Etho-Geological Forecasting: Unusual Animal Behavior & Earthquake Prediction

I began researching the strange and mysterious behaviors of animals that are often reported prior to earthquakes in 1996 as part of a collaboration with British biologist Rupert Sheldrake. The initial research that I did became the backbone for the section on this subject in Dr. Sheldrake's bestselling book on the unexplained powers of animals, Dogs That Know When Their Owners are Coming Home. (This information was updated, with a summary of the earthquake data that has accumulated since Dogs That Know was published, in Dr. Sheldrake's more recent book The Sense of Being Stared At.) Since I compiled more material than Dr. Sheldrake could fit into the section in his book on this subject, I summarized much of this material in an earlier version of this essay, portions of which have been widely reprinted in books, magazines, and numerous web sites on the Internet.
