Seismicity Report for Northern California,
the Nation, and the World for the week of
June 26 - July 2, 1997

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

     

San Francisco Bay Area        
          
 
   The Bay Area remained quiet with only one event in the area as
large as M2.0.  During the seven-day period ending at midnight on
Wednesday, July 2, 1997 the U.S. Geological Survey office in Menlo
Park recorded 12 earthquakes of magnitude one (M1) and greater
within the San Francisco Bay area shown in Figure 1.    This total
compares to 23 earthquakes during the prior seven-day period (June
19 - 25), only one of which was as large as M2.
  The lone M2 earthquake was a M2.7 that occurred around noon on
Tuesday along the creeping segment of the San Andreas about three
miles west of San Juan Bautista (#2/1).  The only other event of
note was a M1.9 last Thursday night offshore of the Marin
headlands, about five miles southeast of Bolinas (#1/1). 
   
Northern & Central California
	
    Thee week's largest earthquakes both occurred along the
Mendocino fracture zone.  The first, a M3.1 last Thursday night,
occurred about 20 miles northwest of Petrolia (#1/2).  A slightly
larger M3.4 occurred early Tuesday morning was located 68 miles
west of Petrolia (#7/2).  The only other earthquake as large as M3
in the region was a M3.0 in western Nevada about 30 miles
northeast of Fallon (#3/2).  
   Other events of note in northern California included a pair of
M2's south of Lake Pillsbury (#6/2), a M2.6 at the Geysers
geothermal area, and a M2.1 15 miles northeast of Red Bluff
(#8/2).  
   Activity in central California included a M2.5 on the offshore
area about 38 miles west of Carmel (#2/2) and a M2.0 along the
coast about 8 miles northwest of San Simeon (#4/2).  The Sierra
Nevada range was quiet with only a few events as large as M2.0:  a
M2.1 east of Markleeville, a 26-km-deep M2.3 about 19 miles north
of Visalia (#5/2),m and a M2.7 six miles southeast of Lake
Isabella (#9/2).     

Long Valley Caldera

  Early Monday morning a M2.0 occurred beneath the south side of
the caldera, about one mile south of Mammoth Lakes (#4/3).  South
of the caldera half a dozen earthquakes occurred that were larger
than M2.0, the largest a M3.0 last Thursday evening that was
located about two miles east of Mt. Hopkins (#1/3).  A pair of
M2's occurred beneath Mt. Baldwin (#2/3) and a trio of M2's
occurred about a mile northwest of Mt. Morrison (#3/3).

USA Seismicity (June 25 - July 2)
  
   A number of small to moderate earthquakes occurred in the
country during the past week according to data provided by the
National Earthquake Information Center.  The largest was a M5.3 on
the island of Hawaii that was felt throughout the island and
caused power outages at Hilo (#4/5).  On the mainland a M3.7
occurred early Friday morning beneath western Puget Sound, WA, an
aftershock to a M4.9 on four days earlier (#3/4).  The
Yellowstone area was shaken by a M3.8 early Saturday afternoon
(#6/4) and a rockburst at the Lucky Friday mine near Mullan, Idaho
had an energy release equivalent to a M3.1 earthquake (#5/4). 
Southern California experienced five earthquakes as large as M3
including a M3.7 that was felt at Lake Isabella (#4/4) and a M4.1
five miles northwest of San Bernardino that was felt at Colton,
Rialto,San Bernardino, and in the San Bernardino Mountains (#7/4). 

The Planet Earth  (June 25 - July 2)

   The planet was relatively quiet during the week with only one
event that qualified as "large":  a M6.0 on the southern East
Pacific Rise last Thursday (#2/5).  On the other hand people in
the Azores might disagree that it was a quiet week after a M5.4
and a pair of M4 events shook their islands (#3/5).  Other
moderate earthquakes of note include a M5.2 south of Panama
(#1/5), a M5.1 in Afghanistan, and a M5.2 along the Peru-Ecuador
Border (#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.
