This must have been zombie Thucydides:
In some animals, however, there seems to be a genuine ability to sense the changes that occur before earthquakes.Perhaps the first person to record this was the Greek historian Thucydides, in 373 B.C. Days before a massive earthquake hit the city of Helice, he says all manner of animals streamed out. Dogs, rats and weasels, they ran for the hills. Snakes sensed the coming catastrophe too, and they slithered for the highlands.
