Megatsunami risk on the rise as glacial melt drives landslides

Geoscientists studying 200m-high wave that hit Greenland coast last year warn of potentially disastrous impactJust under a year ago, the east coast of Greenland was hit by a megatsunami. Triggered by a large landslide entering the uninhabited Dickson Fjord, the resulting tsunami was 200 metres high - equivalent to more than 40 double-decker buses.Luckily no one was hurt, though a military base was obliterated. Now analysis of the seismic data associated with the event has revealed that the tsunami was followed by a standing wave, which continued to slosh back and forth within the narrow fjord for many days.
