Using geoscience to help understand whether health risks lurk in particles produced by disasters

By Geoff Plumlee, Research Geochemist 

Video Highlights:

* A catastrophic 1982 rainstorm triggered 18,000 landslides in the Bay Area, claiming 25 lives and causing \$66 million in property damage

* The combination of steep slopes, weak rocks, and intense winter storms make Bay Area uplands an ideal setting for landslides

Past, Present, And Future

Grizzly bear and her cub visit a bear hair trap in Glacier National Park. The bear leaves hair samples snagged on the barbed wire as it enters and exits the site. Both bears vigorously rub in the lure pile which is a pile forest debris that had a liquid scent lure poured on it.

Sea Otters and Ecosystem Dynamics in the Aleutians and the Commander Islands

By Tim Tinker, Research Biologist, University of California, Santa Cruz 

This is two video clips captured at the same site from two different angles. The rub trees are on one side of the trail and the excavated log is on the other side. Bears that rub on one or more of the trees often visit the log as well.

As part of the assessment of the binational San Pedro aquifer, the effects of urbanization on runoff in ephemeral streams was studied. Ephemeral streams are those that flow in response to precipitation. Runoff in tributaries to the San Pedro River is important in understanding the water budget of the river.

Black bear cub awkwardly rubs on a bear rub tree regularly used by bears in Glacier National Park.

A wolf feeds on a road-killed elk carcass in the morning. A grizzly bear with two cubs feeds on the carcass in the evening. A grizzly bear will chuff and pop its jaw when it feels threatened. Sometimes it will also charge at the threat, usually veering off or stopping short -- a bluff charge.
