. Seismicity Report for Northern California, the Nation, and the World for the week of October 27 - November 2, 1994 Data and text prepared by Steve Walter and Barry Hirshorn U.S. Geological Survey 345 Middlefield Rd. MS-977, Menlo Park, CA 94025 Graphics by Quentin Lindh 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).
