Some of the most remote settlements on the planet have been hit by a tsunami that followed a 4.1 magnitude earthquake. Four people are missing in the village of Nuugaatsiaq on Greenland's northwest coast, where the wave swept their home into the ocean, the CBC reports. Some 11 homes were also swept away and around 40 people have been evacuated from the village, reports the BBC. At least two other villages in the area were also affected. Officials believe the tsunami may have been a local one generated by an undersea landslide caused by the earthquake rather than the quake itself, meaning it is unlikely to travel long distances and cause damage in the Canadian Arctic.
