Up to 480-Meter Tsunami Flooded Alaskan Fjord in 2025, Researchers Reconstruct

A dramatic natural event, a megatsunami reaching an astonishing height of up to 480 meters, struck Alaska's Tracy Arm Fjord on August 10, 2025. Researchers have meticulously reconstructed this colossal wave, which ranks as the second-highest ever recorded globally. The fjord, a popular destination for cruise ships and excursion boats, typically teems with thousands of passengers during the summer season. By sheer luck, the megatsunami occurred in the very early morning hours, before the daily influx of tourists. Had the event transpired just a few hours later, the consequences could have been catastrophic, potentially leading to numerous casualties. The remote location and the timing of the wave's impact were fortunate circumstances that prevented a major disaster. This event serves as a stark reminder of the powerful and unpredictable forces of nature, particularly in geologically active regions like Alaska, and highlights the importance of understanding and monitoring such phenomena, even in areas frequented by human activity.
