Why did the Earth vibrate for 9 days?
A mega-tsunami caused by a landslide in Greenland caused the Earth to vibrate for nine days, a new study has shown. The collapse of a 1.2km-high (0.7 miles) mountain peak last September caused water in the fjord below to splash back and forth, causing vibrations right through to the Earth's crust, researchers found.
