Seismicity Report for Northern California, the Nation, and the World for the week of July 14 - July 20, 1994 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 San Francisco Bay Area Activity was light during the past week. For the seven-day period ending at midnight on Wednesday, July 20, 1994 the U.S. Geological Survey office in Menlo Park recorded 17 earthquakes of magnitude one (M1) and greater within the San Francisco Bay area shown in Figure 1. Of these, only one exceeded M2 in size. This compares with 21 events last week, three of which were of M2 or larger. The largest event of the week was a M2.2 event on the 15th near Danville, just east of the Calaveras fault. There were two small events on the Hayward fault -- also on the 15th -- plus a pair of small events beneath the Pacific Ocean, offshore from Davenport, west of Santa Cruz. Northern & Central California Elsewhere in Northern California the largest event was a M3.3 off Cape Mendocino on the 16th; this event was accompanied by a small swarm of M2's. A sprinkling of M2's occurred along the Rodgers Creek - Maacama fault system during the week. Farther south, a pair of 2's occurred along the Green Valley fault SE of Napa on the 18th and 19th. South of the Bay area along the San Andreas there was a M3.1 in the Bitterwater Valley on the 15th. East of the Sierra's, there were two located events; a M2.2 near Bridgeport on the 18th, and a M2.7 near Markleeville on the 19th. Long Valley Caldera The only event of note was a M2.9 south of the Caldera on the 17th. Table 1.

domestic earthquakes during the past week occurred in southern California -- a M3.4 Northridge aftershock on the 17th -- and off the coast of Oregon, where there was a M4.5 event along the Blanco Fracture Zone -- about 200 km west of Coos Bay -- on the 13th. Elsewhere in North America, there was a magnitude 4.4 event in the mouth of the Gulf of California, east of La Paz on the 14th. And a M3.7 in New Brunswick on the 14th may have just been felt in Northern Maine. The Planet Earth (July 12-20) Elsewhere on the planet this last week, things were relatively peaceful, seismically speaking. The largest events were M5's in the Aleutians, and along the Indonesian Arc. Table 2.

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.
