The National Geodetic Data Center (NGDC) of NOAA has an online collection of photos of various geologic hazards. Many of the photos are from older sets of 35mm slides that have been digitized. They are free to use provided you credit the photographer and the NGDC as the source. The would be really useful for educators and for powerpoint presentations. The only drawback is that they are in TIF format and some of them could use some retouching. (Photo by University of Colorado, made available by NOAA/NGDC)
As I’ve reported previously, the State of Utah is in the process of adopting ordinances regulating the development of land that is susceptible to landslides and other geologic hazards. A new bill has been introduced in the Utah House that would give developers a recourse for appeal if they don’t like the decision of a local jurisdiction. More at the Salt Lake Tribune.
A call for volunteers has been made on behalf of Governor Schwarzenegger by way of the California Department of Consumer Affairs website as reported by AEG.

As we mentioned in a previous post, the State of Utah had experienced several slope failures in approved, permitted subdivisions. Those failures prompted the governor to form the Geologic Hazards Working Group (GHWG) to evaluate […]
Is it possible to safely rehabilitate dams in earth fissure risk zones to continue to provide economical flood protection to the public, or does the risk of dam failure due to an undetected fissure present too great a threat to the public? Read the article to find out the view of the Arizona Department of Water Resources.
Anyone who owns a house or is looking to buy one should be aware that nearly all home owner’s insurance policies will not cover them in the event their home is damaged by common geologic processes including floods, landslides, earthquakes, subsidence, and expansive or swelling soils.

Phoenix Arizona’s PBS affiliate, KAET-TV, Channel 8 had a segment on Earth Fissures on their May 30th episode of "Horizons". They interviewed one resident of the Chandler Heights area that has problems with earth fissures on her property. They also interviewed Todd Shippman with the AZGS in the field. Todd is the project manager for the AZGS’ earth fissure mapping program. The bulk of the program was an interview with Lee Allison, the head of the AZGS and the Arizona State Geologist. He explains the earth fissure mapping program, and the planning scale maps that were just released this week on the AZGS Website. Click through for embedded video of the segment from the Horizon Website. You can also download it as a podcast if you wish. (Photo courtesy of NCS Consultants, LLC.)
The Utah Governer’s Geologic Hazards Working Group, which includes no one from the private sector, is considering some model legislation that can be adopted by cities and counties to make it more difficult for developers to build in landslide prone areas. Also, among other things, the group may recommend that Utah adopt stricter grading requirements based on the experiences of California. Read on for more info.
