Astropedia 5.6: Why are earthquakes more likely to occur near a new Moon or a full Moon? During new or full moons, the gravitational pull the moon has on the earth causes the tides to be stronger. Thus, gravitational pull is what may increase the change of earthquakes, the gravitational pull also affects the tectonic plates, which can possibly cause them to move and cause an earthquake.
