Prof. Peter Robertson to give Free CPT Webinar on February 2, 2015 through ISSMGE

The International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) is launching its first Webinar of the year on February 2. This upcoming webinar on Cone Penetration Testing will be given by CGS Member Prof. Peter Robertson (from Gregg Drilling - California USA). All ISSMGE webinars are offered free of charge in an effort to assist geotechnical engineers worldwide and to promote our profession. You are welcome to attend and highly encouraged to invite all geotechnical & civil engineers and students to participate. This Webinar will be launched on February 2 at 12 noon GMT (4:00 am PST and 7:00 am EST in Canada). lt will then be followed by a 2-day Q&A session that, like the webinar video, can also be viewed anytime later on the ISSMGE Website.

FHWA Geotechnical Team and NHI will offer training in a virtual worldEconomic times have been hard for federal, state and local transportation agencies as well as industry representatives since the recession started.  Getting approval to travel for conferences or training classes has been difficult if not impossible.  The Geotechnical Team at the FHWA and the National Highway Institute (NHI) has come up with a solution to that problem by offering training in an online virtual environment. In the near term they will be offering a tour of the virtual training venue and technology showcase and plan to have more demos in the coming months.  They will offer the first training at the March 2015 International Foundation Congress and Equipment Expo (IFCEE) in San Antonio, Texas.

Underground mine ventilation plan

Underground metal mines can have extremely high temperatures, making it hazardous for employees to work there for more than a few minutes at a time. Researchers from my alma mater, the University of Arizona, are studying the possibility of using a common mining waste product, tailings, as aggregate in shotcrete with good insulation properties that will be used to coat rock surfaces that readily conduct heat.

DIGGSML Standard Data Framework Model

DIGGSML is an XML-based schema designed for transfer of geotechnical and geoenvironmental data between different organizations. In 2013, the ASCE Geo-Institute was awarded a 2-year contract by the Ohio DOT to implement DIGGS. The current version, 2.0a, is undergoing pilot testing through early 2016.

LiDAR Topography of Oso Landslide showing amount of elevation change

The cover story in the latest issue of LIDAR Magazine is titled Unearthing Landslides. It describes the work done by a company called Quantum Spatial in the immediate aftermath of the Oso Landslide. They were also involved in scanning the recent landslide in Grand Mesa, Colorado. Quantum Spatial has developed a landslide tool that identifies areas of landslide risk based on different aspects of the LiDAR based topography. [Source: Read the article from LiDAR News.

NASA Radar System Surveys Napa Valley Quake Area PDF Print E-mail

NASA's C-20A Earth science research aircraft with the UAVSAR slung underneath its belly lifts off the runway at Edwards Air Force Base on a prior radar survey mission.

Scientists from NASA's Jet Propulsion Laboratory in Pasadena, CA used their Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) technology to collect repeat measurements of the Napa Valley area to accurately map ground deformations from the August 24, 2014 earthquake. The special autopilot developed by NASA allows the C-20A aircraft to fly within 30 feet of its previous flight line surveys to collect high-resolution radar data. The data can be processed using interferrometric techniques to generate INSAR images that will tell geologists, engineers, seismologists, and planners how much movement occurred, including in soft sediment areas near the North Bay Aqueduct.
