Earthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated limits, [1] [a] and particularly "the determination of parameters for the next strong earthquake to occur in a region". [2]
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.

Although many scientists still view earthquake predictions as challenging or impossible, [22] earthquake-cycle theories and modeling have long been consulted to produce hazard forecast values. For example, empirical models have been applied to forecast the likelihood of large earthquakes hitting the San Francisco Bay area in the near future. [23]
That earthquake changed Northern California forever — causing heavy damage to downtown Santa Cruz, parts of San Francisco, and causing the collapse of sections of Interstate 880 in Oakland and ...
Earthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated limits. [75] Many methods have been developed for predicting the time and place in which earthquakes will occur.
A view of Pacific Coastline in Pacifica, California, United States on December 5, 2024 as tsunami warning issued after 7.0 magnitude earthquake reported off Northern California coast.
During the same time frame, the technique also missed major earthquakes, in the sense that [32] "for earthquakes with Mb≥5.0, the ratio of the predicted to the total number of earthquakes is 6/12 (50%) and the success rate of the prediction is also 6/12 (50%) with the probability gain of a factor of 4. With a confidence level of 99.8%, the ...
