Difference Between Tremors and Earthquakes
Tremors and earthquakes are seismic events, but they are different in what causes them, how strong they are, and what they do to the surface of the Earth. Tremors are continuous, low-intensity vibrations in the ground caused by both natural and man-made events. They can be caused by the movement of fluids in the Earth’s crust, volcanic activity, or heavy machinery and traffic. Most tremors don’t cause much damage; if they are small, people might not even notice them. They may, however, be a sign that a volcano is about to erupt or that changes are happening below the surface.
