- 1Slow Earthquakes May Be Triggered by Sun and Moon Tides●Slow Earthquakes Sometimes Come Before Big Ones. The Sun and Moon May Be Setting Them Off Tidal stresses are comparable
New research suggests slow earthquakes — gradual fault movements that can precede major quakes — may be set off by tidal stresses from the Sun and Moon. The forces are described as comparable to a slight push from a hand, but when timed with a fault already near failure, they can be enough to get it moving. The findings could improve understanding of when slow slip events might escalate into destructive earthquakes.
