Why Mega Tsunamis Keep Happening in Greenland

Mega tsunamis in Greenland are no longer rare geological anomalies. In recent years, massive landslides collapsing into narrow fjords have generated waves hundreds of metres high, including the 200-metre Dickson Fjord tsunami that caused the Earth to vibrate for days. This article explores how and why these Greenland mega tsunamis occurred, what damage they caused, and why warming temperatures, melting glaciers, and destabilised slopes mean similar events are likely to become more common in the Arctic and beyond.
