much of the
northern Lake Tahoe area. The M3.7 event occurred Thursday morning
about seven miles north of Truckee and was reported felt aid Tahoe
City and Truckee, California and in Carson City, Reno, and Sparks,
Nevada (#1/2).  The earthquake occurred along the Mohawk Valley
seismic trend that extends from Lake Tahoe north to the Lake
Almanor/Lassen Peak area.  The most recent comparable earthquake
in this area was a M3.1 that occurred in July, 1994.
   In contrast, a M4.1 off the coast of Cape Mendocino on Tuesday
morning was apparently not felt locally (#4/2).  At a distance of
30 miles west of Petrolia, it was apparently too far offshore to
produce noticeable shaking at the coast.  It was followed six
hours later by a M2.7 aftershock and preceded four days earlier by
a M2.4 event just 14 miles west of Petrolia.  
  Other earthquakes of note in the north state included a M2.4
Monday evening about four miles south of Eureka (#6/2).  The Coast
Ranges were quiet at the M2 level with the exception of the
Geysers geothermal area where a dozen events as large as M2
occurred during the week, the largest a M3.0 on Sunday morning
(#2/2).
  Central California experienced a pair of M2 events at the
southern end of the creeping segment of the San Andreas about 12
miles northwest of Parkfield (#3/2). This is the third week in a
row that this section of the fault has been active at the M2
level.  Pairs of M2 events also occurred in the Coalinga area
(#7/2) and in the southern Owens Valley about 23 miles south of
Lone Pine (#5/2).

Long Valley Caldera

  Seismicity in the caldera declined to its lowest level in nearly
two months, since the resurgence of activity along the south side
of the caldera began on November 22.  During the past week only 18
earthquakes occurred in the caldera that were as large as M2.0. 
Only two of these were as large as M3.  This compares to the
previous week when 75 M>2 earthquakes occurred, nine of which were
as large as M3.  Activity again was focussed primarily in two
areas:  the area six miles east of Mammoth Lakes near the Mammoth
Lakes airport (#2/3) and the area about two miles east of Mammoth
Lakes near the highway 395 junction (#1/3).  

USA Seismicity (January 12 - 20)
  
   The National Earthquake Information Center reported only one
notable earthquake in the lower 48 states outside of California. 
This M3.0 event occurred east of Challis, Idaho.  It is not known
if this event was felt by local residents.   A M3.1 in the San
Fernando Valley was felt by residents of Pacoima (#2/4).  This was
apparently an aftershock of the 1994 M6.7 Northridge earthquake.

The Planet Earth  (January 12 - 20)

   There were no large earthquakes on the planet during the week. 
 Felt events included a M5.0 near the east coat of Honshu, Japan
that felt as far away as Tokyo and Yokohama (#2/5), a M5.1 in the
Fox Islands of the Aleutian archipelago that was strongly felt at
Akutan, a M4.9 along the coast of north Chile that was felt at
Copiapo and Tierra Amarilla, and a M5.7 in the Kurila Islands that
was felt in eastern Hokkaido, Japan (#6/5).

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.
