The destruction and disappearance of ancient cultures mark the history of human civilization, making for fascinating stories and cautionary tales. The longevity of today’s societies may depend upon separating fact from fiction, and archeologists and seismologists are figuring out how to join forces to do just that with respect to ancient earthquakes, as detailed in new studies presented at the international conference of the Seismological Society of America.

Archaeoseismology, a young scientific discipline that studies past earthquakes in the archaeological record, allows scientists to broaden the time window to detect these rare seismic catastrophic events. But archaeological evidence for past earthquakes raises a lot of reservations from seismologists, some of them strongly questioning whether man-made structures can be used as earthquake indicators at all.
