Volcano hazards from Mount Rainier, Washington
Mount Rainier—at 4393 meters (14,410 feet) the highest peak in the Cascade Range—is a dormant volcano whose load of glacier ice exceeds that of any other mountain in the conterminous United States. This tremendous mass of rock and ice, in combination with great topographic relief, poses a variety of geologic hazards, both during inevitable future eruptions and during the intervening periods of rep

Experimental studies of deposition at a debris-flow flume
Geologists commonly infer the flow conditions and the physical properties of debris flows from the sedimentologic, stratigraphic, and morphologic characteristics of their deposits. However, such inferences commonly lack corroboration by direct observation because the capricious nature of debris flows makes systematic observation and measurement of natural events both difficult and dangerous. Furth

History and hazards of Mount Rainier, Washington
Mount Rainier is an active volcano that first erupted about half a million years ago. Because of Rainier's great height (14,410 feet above sea level) and northerly location, glaciers have cut deeply into its lavas, making it appear deceptively older than it actually is. Mount Rainier is known to have erupted as recently as in the 1840s, and large eruptions took place as recently as about 1,000 and

Pay a little now, or a lot later
Odds are 2-in-3 that at least one disastrous earthquake will strike the San Francisco Bay Area before 2020. Faced with this threat, corporations and government agencies have stepped up efforts that will reduce future losses by billions of dollars.

Building safer structures
In this century, major earthquakes in the United States have damaged or destroyed numerous buildings, bridges, and other structures. By monitoring how structures respond to earthquakes and applying the knowledge gained, scientists and engineers are improving the ability of structures to survive major earthquakes. Many lives and millions of dollars have already been saved by this ongoing research.

Exploring storm surge
This video provides a thorough discussion of storm surge, one of the most dangerous elements of hurricanes and major storms. This video illustrates basic storm surge principles, shows actual footage of storm surge damage and relates high-water level data collection by the U.S. Geological Survey to the task of recreating the storm surge event.

Estimating heat capacity and heat content of rocks
New heat-capacity measurements are reported for four rock types; Westerly granite from Bradford, RI, andesite from Lake County, OR, peridotite from Sonoma County, CA, and basalt from the Columbia River Group. Measurements were made on powders of the rocks in the temperature range of 340 to about 1000 K.
Our measured heat-capacity values for rocks and other measurements of heat capacity or heat con
