Seismicity Report for Northern California,
the Nation, and the World for the week of
October 27 - November 2, 1994

San Francisco Bay Area
It was a fairly quiet week in the Bay Area with only two earthquakes as
large as M2. For the seven-day period ending at midnight on Wednesday,
November 2, 1994 the U.S. Geological Survey office in Menlo Park recorded
28 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 previous seven-day period (October 20 - 26), seven of which were as
large as M2.
Both M2 earthquakes occurred in the East Bay northeast of San Jose.
The first occurred just before noon last Friday morning about three miles
southeast of Fremont (#2 in figure 1). The following day a M2.5 occurred
in the northern Diablo Range about 15 miles southeast of Livermore (#3/1).
Neither earthquake was reported to have been felt.
The only other seismicity of note was a small cluster of five M1
earthquakes on the central Hayward fault beneath the foothills of eastern
San Leandro (#1/1). They occurred in essentially the same location as a
M2.8 on October 23.
Northern & Central California
Seismicity throughout northern and central California was down from
that seen in recent weeks. Except for the still active aftershock
sequence east of Markleeville there were no earthquakes as large as M3 in
the region. Cape Mendocino was exceptionally quiet with only four
earthquakes as large as M2, all located offshore of the Cape along the
Mendocino fracture zone (#3,#4/2). Similarly, the Coast Range experienced
only a few M2 earthquakes during the week including a M2.1 on the central
Maacama fault just northeast of Willits (#1/2) and a pair of M2's at the
Geysers geothermal area. Central California experienced nothing larger
than one M2.0 in the Coalinga area, about 20 miles east of Avenal.
Activity in the eastern Sierra Nevada was limited to a pair of M2's in the
eastern Mono Lake basin (#5/2) and the continuing activity east of
Markleeville, aftershocks to a M6.0 earthquake in early September (#2/2).
Long Valley Caldera
There were no earthquakes as large as M2 within the caldera during the
week. Activity south of the caldera included a M2.0 event just west of
Convict Lake (#1/3), a pair of M2's southeast of Mt. Morrison (#2/3) and a
pair of M2's east of the Round Valley fault and about ten miles northwest
of Bishop (#3/3).
USA Seismicity (October 25 - November 1)
One of the larger earthquakes on the planet occurred offshore of Oregon
last Thursday, according to information provided by the National
Earthquake Information Center (#1/4). The earthquake occurred along the
Blanco Fracture Zone about 150 miles west of Coos Bay, OR.
A pair of small earthquakes occurred in the southern Hells Canyon
region of the Snake River along the Oregon/Idaho border (#2/4). The
earthquakes were felt at Brownlee and Oxbow, Oregon.
Nevada also experienced several small events including a pair of M3's
south of Eureka (#4/4) and a M3.6 beneath the upper reaches of the Lake
Meade reservoir (#5/4).
Southern California experienced only one earthquake as large as M3
(#6/4). This M3.2 earthquake occurred Sunday afternoon about 17 miles
north of Yucca Valley and was yet another aftershock to the M7.5 Landers
earthquake that occurred in June, 1992.
The Planet Earth (October 25 - November 1)
One of the more unusual earthquakes to occur on the planet was a Mb5.5
in the central Republic of South Africa, about 130 miles northeast of
Kimberley (#4/5). It occurred well within the stable part of the African
plate, far removed from the plate boundaries that generate most
earthquakes.
More typical were several moderate to large earthquakes that occurred
along convergent plate boundaries: continued M4-5 aftershocks in the
southern Kurils where the Pacific Plate slips beneath the Asian landmass
(#1/5); a Mb5.6 in the Taiwan region where the Philippines plate collides
with Southeast Asia (#3/5); a Ms6.3 in northern Sumatera where the Indo-
Australian plate also underthrusts Southeast Asia (#5/5); a Mb 5.1 nearly
600 km beneath Argentina reflecting the depth that the Pacific plate has
underthrust South America (#2/5); and a Mb5.4 beneath Costa Rica, where
the relatively small Cocos plate has been subducted beneath Central
America (#6/5).
