Toads could be used to forecast earthquakes days before they happen

Aside from ionosphere disturbances, nature has a number of ways that signify an earthquake's arrival far earlier than an iPhone can. Animals, for instance, are known to leave their homes and head to safety anywhere from a few seconds to weeks before humans can feel quakes. It was easy enough for researchers to determine the science behind the behavior seconds before ground tremors are felt, but the explanation behind instances of animal exodus days or weeks prior to any seismic activity has eluded them — until now, that is. Rachel Grant from the U.K. Open University and Friedemann Freund from NASA believe they may have figured it all out, thanks to a colony of toads. Read more...
