A home collapses into the Mendenhall River on Saturday due to a record amount of flooding from Suicide Basin since an annual cycle of water release began there in 2011. Officials said nobody was injured when the house collapsed, but other structures along the riverbank are at risk. (Screenshot from video by Sam Nolan).
Juneau resident James Wycoff noticed on his regular walks to Nugget Falls that the face of the glacier seemed to be retreating faster this year than he’s ever seen before. The Mendenhall Glacier’s terminus retreated more than 800 feet.
Scientists believe a massive glacial dam release - or jökulhlaup - recently occurred in Southeast Alaska. But they probably would not have known about it if they had not been tipped off by an observant commercial fisherman.
Weather authorities and residents are getting used to responding to glacial floods in the Mendenhall Valley.
The torrential rain, exceptional even by Juneau’s standards, comes courtesy of Typhoon Lan, whose remnants have left Asia.
There is some evidence that shifts in the weight on a land mass can affect earthquakes — and glaciers are receding around the world — but seismologists and glaciologists simply cannot “connect the dots” between the two happenings.
