A tsunami has apparently just hit Greenland.

The police report major floods in the Nuugaatsiaq district. Major waves have also hit Uummannaq and Illorsuit.

Senior Prosecutor at Police Liselotte Bøhn says it is not yet clear what the flood is due to.

There are extensive devastations, but it is not yet clear or how many people have been hurt.

A rescue helicopter has been sent from Uummannaq with police, health care and emergency preparedness, and efforts are being made to send additional resources to the area from Kangerlussuaq. The rescue operation is coordinated in cooperation with rescue preparedness and health services.

If you are in the fjord systems around Uummannaq, you must look up the terrestrial network and stay away from the coastline.

KNR sends extra radio at 00.45 and again at 1.00.

Maybe an undersea run-out landslide?
