Warming Climate Threatens Rise of Destructive Lake Tsunamis in Alaska

Climate change is causing a surprising increase in a rare hazard in Alaska: lake tsunamis. These powerful waves, triggered by landslides in glacial lakes, pose a growing threat to communities near these scenic bodies of water.

Climate change triggers rare lake tsunamis in Alaska due to melting glaciers and thawing permafrost. New study highlights the need for early warning systems to protect communities from these powerful waves.

A recent study by geologist Bretwood Higman of Ground Truth Alaska highlights this emerging danger.  Melting glaciers and thawing permafrost are destabilizing slopes surrounding lakes, making landslides more likely.  

While past incidents have occurred in remote areas,  Higman warns that populated areas like Portage Lake near Whittier could be next.

Higman emphasizes the need for further research to assess risks and develop early warning systems.  By analyzing seismic signals preceding landslides, scientists hope to predict these events and protect communities.

The increasing frequency of lake tsunamis serves as a stark reminder of the far-reaching consequences of climate change.  

Understanding these risks is crucial for safeguarding lives and infrastructure in Alaska and other regions with similar geological features.
