what unseen or unheard or unfelt by humans{at least nobody i've ever met} do many animals ,cats and dogs particualuy, react to the coming of earthquakes before they actually happen.

as i can remember there are only a few study in that topic but not yet proven in a large scale.
but 1 thing i know is that snakes feel it first. How?
Because they live underground.
you see earthquake is a seismic activity beneath the surface. they travel in waves. and when i say they travel.
because snake lives underground they feel the waves first even if the waves are weak. but if the waves gets stronger and stronger they leave their homes.
a good example of these is water in a tub. like a bath tub if you cause a seismic activity or knock or hit at one end of the tub, there are ripples that represents these waves. if you hit the tub harder you will produce a bigger ripples.
just like in quakes, weak waves are first detected then higher and higher.
hope you got what i meant.

Several precursors can be identified immediately before an earthquake. It is likely animals are more alert/sensitive to these clues and so pick up on them.
Precursors include:
1. Radon emmissions - the earth moves a little before a major earthquake which opens up dilational fractures in the ground ( some cases), releasing stored up radon.
2. Electromagnetic storms - you can get weird changes in electric charge locally before an earthquake as the conductivity of the ground changes (due to opening dilational fractures, fluid flow and friction I suspect). This would be a bit like the hairs on your neck standing up before a lightning strike. Humans can probably feel this too.
3. Small shifts in the ground - small foreshocks may be felt more easily by animals, warning of an impending earthquake.
Most animals are wild, or were wild more recently than humans, so have a more ahighly attuned 'nose' for danger, helping them to get out of the way when something bad happens!

Our senses of hearing and smell are not as capable as some animals. Gases released from fissures, the sub-sonic sound of bedrock "crunching" as it begins to edge its way towards the slip that causes a quake, the vibrations caused by this edging are some of the things dogs & cats especially can detect that humans cannot.

No one knows the answer to this questions. There are a few theories, like that animals can feel the earth move before we can, or that they are sensitive to electrical changes in the air or gas released from the earth. These are all theories. The answer is a mystery.

They seem to be able to detect changes in air pressure and also possibly hear the earthquake before it hits. One of my dogs is the best predictor of thunder storms. She shakes all over starting about an hour before a storm even starts. Maybe they're more tuned into nature and we ignorant humans need all our machinery to try to detect what they already know.

the ears act like antennaes so the beasties hear it on the radio, why do they hate the country stations?

maybe they might have a 6th sense of sorts
