Sumatra quake longest ever recorded: The true extent of the magnitude of the earthquake that caused the tsunami comes to light.
"Dramatic new data from the December 26, 2004, Sumatran-Andaman earthquake that generated deadly tsunamis show the event created the longest fault rupture and the longest duration of faulting ever observed." "Normally, a small earthquake might last less than a second; a moderate sized earthquake might last a few seconds. This earthquake lasted between 500 and 600 seconds." The quake released an amount of energy equal to a 100 gigaton bomb, and that power lasted longer than any quake ever recorded. The quake, centered in the Indian Ocean, also created the biggest gash in the Earth's seabed ever observed, nearly 800 miles. No place on Earth escaped movement. "Globally, this earthquake was large enough to basically vibrate the whole planet as much as half an inch, or a centimeter. Everywhere we had instruments, we could see motions." -K posted by Kaushik at 2:34 AM Comment (0)
