Alaska's Tracy Arm Tsunami: A Climate-Driven Geological Catastrophe
In August 2025, a massive tsunami occurred in Alaska's Tracy Arm Fjord, reaching a height of 481 meters, making it the second-largest tsunami ever recorded. The event was triggered by the retreat of the South Sawyer Glacier, which had been holding a mountainside in place. As the glacier retreated, it exposed unstable rock that eventually collapsed into the fjord, creating the tsunami. This incident highlights the direct impact of climate change on geological stability, as the glacier's retreat was a key factor in the mountainside's collapse. Despite the tsunami's size, no lives were lost, partly due to the timing of the event.
