View Full Version : Earthquake Should Show a Gravity Scar

2005-Sep-07, 01:54 AM
SUMMARY: The devastating earthquake in Sumatra late last year was so powerful that it created a warp in the Earth's gravity field that should be visible by the ESA's Gravity Field and Ocean Circulation Explorer (GOCE) due to launch next year. During the earthquake, the sea floor along the fault line raised up 6 metres (20 feet), shifting the local gravity slightly. Similar shifts in gravity happen when large areas of ice melt, or volcanoes bulge up. By measuring these shifts, GOCE will help scientists understand the forces involved in earthquakes.
