Glacial dam outburst floods Alaska's capital, damages homes

More than 100 homes in Alaska's. capital Juneau have actually been harmed by a glacial dam outburst north. of the city, a progressively frequent phenomenon worsened by. climate modification.

The flooding began on Monday night after water spilled out. from the glacial lake at Suicide Basin, which yearly fills. with rainwater and meltwater and is normally dammed by the. retreating Mendenhall Glacier. If enough water fills the basin,. it can rupture through or overtop the ice damming it in.

The overflow crested at about 3 a.m. on Tuesday, with the. Mendenhall River at 15.99 feet, the National Weather Condition Service. said. The river's levels had dropped back to regular by. Wednesday.

Local authorities had actually cautioned residents near the river to. take safety measures and opened a local school as a shelter. City. officials stated no injuries have actually been reported.

The flood came almost precisely a year after a record-breaking. glacial dam outburst at Suicide Basin triggered comparable flooding. In 2023, the Mendenhall River crested at 14.82 feet, the. National Weather condition Service stated.

The risk of glacial dam outbursts has actually been worsened by. manufactured environment modification, which triggers glaciers to retreat and. has increased the number and size of glacial lakes.

The U.S. Geological Study has actually monitored the Suicide Basin. given that 1965 but it was not until July 2011 that a glacial dam. outburst was taped. Since then, the basin has burst more than. 30 times, the National Weather Service said.
