Warming Greenland glacier causes earthquakes

News Update: Scientists have linked the fast-melting and calving Jakobshavn Glacier in Greenland with increased seismic activity that registers around the world. When a large chunk break off and spills into the fiord it scrapes along the sea bottom and causes quakes of 4.6 to 5.1. Want to see a video of the calving glacier? (note: it’s speeded up 25 times, since these things happen slowly) (Source: Discover)
