earthquake produces which kind of sound before the main shock waves begins​

Answer 1

Answer:

The infrasonic waves are produced by large vibrating bodies. These waves are not audible to a human ear. For example, infrasonic waves are produced by the vibration of the earth’s surface during the earthquake. Some animals like elephants, rhinoceroses and whales etc. also produce infrasonic waves. Dog and cats have acted very strange before earthquakes, some believe that thy are hearing these sounds.
