South Pacific Tsunami by Two Earthquakes

Originally, scientists believed, an earthquake triggered the deadly tsunami that hit Samoa, American Samoa, Tonga and in September 2009. However, one studies published tomorrow in the journal Nature argue that in lieu of one, actually there were one earthquakes which occurred in fast succession.

 John Beaven, lead author of a study, the researchers told Nature News if the island of Tonga, from two inches to the west after the earthquake, but GPS has proven that he moved about a foot East. They also provided the sea bottom, but has increased, indicating a different kind of "subduction" earthquake. An independent study by Thorne Lay confirmed the signs of other seismic earthquake.
