They are some of the most destructive and unpredictable forces on the planet.
But it seems some of the world’s largest earthquakes may be following a pattern after all – they seem to occur at times around the full or new moon.
This is when the gravitational pull from the moon and the sun on the Earth are at their greatest and it could be triggering fault lines into slipping, according to new research.
In the study, published in the Proceedings of the National Academy of Sciences, geologists at the University of Tokyo in Japan investigated roughly 81,000 low-frequency earthquakes from 2008 to 2015 along the Parkfield section of the San Andreas Fault.
The geologists have also discovered that some of the largest earthquakes in recent history appear to have occurred at times when tidal stress is highest reports Dailymail.
