Seismicity Report for Northern California, the Nation, and the World for the week of November 4 - 9, 1993 Data and text prepared by Steve Walter, Barry Hirshorn, and Allan Lindh U.S. Geological Survey 345 Middlefield Rd. MS-977, Menlo Park, CA 94025 Graphics by Quentin Lindh Note: Because Veteran's Day falls on Thursday, this report is being written a day early and covers only the 6-day period through Tuesday, November 9. Next week's report will cover an 8-day period to capture the "missing" day. The following week will see a 6-day report again in order to accommodate the Thanksgiving holiday. My apologies for any inconvenience these changes may cause you and your readers. San Francisco Bay Area For the 6-day period ending at midnight on Wednesday, November 9, 1993 the U.S. Geological Survey office in Menlo Park recorded just 11 earthquakes of magnitude one (M1) and greater within the San Francisco Bay area shown in Figure 1. Three of these were as large as M2.0. This total compares to 13 earthquakes during the previous week (October 28 - November 3), none of which were as large as M2. Most of the activity during the past six days occurred on the central Calaveras fault east and southeast of San Jose. The largest of these was a M2.7 last Saturday night that occurred about 10 miles east of San Jose (#2 in figure 1). A slightly smaller M2.3 occurred late Tuesday morning about eight miles north of Morgan Hill (#3/1). Activity on the San Andreas was limited to the southern part of the creeping segment where a M2.2 occurred 12 miles southeast of Hollister last Friday morning (#1/1). Figure 2 shows several additional M2's on the creeping segment just south of the Bay Area box. Northern & Central California Figure 2 also shows a small sequence just north of the Bay Area in the western hills of the Sonoma Valley (#8/2). This sequence occurred Monday afternoon about seven miles east-southeast of Santa Rosa and included a M3.5 earthquake that was felt widely in the epicentral area. Several M2 aftershocks followed over the course of the afternoon, the largest a M2.4 just before 5:00. As figure 2 suggests, this activity occurred east of the Rogers Creek fault, probably on one of the several small strands that run parallel to the Rogers Creek fault in the hills west of Glen Ellen. A M2.7 occurred in the same location as this sequence on November 3 (see last week's summary). Increased activity was observed in the North Coast area. Cape Mendocino, which experienced only one or two M2's during the previous two weeks, saw a half dozen earthquakes as large as M2.0, the largest a M3.2 last Friday afternoon (#2/2). Several of these events in the area of the Cape had focal depths greater than 20km, indicating they were related to the subducted Gorda Plate. Other subduction earthquakes occurred beneath the western Klamath mountains. The first and largest was a 36-km-deep M3.2 that occurred last Friday evening about 46 miles southeast of Crescent City (#4/2). On Saturday evening a 12-km-deep M2.8 occurred about 26 miles west-southwest of Crescent City. It was followed Monday morning by a 29-km-deep M2.2 event about 30 miles east of Eureka (#7/2). The only other events of note in northern California were a pair of M2's southeast of Lake Almanor last Thursday afternoon (#1/2). Central California remained quiet with nothing more than a trio of M2's along the central creeping San Andreas and a pair of M2's north of Coalinga (#6/2). The eastern margin of the Sierra Nevada experienced a few M2 events. First were a M2.9 and a M2.7 in the western Chalfant Valley last Friday afternoon (#3/2). They were followed by a M2.4 Monday beneath the northwest edge of Mono Lake Monday (#9/2) and by a M2.3 Tuesday evening beneath the central Owens Valley, about 31 miles south of Lone Pine (#10/2). Long Valley Caldera Activity in the caldera declined a bit from last week. The only M2 earthquakes occurred Monday afternoon in a small cluster beneath the southwest side of the resurgent dome, near the junction of highway 395 and Mammoth Lakes road (#3/3). The cluster included four M2 events, all occurring within about a two hour period. Some earthquakes were also observed along the southeast side of the resurgent dome but none were as large as M2.0. Activity south of the caldera declined with no earthquakes of any size in the Red Slate Mountain area, site of a M4.5 in early August. The largest event in the area was a M3.7 near the southwest end of Convict Lake last Friday afternoon (#2/3). It was preceded by a M2.3 foreshock. Other events of interest include a pair of M2's east of Mt. Morrison, the first last Thursday, the second Monday evening (#3/3). USA Seismicity (October 30 - November 10) According to data provided by the National Earthquake Information Center, there were only a couple of notable earthquakes in the lower 48 states outside of California. Small temblors continue in the Klamath Falls, OR area, aftershocks to a M6.0 event in late September (#2/4). Wednesday morning a light earthquakes occurred in western Idaho about 4 miles west-southwest of Challis and about 80 miles northeast of Boise (#3/4). There have been no reports of any damage from this small quake. The Planet Earth (October 30 - November 10) Only two recent earthquakes were large enough to be described as "strong" (M6.0 - M6.9). First there was a M6.0 beneath San Juan Province in western Argentina that was widely felt in the province (#1/5). Second, a Ms6.2 occurred beneath the Bismark Sea off the north coast of Papua New Guinea (#3/5). This is yet another aftershock to the pair of M7's that struck the area in October. Moderate earthquakes (M5.0 - M5.9) were much more common, especially around the western Pacific margin. Other notable earthquakes included a pair of mid-ocean earthquakes, the first a Mb5.4 south of Australia (#2/5), the second a Ms5.4 near the Chagos Islands in the central Indian Ocean (#4/5). Greece was shaken by a M4.9 that was felt at Patras and Aeghio (#5/5) and a Mb5.0 was reported by people throughout the island of Puerto Rico (#6/5). Table 1.

Notes: 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.
