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.

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]

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.

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]

What will 2015 hold for the tunneling industry? Tunnel Business Magazine asked a panel of 4 industry experts that question. The panel consisted of a Colorado School of Mines Professor as well as reps from Black and Veatch, AECOM, and Kenall Manufacturing. In general they seem to agree that there are opportunities in the US for large combined sewer outfall (CSO) projects, water distribution projects, and even high-speed rail, particularly in California.

A team from Northeastern University has a very interesting van used for quantitatively assessing pavement condition using a variety of sensors. They use cameras, laser profilers, accelerometers on axles, pressure sensors in the tires, microphones, and even ground penetrating radar. The researchers reportedly characterized pavement condition of 150 miles of road in 4 days in Beverly, Massachussets, a task that took public employees about 1 year the last time it was performed, in 2010. The cost of the survey was around $25,000. The technology is expected to be commercialized this month. [Source: The Boston Globe. Image: Boston Globe]
