San Francisco Bay Area    

   Another quiet week in the Bay Area.  For the seven-day period ending at
midnight on Wednesday, October 5, 1994 the U.S. Geological Survey office
in Menlo Park recorded 15 earthquakes of magnitude one (M1) and greater
within the San Francisco Bay area shown in Figure 1.  Only one of these
was as large as M2.  This total compares to 19 earthquakes during the
previous seven-day period (September 22 - 28), three of which were as
large as M2.
   The lone M2 earthquake occurred Tuesday evening on the creeping segment
of the San Andreas about two miles west of San Juan Bautista (#1 in figure
1).  A similar sized quake occurred in this same location less than two
weeks ago.  The only other earthquakes on the San Andreas were three M1's
on the creeping segment southeast of San Juan Bautista and a M1.0 on the
southern Loma Prieta segment about three miles northeast of Watsonville.
   The Calaveras fault was equally quiet with four M1's along the central
and southern parts of the fault.  The only other activity of note were
three M1's on the northern Hayward fault, the largest a M1.7 in northeast
Oakland (#2/1).

Northern & Central California

   Aftershock activity continued in both the Cape Mendocino and
Markleeville areas.  The Mendocino fracture zone, site of a M7.0 on
September 1, saw a continued decline in activity with just ten aftershocks
as large as M2.0 (#5/2).  This is the second week in a row without an
aftershock as large as M3.  In contrast, activity in the Markleeville area
remained rather high with 37 aftershocks as large as M2.0, seven of which
were larger than M3.0 (#3/2).  The Markleeville area was the site of a
M6.0 earthquake on September 12.
   Other earthquakes of note in northern California include a M3.2 about
120 miles west of Crescent City (#8/2), a M2.0 subduction earthquake 31
kilometers beneath Eureka (#6/2), and a M3.0 about 20 miles northeast of
Red Bluff (#7/2).
   Central California experienced a couple M2 events in the Coalinga area,
the largest a M2.1 early last Thursday morning (#2/2).  The creeping
segment of the San Andreas was quite active at the M1 level; however only
one quake was as large as M2, a M2.4 early Wednesday afternoon.  Later
Wednesday evening a M2.7 occurred in the Coast Range mountains about
eleven miles north-northeast of San Simeon (#9/2).

Long Valley Caldera

   For the second week in a row a small cluster of earthquakes occurred
beneath the south side of the caldera near Mammoth Lakes.  This week's
activity all occurred Sunday night when four M2 earthquakes and numerous
smaller events were recorded (#2/3).  No reports were received that any of
the M2's were felt locally although the epicenters were only about two
miles southeast of the town.
   About half an hour after the caldera activity ended, a small cluster of
earthquakes occurred southeast of Mt. Morrison (#3/3).  This activity was
capped by a M3.0 event, the first M3 earthquake south of the caldera since
early June.

USA Seismicity (September 26 - October 5)

   According to information provided by the National Earthquake
Information Center there were only a couple of significant earthquakes in
the lower 48 states, outside of California, during the past week.  On
Sunday morning a M3.6 occurred in central Massachusetts near the tiny town
of Gilbertville (#1/4).  It was felt in Massachusetts from Boston to
Springfield and as far north as Merrimack, New Hampshire.  The following
morning, a M4.8 occurred just across Arizona's border with Sonora, Mexico
(#2/4).  This quake was felt in Yuma, Arizona and throughout much of
southern San Diego county, California.

The Planet Earth (September 26 - October 5)

   A major earthquake measuring 8.2 on the Richter scale occurred on
October 4 about 85 miles southeast of the island of Iturup in the southern
Kuril Islands or approximately 165 miles northeast of the town of Kushiro
in northern Hokkaido, Japan (#4/5).  The earthquake was strong enough to
shake buildings over 650 miles away in Tokyo.  At least 10 people were
reported killed, most on the southernmost Kuril Islands where shaking was
most severe.  Japan reported no deaths directly attributable to the
earthquake although damage in northern Hokkaido was extensive and at least
180 people were injured.  A tsunami wave generated by the earthquake was
reported to have washed over Zeleny (Green) Island in the southern
Kurils.  A general tsunami warning was issued for the northern and eastern
Pacific margins but was later cancelled after tsunami waves of less than
half a meter were measured at Wake Island and in the Hawaiian Islands.
   Other earthquakes of note during the week include a pair of M6's in the
Vanuatu Islands region (#3/5), a Ms5.3 south of Panama (#1/5) and a Ms5.3
in the Rat Islands of the Aleutian archipelago (#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.
