Earthquake prediction is an immature science – it has not yet led to a successful prediction of an earthquake from first physical principles. Research into methods of prediction therefore focus on empirical analysis, with two general approaches: either identifying distinctive precursors to earthquakes, or identifying some kind of geophysical ...
Kagan & Knopoff (1987, p. 1563) define prediction (in part) "to be a formal rule where by the available space-time-seismic moment manifold of earthquake occurrence is significantly contracted ...."</ref> [2] Both forecasting and prediction of earthquakes are distinguished from earthquake warning systems, which, upon detection of an earthquake ...
Berkland's predictions have been either self-published in his newsletter or website, or announced in various interviews or speaking engagements. [8] His notoriety arose from an interview published in the Gilroy Dispatch on October 13, 1989, where he predicted that an earthquake with a magnitude between 3.5 and 6.0 would occur in the San Francisco Bay Area between October 14 and October 21.

For U.S. earthquake scientists, Japan's 'megaquake' warning renewed worries about when and how to warn the public if they find clues that the 'big one' might be coming for the West COast.
Of particular concern are signals of massive earthquakes in the region’s geologic history. Many researchers have chased clues of the last “big one”: an 8.7-magnitude earthquake in 1700.
The seismic monitoring area at the University of Memphis’ Center for Earthquake Research and Information, can be seen during a tour on Thursday, May 02 2024 at 3890 Central Avenue in Memphis, Tenn.
Earthquakes in the New Madrid and Wabash Valley seismic zones from 1974 to 2002, with magnitudes larger than 2.5. The zone had four of the largest earthquakes in recorded North American history, with moment magnitudes estimated to be as large as 7 or greater, all occurring within a 3-month period between December 1811 and February 1812. Many of ...
The 7.4-magnitude earthquake that struck Taiwan on Wednesday can provide vital lessons for Southern California as it prepares for the next big temblor.
