TL;DR: The 2004 Parkfield earthquake, with its lack of obvious precursors, demonstrates that reliable short-term earthquake prediction still is not achievable and the next generation of models that can provide better predictions of the strength and location of damaging ground shaking should be developed.

TL;DR: The M_w 7.1 Hector Mine, California, earthquake occurred at 9:46 GMT on 16 October 1999 as mentioned in this paper, with an epicentral coordinates of 34.59°N 116.27°W and a hypocentral depth of 5 ± 3 km.

The 1987 Whittier Narrows Earthquake in the Los Angeles Metropolitan Area, California
Egill Hauksson,Lucile M. Jones,Thomas L. Davis,L. Katherine Hutton,Patrick Williams,Allison L. Bent,A. Gerald Brady,Paul A. Reasenberg,Andrew J. Michael,Robert F. Yerkes,Edwin Etheredge,Ronald L. Porcella,Malcolm J. S. Johnston,Glen Reagor,Carl W. Stover,Charles G. Bufe,Edward Cranswick,A. Shakal +17 more
TL;DR: The Whittier Narrows earthquake sequence (local magnitude, M_L = 5.9), which caused over $358 million damage, indicates that assessments of earthquake hazards in the Los Angeles metropolitan area may be underestimated as discussed by the authors.
Journal ArticleDOI
Major improvements in progress for Southern California Earthquake Monitoring
Jim Mori,Hiroo Kanamori,James L. Davis,Egill Hauksson,Robert W. Clayton,Thomas H. Heaton,Lucile M. Jones,A. Shakal,Ron Porcella +8 more
TL;DR: The TriNet project as discussed by the authors is a seismic and strong-motion monitoring network developed by the California Institute of Technology (Caltech), the U.S. Geological Survey (USGS), and the California Division of Mines and Geology (CDMG) of the state's Department of Conservation.

TL;DR: The most costly American earthquake since 1906 struck Los Angeles on 17 January 1994 as discussed by the authors, which resulted from more than 3 meters of reverse slip on a 1 5-kilometer-long south-dipping thrust fault that raised the Santa Susana mountains by as much as 70 centimeters.
