Pretty interesting research coming out on the giant earthquake and tsunami that killed 176,000 people earlier this year. This is a fascinating description of what exactly happened:
At that spot the Eurasian plate was being pulled downward by the descending Indo-Australian plate. The quake released the edge of the Eurasian plate, which sprang up, lifting the ocean floor and sending the sea water off in the giant wave that killed so many, the researchers reported.
And how about this:
And the temblor “delivered a blow to our planet” that was felt for weeks, noted a team of researchers led by Jeffrey Park of Yale University. His group calculated that the quake caused the planet to oscillate like a bell, at periods of about 17 minutes, which they were able to measure for weeks afterward.
