In a little-heeded warning issued at a 2009 conference on the subject, experts outlined a range of mechanisms by which climate change could already be causing more earthquakes, tsunamis, and volcanic activity. "When the ice is lost, the earth's crust bounces back up again and that triggers earthquakes, which trigger submarine landslides, which cause tsunamis," Bill McGuire, professor at University College London, told Reuters.
Melting ice masses change the pressures on the underlying earth, which can lead to earthquakes and tsunamis, but that's just the beginning. Rising seas also change the balance of mass across earth's surface, putting new strain on old earthquake faults, and may have been partly to blame for the devastating 2004 tsunami that struck Southeast Asia, according to experts from the China Meteorological Administration.
