Short summary
Glaciers flowing into the ocean sometimes release huge pieces of ice and cause violent tsunami waves which, upon landfall, can cause severe destruction. During an exceptionally well-documented event at Eqip Sermia, west Greenland, the collapse of a 200 m high ice cliff caused a tsunami wave of 50 m height, traveling at a speed exceeding 100 km h−1. This tsunami wave was filmed from a tour boat, and was simultaneously observed with several instruments, as was the run-up of 15 m on the shore.
