Quick look:
The magnificent camellias, rhododendrons, azaleas, and magnolias that create a spectacular display of color each year at the U.S. Geological Survey in Menlo Park aren't what usually come to mind when one thinks about a government building and its landscaping. The lush plantings and many rare specimens are largely the work of the late USGS geophysicist, Howard Oliver....Camellias, Rhododendrons Grace Government Offices

Quick look:
According to newly updated information from members of the 1868 Hayward Earthquake Alliance, a major earthquake on the Hayward fault would impact more than 5 million people and property and contents valued in excess of $1.5 trillion in the six counties surrounding the fault. If the 1868 earthquake were to reoccur today, Risk Management Solutions (RMS) estimates total economic losses to residential and commercial properties would likely exceed $165 billion. Other factors, such as fire, damage to infrastructure and related disruption would substantially increase the loss...The Hayward Fault: America's Most Dangerous?

The U.S. Geological Survey, in cooperation with the San Antonio Water System, conducted a 4-year study during 2002?06 to identify major flow paths in the Edwards aquifer in northeastern Bexar and southern Comal Counties (study area). In the study area, faulting directs ground water into three hypoth...Geologic, Hydrologic, and Geochemical Identification of Flow Paths in the Edwards Aquifer, Northeastern Bexar and Southern Comal Counties, Texas

A geophysical characterization of a portion of American River levees in Sacramento, California was conducted in May, 2007. Targets of interest included the distribution and thickness of sand lenses that underlie the levees and the depth to a clay unit that ...Geophysical Characterization of the American River Levees, Sacramento, California, using Electromagnetics, Capacitively Coupled Resistivity, and DC Resistivity

Drought: the Long, Slow Natural Hazard (Part 2) Quick look:
In the second part of our two-part drought mini-series, we head down South to talk with USGS scientists Curtis Weaver and Brian McCallum about the drought situation in the Southeastern United States. We also learn some eye-opening economic implications of drought. (Did you know that it's possibly the most expensive natural hazard to address?)
