Alaska’s near-record landslide tsunami sent a wave 1,580 feet up the fjord walls Read Full Article #AlaskaNews #Landslide #Tsunami2024
🏔️ A massive landslide into Tracy Arm fjord on Aug. 9, 2025, triggered the second-highest recorded tsunami, sending water and debris 1,580 feet high.
⚠️ Landslides at retreating glacier terminals, like the one at Tracy Arm, are an increasing hazard across the Arctic due to rapid uplift and ice loss combined with erosion.
🚨 A potential alert system could have warned ships and coastal areas days in advance, using seismic tremors and weather data to issue "yellow" and "orange" alerts, followed by a "red" alert for an event in progress.

A 27-year study across Alaska found soils are warming at considerable depths, with permafrost regions warming fastest at 0.64°C per decade, while 100% of monitoring stations showed warming 4 feet underground, raising concerns about permafrost thaw, carbon…
🌡️ Alaska's air temperatures are rising twice as fast as in the contiguous U.S., with recent research revealing significant soil warming across the state.
📉 A 27-year study (1997-2023) analyzed data from 43 weather stations, finding that average annual soil temperatures increased significantly across all permafrost regions. The fastest warming rates were observed at higher latitudes.
🌲 Soil warming was observed across the entire soil profile, with no significant differences in warming rates based on depth. The presence and depth of snow significantly influenced the relationship between air and soil temperatures, buffering soils from extreme air temperatures in winter.
