The day after Christmas in 2004, an undersea earthquake occurred in the Indian Ocean near the west coast of Sumatria, releasing the energy equivalent to 23,000 atom bombs like the one that hit Hiroshima and causing the deaths of 227,898 people in fifteen nations, according to the U.S. Geological Survey. It registered a magnitude of 9.1 and lasted close to ten minutes. It triggered a tsunami which reached heights of 50 feet and traveled as far away as Africa, 3,000 miles away. It also caused the earth to vibrate almost half an inch, triggering numerous other earthquakes, including one in Alaska. Perhaps the most mind-boggling fact is that the quake altered the rotation of the Earth, caused it to wobble on its axis an inch or more, and shortened the length of a day by 2.65 microseconds.
