Aardbeving veranderde draaiing van de aarde en verplaatste eilanden
Slashdot heeft
een post over het effect van de recente tsunami in Zuidoost-Aziƫ en de zeebeving en hoe dit de draaiing van de aarde heeft aangetast en hoe het eilanden heeft verplaatst:
"This week's deadly Asian Quake and Tsunami may have been so powerful, that it changed the rate of Earth's rotation. In a Reuters article, a NASA geophysicist theorizes that the quake compacted the Earth enough to speed up the planet's rotation by 3 microseconds. A second article says the quake moved undersea tectonic plates by up to 98 feet, shifting islands near Sumatra out to sea an unknown distance. Also, a USGS team wants images from commercial satellite operators to help pinpoint coastline damage. Lastly, an interesting article from the Australian Spaceguard Survey about the need for a Tsunami warning system in the Indian Ocean. The author comments that tsunami warnings may not help much, as people often flock to the coastline to see the giant waves."
