A 6.6 magnitude earthquake was detected off the eastern coast of Greenland, the US Geological Survey reported. No damage or injuries were reported. The epicenter was recorded at a depth of 8.6 kilometers in the Norwegian Sea, some 93 kilometers northwest of the town of Olonkinbyen on the Norwegian island of Jan Mayen. The island has no permanent population. A research station is located there, which was housing about 50 people when the quake occurred. The station’s workers are all involved in research and maintenance at the facility, Erik Persheim, an electronics engineer at the station, told the AP. The station normally houses about 18 engineers and other personnel, he said.
