June 28, 1996: Earthquake Prediction - Jim Berkland

Jim Berkland explains his method of earthquake prediction using tidal forces, animal behavior, groundwater changes, and clusters of smaller seismic events.

Art Bell asks how forecasts can be tested without overstating uncertain signals and revisits Berkland’s best-known predictions. Callers report local observations and question whether unconventional indicators can provide useful warnings beyond standard seismology.
