Massive Alaska megatsunami was second largest ever recorded

A megatsunami in southeast Alaska last summer reached nearly 500 metres in height, making it the second tallest ever recorded, after 64 million cubic metres of rock broke loose from a mountain and crashed into Tracy Arm Fjord. Scientists determined that small earthquakes triggered the massive landslide, which occurred in the early morning hours and narrowly avoided hitting tourist cruise ships that would have been in the area during daylight. Researchers warn that the event, linked to melting glaciers, highlights the growing danger of such catastrophic waves and express concern about the risk of a similar event occurring when people are present.
