Latest News About Megatsunami

Here’s a concise update on the latest megatsunami news as of now.

• Alaska megatsunami update: A recent analysis suggests a megatsunami in Tracy Arm Fjord was triggered by a large landslide caused by tiny earthquakes, and it is considered one of the largest events on record. Some cruise operations have indicated changes to routes in response to such events. This reflects ongoing monitoring and safety adjustments for coastal regions at risk.

Illustration: A simple way to visualize a megatsunami risk is a coastal region with a high cliff/fiord system upstream where a landslide suddenly displaces a large volume of water, generating a massive wave that propagates toward the shore.
