Far in the woods, hours before a volcano eruption the animals in the area have all cleared out. Before an earthquake pet animals such as dogs and cats start acting strange. A mere coindence or do animals have the ability to predict or sense upcoming disasters?
"Along the shore of Indonesia's devastated Aceh province, the tsunami's impact on wildlife was limited."-washingtonpost.com. The article also states that elephants in Khao Lak before a 9,0 earthquake seemed agitated and uneasy, while flamingos in India left to safer forests before a tsunami hit.
In 2014 at the Yellowstone national park hikers observed buffalos running away from the mountain. This caused a scare because the mountain is in fact a supervolcano causing 3 supereruptions and mass extinctions 2 million years ago.
These occurances are fully anectdotal as it is difficult to experiment in the labratory with animals that can react to just about anything and not specifically relating to seismic activity; e.g. predators, feeling threatened. It is well known however that animals have a sixth sense. Or at least, better senses than ours. Sharks can detect electricity coming from their prey. Bats and dolphins use echolocation for communication (bats for hunting) which is sending out waves and detecting where the waves reflected back from.
A dogs' sense of smell is 10,000 to 100,000 times better than ours thus possibly detecting the chemical changes in the air before a disaster. For earthquakes, animals are thought to be able to sense the p waves (compression) before the large s wave comes.
Researchers in Japan where earthquakes commonly hit are studying animals hoping to detect something prior to an earthquake. But for now accurate earthquake prediction is almost impossible.
