Chickens and even pigs were too nervous to eat, and dogs refused to go inside buildings. Mice ran out of the fields looking for places to hide, and fish jumped out of the water.

I think they were warning signs.Senses of some of the animals are very sharp,which can feel the coming of the natural disaster.What’s more, the movement inside the earth may cause some changes of the objects on its surface.
