Geotechnical centrifuge at the UC Davis Center for Geotechnical Modeling

How would you feel if you were subjected to 75Gs of centrifugal force? Well, at least you would know what the soil feels like in some of the cutting edge geotechnical modeling being done at the UC Davis Center for Geotechnical Modeling (CGM). This article is a fascinating overview of the history of the lab, and the types of geotechnical experiments they can run using the 9 meter radius centrifuge. It can spin a 5-ton payload at 90 revolutions per minute! No other lab in the world can boast those numbers. [Source: Read the full blog post from the College of Engineering at UC Davis.

Modified from the YouTube description: Video of a DeWind One-Pass Trencher installing a Soil-Bentonite Wall 55' deep. This is a mix in place technology capable of installations up to 125' feet deep. The soils are evenly homogenized with the additives from top to bottom and from start to finish. An Average of 300 LF installed per day. No messy mixing ponds, open excavations, very little spoils, One piece of equipment and only 4 men are required for this 5000 LF installation reducing safety exposure.

The Earthquake That Will Devastate Seattle PDF Print E-mail

The next full-margin rupture of the Cascadia subduction zone will spell the worst natural disaster in the history of the continent.

This is a fantastic article by Kathryn Schulz for New Yorker Magazine on the seismic and tsunami hazards associated with the Cascadia Subduction Zone in the Pacific Northwest. Ms. Schulz paints a very vivid picture of what the devestation will look like based on input from many people who know what they are talking about, geologists, seismologists, FEMA officials, and State and Local disaster planning folks. This article was so effective, that NPR reported a run on survival kit supplies in Northwest U.S. The article also does a nice job explaining the interesting geologic detective work to connect the dots on the last major earthquake and Tsunami to strike that area in January of 1700. Highly recommended reading. What did you think of the article? Leave a comment below. [Source: The New Yorker via AEG Insider.

Proposed glass bridge in China's Zhangjiajie National Forest

Check out this proposed bridge in China's Zhangjiajie National Forest. It has a span of 1,200 feet and is over 1,300 feet off the ground. The majestic landscape was reportedly the inspiration for the Halleluja Mountains of James Cameron's movie Avatar. The bridge architect that designed it initially refused saying the landscape was too beautiful to put a bridge there. But agreed only if they could design a bridge that would 'disappear'. The 20 foot wide platform is slated to host fashion shows, and the center of the structure will be used for bungee jumping! [Source: Wired. Image: Wired]

Kord Wissman, President of Geopier Foundation Company

National Driller magazine had a nice article not to long ago interviewing Kord Wissman about his transition from consulting to contracting. Kord is the President of Geopier Foundation Company (owned by Tensar). He has some very interesting insights, it's worth the read. I admire Kord as well for his involvement with the Geo-Institute and the GBA, he is very generous with his time and talents, more of us should be like him! I think GBA members can listen to his 'Going to the Dark Side' presentation (which was the impetus for the interview) for free, check the GBA website. [Source: Read the interview at National Driller.

New Geo-Institute Website

From the G-I eUpdate Newsletter:

The Geo-Institute is proud to announce the launch of its new website! With the same URL as before, www.geoinstitute.org, the website strives to support and communicate the value and dynamism of the geoprofession, preserve its integrity, and foster its growth.

Our easy-to-use website features efficient navigation and search, making our most popular and newest content easy to find. The appealing, new design allows GEOSTRATA articles to be easily accessed and indexed by subject.

The G-I website also hosts autonomously maintained "microsites" for committees and chapters; this allows all the individual websites to be located in one place and fosters communication within the G-I community.

The website looks great. Yours truly served on a task force to provide input on selecting a consultant and various design features. I know it will be a tremendous resource for our profession for many years! [Source: Visit the Updated Geo-Institute Website via G-I eUpdate Newsletter. Image: G-I via ShrinkTheWeb]
