A Slippery Slope: Warm rains and glacial melting trigger dangerous debris flows MELTING MOUNTAIN glaciers and warming rains drive debris flows, torrents of mud and rock that have damaged roads, closed recreational facilities and led to millions of dollars in clean-up costs in the Northwest. Climate change is likely to increase risks in the future. [...]

New Zealand earthquake damage illustrates risks from crustal faults | News & Research Communications | Oregon State University. Even though this earthquake was weaker than last year’s event, it was much shallower; was situated directly under Christchurch; hit during the lunch hour when more people were exposed to damage; and shook sediments that were prone [...]
Cascadia Roulette: The odds are good that a major earthquake will strike the Pacific Northwest in the near future. We’re overdue, says Robert Yeats. Celene Carillo terra Magazine Bob Yeats would like you to know he cannot predict earthquakes. He is not prophetic. He claims no association with the supernatural. He can’t tell you when disaster [...]
[youtube=http://www.youtube.com/watch?v=Qu4uNoaiMjs&fs=1&hl=en_US] An Oregon State University research program has returned to Collier Glacier for the first time in almost 20 years and found that the glacier has decreased more than 20 percent from its size in the late 1980s. The findings are consistent with glacial retreat all over the world and provide some of the [...]

From the Eugene Register Guard: Researchers led by a professor at Oregon State University said they finally have confirmed what some scientists have believed for some time: that the last ice age ended because of a slight shift in the Earth’s orbit. The findings could help scientists predict how the planet’s remaining ice will be [...]
Earlier this year, Ph.D. student Logan Mitchell spent two months working at the Western Antarctic Ice Sheet (WAIS) Divide research station in Antarctica. Now, Ph.D. student Julia Rosen will spend three weeks this summer at the North Greenland Eemian Ice Core Drilling Project (NEEM), and she will continue the blog. Julia took some photos from [...]
For teachers planning to focus on volcanoes this year, see this Web site maintained by Dr. Shan de Silva, professor of geosciences at Oregon State University. The site includes curricula, a kids page, a blog about ongoing volcanic activity and a world map showing volcano locations.
There is evidence that this current has shut down with some regularity in the past — and sometimes quite rapidly — in response to large influxes of fresh water from melting glaciers. However, it appears as though the current rate of glacial melt is occurring at a more gradual pace which will “give ecosystems more [...]
