Moonquakes are much less common and weaker than earthquakes, although they can last for up to an hour—a significantly longer time than terrestrial earthquakes—because of the absence of water to damp out the seismic vibrations.

Outside of devastating earthquakes, California experiences minor earthquakes on a regular basis.

Secondly, studying strong ground motions generated by earthquakes to assess the expected shaking from future earthquakes with similar characteristics.
