This paper reviews issues, models, and methodologies arising out of the problems of predicting earthquakes and
forecasting earthquake risk. The emphasis is on statistical methods which attempt to quantify the probability of an
earthquake occurring within specified time, space, and magnitude windows. One recurring theme is that such
probabilities are best developed from models which specify a time-varying conditional intensity (conditional
probability per unit time, area or volume, and magnitude interval) for every point in the region under study. The
paper comprises three introductory sections, and three substantive sections. The former outline the current state of
earthquake prediction, earthquakes and their parameters, and the point process background. The latter cover the
estimation of background risk, the estimation of time-varying risk, and some specific examples of models and
prediction algorithms. The paper concludes with some brief comments on the links between forecasting
earthquakes and other forecasting problems.
