They occur from a matter of minutes to days or even longer before the main shock; for example, the 2002 Sumatra earthquake is regarded as a foreshock of the 2004 Indian Ocean earthquake with a delay of more than two years between the two events.
An earthquake cannot be identified as a foreshock until after a larger earthquake in the same area occurs.
Unfortunately, foreshocks are just like any other small earthquake. In California, that probability is about 6%. Intensity is based on the observed effects of ground shaking on people, buildings, and natural features. Fundamental questions of earthquake statistics, source behavior, and the estimation of earthquake probabilities from possible foreshocks; 2012; Article; Journal; Bulletin of the Seismological Society of America; Michael, Andrew J. ch 16 vocab. The frequency of events will diminish with time, but damaging earthquakes will remain a threat.A minor aftershock struck the Seattle area early Thursday morning, March 1, 2001. Copyright © 2010 by A foreshock is a smaller earthquake preceding a much larger earthquake. Does your subconscious link them to glamour and derring-do…or pleasure…or even terror?

U.S. Geological Survey FAQs: "Worldwide the probability that an earthquake will be followed within 3 days by a large earthquake nearby is somewhere just over 6%.

Your question touches on a technical matter of definition that the popular press and news often overstate inaccurately. Many scientists hope to use foreshocks to predict upcoming earthquakes. ‘Eat Out to Help Out’, the UK government instructs – healthily or otherwise, according to taste.
