Gravitational Forces from Sun and Moon Can Cause Earthquakes

TIDAL forces parallel to a segment of the San Andreas Fault in central California may be causing non-volcanic tremors that could help predict earthquakes, researchers said.

Low-level tremors have long been associated with volcanoes, because they often warned of impending eruptions.

A study published in the journal Nature said these tremors beneath the San Andreas Fault could provide similar clues about earthquakes.

The researchers say the faint tug of the sun and the moon on the fault causes tremors well below the level where earthquakes occur.

The finding suggests that rock far underground is lubricated with pressurised water, allowing the rock to slip easily and weakening the fault.
