Earthquake and Frogs

You've probably heard plenty about the earthquake, but here's one follow up. Our guide worried aloud to us that the government should have predicted the earthquakes better. We told her that it is impossible to reliably predict earthquakes and the only thing you could do is prepare. That led into a discussion about 72-hour kits that we have and she thought the kits were an excellent idea (she phoned her mother to be prepared). Anyway, apparently there is some earthquake prediction by watching animals, as stated here: http://observers.france24.com/en/content/20080513-toads-predict-earthquake-dead-china . There were thousands of frogs moving in an area near the earthquake in the days before it happened.
