Amazing
This from a NYT article:
New studies of the giant earthquake that produced devastating tsunamis in the Indian Ocean show that its shock waves ricocheted around the globe for hours and lifted the earth's surface nearly an inch even half a world away.
The closest readings came from the Australian Cocos Islands, south of Sumatra, and Sri Lanka, and the farthest from Ecuador. The seismic data show the waves traveling around the earth for six hours.
Dr. Aster said that even in Ecuador, the shock wave displaced the earth's surface more than two centimeters, or nearly an inch, but the movement was too slow to be perceptible to humans. The jolt was much sharper in Pallekele, Sri Lanka, and shook the ground over a range of nearly four inches, he said.
