Seismology

Smaller quakes that precede a main shock

A foreshock is a smaller earthquake that precedes a larger main shock on or near the same fault, recognisable as a foreshock usually only in hindsight once the larger event has occurred. Jones and Molnar's 1979 Some characteristics of foreshocks and their possible relationship to earthquake prediction and premonitory slip on faults documented how often main shocks are preceded by such activity and linked it to possible premonitory slip. The referent is precursory seismicity before a main shock, studied for whether it carries any forecasting value, and measured by the rate and pattern of events in the lead-up.[1]

Unit
The rate and timing of smaller events preceding a main shock
Recovery means
Not applicable
Measured by
Identified retrospectively from catalogues as elevated seismicity before a main shock, quantified by foreshock occurrence rates and inter-event times
