Why did so many animals escape December's Tsunami?

by Rupert Sheldrake

ABSTRACT:
Many animals escaped the great Asian tsunami on Boxing Day, 2004. Elephants in Sri Lanka and Sumatra moved to high ground before the giant waves struck; they did they same in Thailand, trumpeting before they did so. How did they know? The usual speculation is that the animals picked up tremors caused by the under-sea earthquake. This explanation seems to me unconvincing.
