Earthquakes: the highest stage of a earthquake can be devastating cracking open grounds and destroying everything in its path which also means that it can destroy certain species homes (trees, underground, mountains) which can kill them. Also they can cause land slides which can wipe out a species instantly if strong enough. Even the after affect can causes species to go extinct because if they can't find shelter or food then they could eventually die of starvation or dehydration.
