1992 Big Bear Earthquake
The 1992 Big Bear earthquake occurred at on June 28 in Big Bear Lake, California, with a Moment magnitude scale, 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 . Earthquake The Big Bear earthquake happened east of Los Angeles, and 3 hours 26 minutes after the M 7.3 1992 Landers earthquake occurred 22 miles (35 km) to the east. It was first believed to be an aftershock of the larger event. However, the United States Geological Survey determined that it was a separate, but related, shock. The two events are considered a regional sequence, rather than a main shock and aftershock. They were part of a complex pattern of regional stress adjustment that also led to the 1999 Hector Mine earthquake. Damage In the Big Bear area, severe damage was reported. Roughly 2,600 chimneys were destroyed, 20 homes were knocked off their foundations, and many unreinforced m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur ...

1992 In California
Year 199 ( CXCIX) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was sometimes known as year 952 '' Ab urbe condita''. The denomination 199 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Earthquakes In California
The earliest known California earthquake was documented in 1769 by the Spanish explorers and Catholic missionaries of the Portolá expedition as they traveled northward from San Diego along the Santa Ana River near the present site of Los Angeles. Ship captains and other explorers also documented earthquakes. As Spanish missions were constructed beginning in the late 18th century, earthquakes records were kept. After the missions were secularized in 1834, records were sparse until the California Gold Rush in the 1840s. From 1850–2004, there was about one potentially damaging event per year on average, though many of these did not cause serious consequences or loss of life. Since the three damaging earthquakes that occurred in the American Midwest and the East Coast ( 1755 Cape Ann, 1811–12 New Madrid, 1886 Charleston) were well known, it became apparent to settlers that the earthquake hazard was different in California. While the 1812 San Juan Capistrano, 1857 Fort Tejo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Seismological Centre
The International Seismological Centre (ISC) is a non-governmental, nonprofit organisation charged with the final collection, definitive analysis and publication of global seismicity. The ISC was formed in 1964 as an international organisation independent of national governments that would carry on the work of the International Seismological Summary in collecting and analyzing seismic data from around the world, and particularly to handle increased flow of data from the World-Wide Standard Seismograph Network (WWSSN), also established that year. The ISC considers its prime task to be the collection and re-analysis of all available earthquake seismic date in order to produce definitive data on earthquakes. The ISC's catalog is considered "the most complete and authoritative final depository of global earthquake parameter data." Purpose The main scientific goal of the Centre is the definitive compilation of earthquake information and the readings on which they are based. Collect ...

Southern California Earthquake Center
The Southern California Earthquake Center (SCEC) is a collaboration of more than 1,000 scientists across 100 research institutions with a mission to: conduct research on earthquakes in Southern California and elsewhere by gathering data, conducting theoretical studies, and performing computer simulations; integrate information into a comprehensive, physics-based understanding of earthquake phenomena; and communicate that understanding to end-users and society at large as useful knowledge for reducing earthquake risk and improving community resilience.. SCEC headquarters are at the University of Southern California. SCEC partners with many other research and education/outreach organizations in many disciplines. Primary funding for SCEC activities is provided by the National Science Foundation and the United States Geological Survey. The current director of SCEC is Yehuda Ben-Zion.

Inland Empire
The Inland Empire (IE) is a metropolitan area and region inland of and adjacent to coastal Southern California, centering around the cities of San Bernardino and Riverside, and bordering Los Angeles County to the west. It includes the cities of western Riverside County and southwestern San Bernardino County, and is considered to include the desert communities of the Coachella and Victor Valleys, respectively on the other sides of the San Gorgonio Pass and San Bernardino Mountains from the Santa Ana River watershed that forms the bulk of the Inland Empire; a much broader definition includes all of Riverside and San Bernardino counties. The combined land area of the counties of the Inland Empire is larger than ten U.S. states—West Virginia, Maryland, Hawaii, Massachusetts, Vermont, New Hampshire, New Jersey, Connecticut, Delaware and Rhode Island—and slightly smaller than the combined area of the five smallest U.S. states (New Hampshire through Rhode Island). ...
