Definition

An earthquake is a sudden movement within the Earth’s crust or the upper mantle that releases tectonic stress and, usually, originates seismic waves. The hierarchy of movable lithospheric volumes composes a large nonlinear dynamical system. Prediction of such a system in a sense of extrapolation of trajectory into the future is futile. However, upon coarse-graining the integral empirical regularities emerge opening possibilities of earthquake prediction (Keilis-Borok et al., 2001).

Earthquake predictionis a statement about future earthquake occurrence based on the information, data, and scientific methods that are available now. To predict an earthquake, someone “must specify the expected magnitude range, the geographical area within which it will occur, and the time interval within which it will happen with sufficient precision so that the ultimate success or failure of the prediction can readily be judged. Only by careful recording and analysis of failures as well as...
