Geologic map of a portion of the lower Mississippi River

This is a very nice little article on the geomorphology of the Mississippi River for the layman. But it was definitely the geologic map that caught my eye. Isn't it great? Probably nice enough to hang on your wall. [Source: Scienceline. Image: Scienceline]

 
Finland's Nuclear Waste Storage Plans PDF Print E-mail

As the U.S. continues to fight over hurdles for its Yucca Mountain Nuclear Waste repository, Finland is on track to become the first country with a permanent storage facility for spent fuel rods from nuclear reactors. Their Onkalo tunnel, on the western coast of Finland will eventually stretch for 5-km (2-miles) and reach a depth of 500-m (1,600-ft) in solid granite bedrock. Once at depth a grid of horizontal tunnels will be constructed. Vertical storage holes will be excavated in these horizontal shafts, and the spent rods, encased in steel cannisters with copper corrosion protection, will be placed on layers of bentonite clay. The clay will cushion the cannisters and protect them against long term geologic movement. The clay also serves as a barrier to water, swelling in its presence to seal off any cracks or conduits for water that could potentially transport nuclear contamination in the distant future if the primary measures of protection are compromised. The tunnels will eventually be backfilled with bentonite and rock. The facility is projected to open in approximately 15 years at a cost of about 3 billion euros. The projected life of the facility is through 2100.  Links after the break. (Illustration by BBC)

New Dams Being Considered to Handle West's Water Needs PDF Print E-mail
GeoNews - Regional
Written by Randy Post   
Tuesday, 04 March 2008 07:30

An article in the Seattle Post Intelligencer discusses how the era of building massive dams that ended in the late 1960s with the completion of Glen Canyon Dam may be on its way to a resurgence because of booming populations throughout the west and a desperate need for water. This comes at a time when the USBR and other agencies are in the process of tearing down some dams. Of course the environmental hurdles and opposition to new dam projects will likely kill many of the projects before they get started. But in the absence of any kind of limits on population growth, there may not be many other options. Read on to see where major dam projects are being considered. (Photo by Molas)

The historic town of Staufen in southwestern Germany on the western edge of the Black Forest is experiencing some rather unexpected downward movement these days. Several buildings, some of them historic, are experiencing cracking and distress and are still sinking at a rate of approximately 1mm per week. Investigations are underway, but everything seems to point towards drilling operations for geothermal energy which were conducted last fall. [Editor] More after the break...[/Editor]

 

 
Talc Might Lubricate San Andreas Fault PDF Print E-mail

There is currently a major project going on to drill into the San Andreas Fault to better understand the various mechanisms of the fault system. The project is organized and run by SAFOD, the San Andreas Fault Observatory at Depth. Recent cores have shown that a layer of talc is located approcimately 2 miles below the ground surface. Members of the SAFOD speculate that the talc may act as a lubricant for the San Andreas Fault and the occurrence of the layer may explain the absence of sharp earthquakes. Check out the article in the San Francisco Chornicle, and expect to see the full results published in the Journal Nature.

 
Utah to Release Recommendations for Geologic Hazard Regulations for Development PDF Print E-mail

As reported in a previous post, Utah has been considering adopting model legislation for local municipalities to make it more difficult for developers to develop in landslide prone areas. Apparently the Geologic Hazards working group is preparing to issue their recommendations. From Utah's Daily Herald:

A final set of recommendations for regulating development in areas at risk for landslides is expected to be adopted next week.

The Geologic Hazards Working Group is scheduled to meet at 9 a.m. Wednesday in Room 112 at the Department of Natural Resources building, 1594 W. North Temple in Salt Lake City. Gov. Jon Huntsman Jr. formed the group after landslides damaged houses, including some in Utah County, in 2005 and 2006.

Landowners Fight Drilling Near Nuclear Blast Site PDF Print E-mail

In the late 60's and 70's at a site in the western Colorado Mountains, the US Government tried using nuclear explosions at a depth of greater than 8,000 ft to fracture the rock in an attempt to increase natural gas production. The experiments, known as Project Rulison, were not largely successful. Now, nearly 37 years later, land owners are up in arms about a Texas company's proposal to drill natural gas wells closer to the site and its buffer zone and are concerned about possible contamination of surface and groundwater with radioactive material. Read the AP article in Wyoming's Casper Star Tribune.

The San Francisco Chronicle reports that the California State Department of Water Resources indicates the Sierra snow pack is at just 29% of normal leading state officials to start pushing water conservation measures. According to the Governator:

Unless we plan for the future, we will not be able to sustain consecutive drought years and severe water shortages will have a grave impact to our quality of life and California's economy.

A blasting accident in Berryville Virginia involving West Virginia Drilling company Geological Technologies, Inc. is being investigated by the State Fire Marshal's office. The blast, which occured on 4/20/07 (?) sent rock up to 1,200 ft away from the work site where GTI was preparing a foundation for a new structure. There were reportedly no warning sirens before the blast. No injuries were reported and damage estimates have not been released, but several businesses were damaged. (Photo by seaworthy)

An article by the New Orleans Times-Picayune reports that some of the sheet piles used in the levee along the 17th Street Canal are only 4.5-ft below sea level. The US Army Corps of Engineers say they have done "the most extensive technical analysis ever performed" on the drainage canal, but at least one person is not finding comfort in that claim.
