Earth's Gravity Has Changed

This does not sound good.

COLUMBUS, Ohio -- U.S. scientists say they've determined Earth's gravity changed as a result of the giant 2004 Sumatran earthquake.

The discovery marked the first time scientists have used satellite data to detect changes in the Earth's surface caused by a massive earthquake.

The 9.1-magnitude December 2004 Sumatra-Andaman earthquake in the Indian Ocean produced a tsunami that killed approximately 230,000 people, while displacing more than 1 million others.

The event followed the slipping of two continental plates under the seafloor that raised ocean bed in the region by several feet for thousands of square miles.
