While hot springs are in few areas of Greenland. They are not common and not as hot as those in Iceland. I do not know a lot about the details of geology of Greenland. So I am unsure on the details why there are hot springs in Greenland to start with. But this news is even more interesting for that exact reason.
According to the Greeland Radio new hot springs opened up in the village of Kangersuatsiaq of the west coast of Greenland. After an what appears to be swarm of earthquakes, with the largest one somewhere around ML2.9 to ML3.? (enough to sake people pictures on the wall). A new hot springs did open up following this earthquakes. The water seems to be around 20C to up 36C. It might be warmer, as details on this are few and little.
Best to my knowledge there is no known volcanoes in this area and have not been in the past ~65 million years or longer.
