Oso Disaster Had Its Roots In Earlier Landslides
vinces99 writes: The disastrous March 22 landslide that killed 43 people in the rural Washington state community of Oso involved the "remobilization" of a 2006 landslide on the same hillside, a new federally sponsored geological study concludes. The research indicates the landslide, the deadliest in U.S. history, happened in two major stages. The first stage remobilized the 2006 slide, including part of an adjacent forested slope from an ancient slide, and was made up largely or entirely of deposits from previous landslides. The first stage ultimately moved more than six-tenths of a mile across the north fork of the Stillaguamish River and caused nearly all the destruction in the Steelhead Haven neighborhood. The second stage started several minutes later and consisted of ancient landslide and glacial deposits. That material moved into the space vacated by the first stage and moved rapidly until it reached the trailing edge of the first stage, the study found. "Perhaps the most striking finding is that, while the Oso landslide was a rare geologic occurrence, it was not extraordinary," said Joseph Wartman, a University of Washington associate professor of civil and environmental engineering and a team leader for the study.
It's a bear. What comes around, goes around.
This issue is a bit more complicated than you think.
To summarize the summary: "The most striking finding is that...it was not extraordinary."
Not to belittle the loss of those involved but it's always a bit much that 43 dead in the US = catastrophe. If this had happened in Asia or Africa it wouldn't make the news unless hundreds or thousands had been killed.
blindly antisocialist = antisocial
How many furlongs would that be?
I don't live there, but looking at some of the photos, is deforestation potentially part of the problem? Honest question for which I expect to be flamed by some.... but there it is.
When I was little toddler I was fascinated by an hourglass --- particularly on the almost hidden but still perceivable pattern of a new slide happened on the back of an ancient slide
Many things that we observe, even from something as tiny as the sandslides inside an hourglass, can be magnified many folds, and still hold true
Muchas Gracias, Señor Edward Snowden !
It's possible to map ground contours using SAR through vegetation. And it would be trivially easy to make property purchases conditional on a risk assesment of landslide conditions basd upon past slide activity. There goes the market for those cheap riverfront vacation properties.
Have gnu, will travel.
I really like how instead of intelligent discourse about the triggers for the landslide and any possible ways to prevent/predict future landslides, people latch on to one phrase, and use it to belittle the media or other political stances. It's like those Christian right-wing people obsessively throwing the word "hypothesis" around to justify their idiotic creationist beliefs. Was it a tragedy? Yes. Was it a disaster? Yes. Is that was this discussion is about? No. Please take it somewhere else, so we can continue to discussion.

They that can give up essential liberty to obtain a little temporary safety deserve neither safety nor liberty.

Pages 146 and 147 of the linked report go into the associations to timber cuts. They indicate positive correlations and previous reports have fingered this effect at the same exact site. Citations are provided in the report.
The amount timber harvests contributed was "beyond the scope of our reconnaissance effort", but the citations provide somebody with an interest with a way to see what other reports that did have it within scope have said.
Thanks for your thoughtful comment. I support the transgendered community and certainly don't consider them liars. But it seems very unlikely that Jane/Lonny Eachus is part of that community. If I'm wrong then I'll apologize, retract my accusations, and support Lonny Eachus as she transitions to Jane.
