Retreating Glacier May Trigger Catastrophic Alaska Tsunami

NEW YORK NY

Climate change has increased the risk of a huge landslide in an Alaskan fjord that could cause a catastrophic tsunami, scientists said Thursday. Warming temperatures have caused the retreat of a glacier that helps support a steep, mile-long slope along one flank of a fjord in Prince William Sound, about 60 miles east of Anchorage. With only a third of the slope now supported by ice, the scientists said, a landslide could be triggered by an earthquake, prolonged heavy rain or even a heat wave that could cause extensive melting of surface snow.
