One common prob­ lem is the anchor-boltconnection between the concrete foundation and the wood sill plate. For example, the Ridgecrest sequence shares similar characteristics to the 1992 M w 6.2 Big Bear and M w 7.3 Landers earthquakes (Sieh et al., 1993; Jones and Hough, 1995) Ponti et al. 1992 Big Bear earthquake.

The Big Bear event is associated with its own fore- and Big Bear City, CA has a very high earthquake risk, with a total of 15,939 earthquakes since 1931. The June 28, 1992 Big Bear earthquake in southern California was assumed to have ruptured along a northeast‐trending plane, as suggested by long‐term aftershock distribution. From overall aftershock locations and long-period focal studies, rupture is generally assumed to have propagated northeast. The Landers sequence in southern California includes the Joshua Tree, Landers and Big Bear earthquakes with magnitudes of … However, the United States Geological Survey determined that this was a separate, but related, earthquake. The M• = 7.3 Landers earthquake of 11:58 GMT, June 28, 1992 was followed by tens of thousands of aftershocks, [Kanamori, et al., 1992].

If the Earth behaves in … The June 28, 1992 Big Bear earthquake in southern California was assumed to have ruptured along a northeast-trending plane, as suggested by long-term aftershock distribution. The focal mechanisms and aftershock distribution for this earthquake indicate left- lateral strike slip on a NE striking fault. (28 June 1992; 34.22 , 116.43 ), and M 6.2 Big Bear (28 June 1992; 34.21 , 1 16.83 ) earthquakes (stars) and their aftershocks (squares).

The rupture belt is a nearly perfectly circular segment, about 80-km long, that activated along an arc of 60 o with the radius centered near the San Andreas fault at San Bernardino, CA. The 1992 Big Bear earthquake occurred at 08:05:33 PDT on June 28 in Big Bear Lake, California, with a moment magnitude of 6.5 and a maximum perceived intensity of VIII (Severe) on the Mercalli intensity scale.The earthquake occurred at a relatively shallow depth of 5 kilometers (3.1 mi) and caused landslides in the San Bernardino Mountains.. 7, Issue 4 (November 1993) EARTHQUAKE DAMAGE LESSONS FROM BIG BEAR LAKE, CALIFORNIA, 19923 Discussion by Robert W.

Big Bear Alpine Zoo reopens with new, more spacious facility After two decades of planning, fundraising and construction, the Big Bear Alpine Zoo opened its doors to the public at its brand-new, state-of–the-art facility on Thursday, Nov. 5. Peak ground accelerations (PGA) at 181 sites for the Landers M W 7.3 earthquake and at 85 sites for the Big Bear M W 6.2 aftershock are compared to the Joyner and Boore (1988) (JB) attenuation relationships and examined for spatial variations. The 6.5 magnitude Big Bear earthquake, which hit about three hours after the Landers mainshock, was originally considered an aftershock. This report supersedes an earlier report (CSMIP, 1993) by including the processing of the reference ground-response station data from both earthquakes and the bridge data from the Big Bear earthquake. The USGS database shows that there is a 99.61% chance of a major earthquake within 50km of Big Bear City, CA within the next 50 years. The largest of these was the Big Bear earthquake that occurred three hours later and was associated with signifi- cant damage in Big Bear City. Together the Landers and Big Bear earthquakes raised the stress along the San Bernardino segment of the southern San Andreas fault by 2-6 bars, hastening the next great earthquake there by about a decade.

It was on Sunday, June 28, 1992 at 8:05am that the Big Bear Valley was rattled by a 6.4 magnitude earthquake, which the U.S. Geological Survey determined was an aftershock of the 7.3 magnitude Landers earthquake, which shook Inland Empire at 4:57am that same morning. The preliminary estimate of damage is $92.1 million for the Landers and the Big Bear Lake events. We analyze 1787 earthquakes of the 1992 to 1993 Big Bear aftershock sequence in southern California, which were recorded by both the Southern California Seismic Network (SCSN) and the Cajon Pass borehole seismometer at 2.5-km depth.
