When controlling for other environmental variables, we find that glaciers within 5 km of an active volcano have median velocities 46% greater than those of other glaciers and that, for glaciers near active volcanoes, velocities further increase with proximity to the volcano.

A figure showing box plots of median glacier velocities for glaciers near a volcano (in pink) and other glaciers (in blue). Data is grouped by glacial region, and shows that the velocities of glaciers near volcanoes are typically greater than those of other glaciers in 9 of the 10 regions.

I'm pleased to announce our exciting new paper in Comms Earth & Environment: 'Proximity to active volcanoes enhances glacier velocity', in which we find glaciers located near volcanoes flow almost 50% faster than those located elsewhere. @natureportfolio.bsky.social
