Monitoring Sacramento River Levees with Radar?
April 10, 2014 | NASA

“In the Sacramento River delta north of San Francisco Bay, islands, agricultural lands and communities below sea level are protected from surrounding water channels by more than 1,100 miles of dirt levees, many of which date back to the California Gold Rush.” NASA now has a method to monitor them using radar. Quote from the NASA press release.

What Your Homeowner’s Insurance Does Not Cover
March 4, 2014 | Geology.com

Most homeowners insurance policies have exclusions that make them worthless when the home is damaged by common geologic problems such as floods, earthquakes, landslides, mine subsidence, cavern collapse and expansive soils. When a home is damaged the homeowner often is surprised that his “all perils” policy has these exclusions.

The Seti River Disaster
January 28, 2014 | NASA Earth Observatory

The first sign of trouble for residents along the upper Seti River in Nepal was the water. In late April and early May 2012, what was usually a roaring river had slowed to a trickle. And the milky-white water—colored by rock flour from glaciers upstream in the Sabche Cirque—had turned blue and clear. Residents regarded the river changes as bizarre, but nobody connected the slowdown to anything dangerous upstream. So it came as a surprise when a slurry of sediment, rock, and water suddenly surged through the valley on May 5, 2012, obliterating dozens of homes and sweeping 72 people to their deaths.

Floods and Landslides in Brazil
January 2, 2014 | NASA Earth Observatory

December rainfall in Espirito Santo has already reached 714 millimeters (28.11 inches), an all-time record monthly rainfall.”

Megafloods in Idaho and on Mars
December 26, 2013 | Caltech

“South-central Idaho and the surface of Mars have an interesting geological feature in common: amphitheater-headed canyons. These U-shaped canyons with tall vertical headwalls are found near the Snake River in Idaho as well as on the surface of Mars. Various explanations for how these canyons formed have been offered—some for Mars, some for Idaho, some for both. [...] Kenneth A. Farley offers a plausible account that all these canyons were created by enormous floods.” Quoted from the Caltech press release.

NASA Hazard Warning Systems
December 12, 2013 | NASA

What is a Storm Surge?
November 3, 2013 | Geology.com

A storm surge is a mound of water produced when a hurricane moves across a large body of water. Driving wind “pushes” the water so quickly that it “piles up” on the water in front of it, producing a mound of water that can be much higher than normal sea level.

Natural Hazard Viewer for Arizona
September 24, 2013 | Arizona Geological Survey

The interactive Natural Hazard Viewer focuses on four hazards common to Arizona — geologic faults and earthquakes, earth fissures, floods and wildfire. Each hazard is described in detail and displayed as a layer on a map. Moreover, the natural hazard information is dynamic; site updates will occur as new or revised hazard data becomes available.

Editor’s Comment: Every state geological survey should have one of these!

At the time, the river was more than six feet above flood stage, down from more than eight feet above flood stage.” Quoted from the NASA Earth Observatory image release.

The report, Coastal Impacts, Adaptation, and Vulnerabilities: a technical input to the 2013 National Climate Assessment, authored by leading scientists and experts, emphasizes the need for increased coordination and planning to ensure U.S. coastal communities are resilient against the effects of climate change.” Quoted from the USGS press release.

National Climate Assessment
January 25, 2013 | U.S. Global Change Research Program

“Climate change is already affecting the American people. Certain types of weather events have become more frequent and/or intense, including heat waves, heavy downpours, and, in some regions, floods and droughts. Sea level is rising, oceans are becoming more acidic, and glaciers and arctic sea ice are melting. These changes are part of the pattern of global climate change, which is primarily driven by human activity.” Quoted from the Executive Summary of the Federal Advisory Committee Draft Climate Assessment Report
