Seismicity Report for Northern California, the Nation, and the World for the week of June 16 - 22, 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 Seismicity remained at a low level for yet another week. For the seven-day period ending at midnight on Wednesday, June 22, 1994 the U.S. Geological Survey office in Menlo Park recorded just 15 earthquakes of magnitude one (Mm) and greater within the San Francisco Bay area shown in Figure 1. None were as large as M2. This total compares to 20 earthquakes during the previous seven-day period (June 9 - 15), two of which were as large as M2. The largest earthquake in the Bay Area during the week was a M1.9, notable only because it occurred along the San Gregorio fault just northeast of the small town of San Gregorio (#1 in figure 1). Two other small events worth mentioning were a pair of M1's on the central Hayward fault about three miles northeast of central San Leandro (#2/1). The largest recent earthquake in this vicinity was a M3.6 in late December, 1992. Northern & Central California Activity was up a bit in northern California during the past week. Not surprisingly much of the activity occurred in the Cape Mendocino area. The first notable earthquake in the area was a M2.9 last Thursday just off the coast about 20 miles southwest of Eureka (#1/2). Then early Sunday morning a M4.7 occurred along the Mendocino fracture zone just nine miles west of Petrolia (#3/2). The earthquake was felt from Garbervile, about 80 miles south of Eureka, to McKinleyville, about ten miles north of Eureka. The earthquake was followed by a number of aftershocks, the largest a M3.1 that occurred about two hours after the mainshock. In addition, a M3.4 occurred farther out along the Mendocino transform early the next morning (#4/2). Sunday's M4.7 event was the largest earthquake to occur in this area since a M6.9 occurred near Petrolia on April 26, 1992. Three other felt earthquakes occurred in northern California during the week. Coincidentally, the first of these occurred just one hour before the Mendocino earthquake, discussed above. This M3.4 earthquake was located about eight miles southwest of Chester in the northernmost Sierra Nevada (#2/2). Then on Tuesday two M3 earthquakes occurred. The first, a M3.1 at the Geysers geothermal area, occurred just after midnight (#5/2). The second occurred later that evening about nine miles southeast of Carson City, Nevada (#6/2). Central California was quiet with only a few small M2's along the creeping segment of the San Andreas and a M2.2 east of Coalinga. The only notable earthquake in the area was a M2.6 beneath the central Sierra Nevada about 25 miles east of Merced (#7/2). Long Valley Caldera For the 9th straight week there were no earthquakes within the Long Valley caldera that were as large as M2. South of the caldera a M2.7 occurred about two miles west of Convict Lake (#1/3) and a pair of M2's occurred just north of Mt. Morrison (#2,#3/3). USA Seismicity (June 12 - 22) According to data provided by the National Earthquake Information Center, a number of states experienced felt earthquakes in the past ten days. Largest of these was a M5.0 last Thursday in southern California that was felt as far away as Pasadena (#3/4). This was an aftershock to the M7.3 Landers earthquake of June 28, 1992. Smaller, but still large enough to be felt, were a pair of events in western Washington. The first of these was M4.0 last Friday that was located near the southern end of Puget Sound (#2/4). It was followed just after midnight on Sunday by a M4.2 in the central Cascade Mountains that was felt in the Skykomish area (#6/4). Other events in the lower 48 states included several M3 aftershocks in eastern Idaho (#4/4), a M2.7 in northwestern Montana (#5/4), and a M4.3 offshore of southern Oregon (#1/4). The Planet Earth (June 12 - 22) A moderately strong Mb6.0 earthquake shook southern Iran Monday, killing two people and injuring 50 (#5/5). A landslide triggered by the earthquakes blocked a tunnel in the Zagros Mountains. The largest earthquake on the planet occurred on South Island, New Zealand (#4/5). The Ms7.1 earthquake produced some structural damage in Christchurch and triggered landslides that blocked the highway between Arthur's Pass and Christchurch. Large enough to be classified as a major earthquake, it was felt throughout South Island and in the southern parts of North Island. Other earthquakes of note around the world include aftershocks to the M7.2 Java quake earlier this month (#1/5), a Mb5.0 near the coast of central Chile that was felt as far away as Santiago (#2/5), and a Mb5.6 in souther Peru (#3/5).

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.
