Can horses detect natural disasters?

There are lots of stories about horses predicting natural disasters. In fact, horses do have a good weather sense - I've had horses warn me about an incoming storm before. They are also aware of earthquakes well before we are.

They aren't psychic - they just have better hearing and can hear distant thunder, rain, or the rumble of a quake before we can. Horses may get very antsy during a storm - wild horses would try to move out of its path as much as possible and domestic ones don't always seem to quite grasp that the barn has a roof on it!
