Giant quake coming? Feel for Earth tides

摘要

Massive earthquakes, such as the one that triggered the Indian Ocean tsunami on 26 December 2004, could be predicted years in advance by monitoring tremors caused by "Earth tides".rnThe gravitational pull of the sun and moon deforms the Earth's crust and upper mantle, creating bulges and dips in the planet called Earth tides. These can reduce the pressure on tectonic plates,rncausing them to slip past each other, inducing tremors.
