Alaska landslide and glacier retreat produce a measured tsunami 1,580 feet high
A 1,580-foot wave, nearly three times the height of the Space Needle, surged up an Alaskan mountainside hours after tourists departed, marking the second-largest tsunami ever measured. The trigger was a landslide, but the warning signs were already written in the landscape: rapid glacier retreat, heavy rainfall, and thousands of small seismic tremors. This is empirical evidence that melting ice destabilizes more than sea levels. As glaciers withdraw, mountainous coasts face a growing, measurable risk. Understanding drives protection.
Arctic Glacier Retreat Creates New Coastal Lagoons, Expanding Ecosystems
Retreating glaciers across the Arctic are redrawing coastlines, and Svalbard now hosts a growing number of coastal lagoons where none existed before. These newly emerged paraglacial systems remain largely absent from regional monitoring, despite their rapid expansion. We see this as a missed opportunity: the lagoons form a developmental continuum, from glacier-influenced basins to biologically structured systems, and early evidence suggests they act as biogeochemical reactors, including potential methane sources.
