Four people are feared dead after tsunami waves struck the coast of Greenland on Saturday night.

A 4.1-magnitude earthquake, which struck 28 kilometres north of the northwest village of Nuugaatsiaq, is believed to have triggered the tsunami, according to a report from Kalaallit Nunaata Radioa, the national broadcaster in Greenland.

KNR says Nuugaatsiaq has been evacuated, adding that the waves also struck the communities of Uummannaq and Illorsuit. A helicopter and boats have been deployed to assist in the search-and-rescue effort.

Residents took to social media to post videos of the flooding.

The BBC is reporting a total of 39 people have been evacuated from Nuugaatsiaq. A number of injuries have also been reported.

Many residents in Nunavut have family ties in Greenland, which has a population of about 56,000.
