A massive megatsunami in southeast Alaska, caused by a mountain collapse into the sea, was the second tallest ever recorded, reaching nearly 500 meters. This event, which occurred last summer, was triggered by small earthquakes that led to a landslide of 64 million cubic meters of rock into a fjord. Fortunately, it happened early in the morning, avoiding potential disaster for nearby tourist cruise ships. Dr. Bretwood Higman, an Alaskan geologist, noted the close call and expressed concern about future risks. Megatsunamis like this are typically localized, unlike oceanic tsunamis that can travel vast distances. Alaska’s geography, with steep mountains and frequent earthquakes, makes it particularly susceptible to such events. Recent research indicates that climate change and glacier melt are exacerbating these collapses. Dr. Stephen Hicks highlighted that retreating glaciers can destabilize rock formations, increasing the likelihood of landslides. As more tourists visit remote areas, understanding and mitigating these risks becomes crucial.
