An earthquake occurring as a consequence of a larger earthquake (referred to as the mainshock) at roughly the same location. Aftershocks are smaller than the mainshock and within 1-2 fault lengths distance from the mainshock fault. The sequence of such earthquakes following a larger one generally shows a regular decrease in the rate of occurrence, first discovered by Omori (1894), indicating a stress relaxation and redistribution process as the rocks accommodate to their new post-earthquake state. Aftershocks can continue over a period of weeks, months, or years, decreasing in frequency with time. In general, the larger the mainshock, the larger and more numerous the aftershocks, and the longer they will continue.
