In a study published in the journal Seismological Research Letters, Hough looked at data from 204 earthquakes measuring 8 on the Richter scale or more from the 1600s.
As a result, he found no evidence to suggest that earthquake levels are significantly affected by the Earth's position on the sun or the moon.
However, Hough said that does not mean there is no pattern related to the position of the moon and earthquake.
He did find that the highest number of earthquakes occurred on a certain day, ie 7 days after the full moon.
"There are some good studies that show that the tidal strength of the seawater slightly triggers the quake," Hough said.
