Is Greenland Bouncing Back?
Yesterday there was a 6.6 earthquake off the coast of Greenland. It was widely reported in the Danish news, Greenland being part of the Kingdom of Denmark, and although it was quite deep and happened under the sea, it was still quite a big one by Greenlandic standards.
Although post glacial rebound hasn't really become a household term yet, I can't help wondering whether the astonishing levels of ice melt we are seeing this summer is somehow related. It's a pretty simple theory, as ice melts, the huge crushing force it exerted on the land mass is eased, allowing it to 'rebound' either upwards or laterally.
I'm no geologist, but I'm sure yesterday's tremor will not have gone unnoticed.
