In October, 2015, the land gave way in a remote Alaskan fjord letting loose 200 million tons of rock. When the rock entered the sea, it sent a wave 600 feet high up onto the other side. No one saw it, except those monitoring a seismograph at Columbia University in New York. You can read an article about the event here.
