When Geological Processes Collide– Exploring the Link Between Earthquakes and Glaciers

What happens when glaciers melt? Scientists have discussed numerous effects of deglaciation including sea level rise and loss of habitats but recently, geologists have been thinking about how glaciers interact with the crust of the earth. Researchers from the University of Alaska, Fairbanks found a link between melting glaciers and earthquakes in Southeast Alaska which adds new understanding about the indirect effects of climate change and the role of humans in natural disasters.

Movement data from populations of ringed seals and white whales before and after a major sea-ice decline provides insight on how each species has responded to habitat loss. One of these species has chosen retreat, while the other has learned to adapt.
