Professor Petley, the author of the Landslide Blog, has an interesting discussion about a controversy in the geoengineering / geology community regarding the Oso landslide in Washington State. The Geotechnical Engineering Extreme Events Reconaissance (or GEER) report was recently issued for the OSO landslide. But USGS scientists have a different theory about the event. Both the GEER committee and the USGS agree that the Oso landslide was a two-fold failure event. But the difference in [...]
According to the Landslide Blog, this rockfall video was taken in Maoxian County in Sichuan Province of China on or around July 17, 2014. It shows a very dangerous rockfall event with people running from their cars. In one scene you can even see someone being struck by a rock and knocked over. The person is later able to walk away with assistance. Towards the end of the video, even the windshield of the videographer is struck by a smaller rock and cracked. Very dramatic and very scary video!
Equipment manufacturer Liebherr has created a new simulator to allow operators to train on foundation drilling equipment virtually. The simulator is based on other simulators created by Liebherr, and includes things like a real construction site with neighboring buildings and structures, uneven ground, varying soil conditions, etc. [Source: Read more at GE Innovation News | New Civil Engineer via @GE_magazine.

Hayward Baker was among the contractors called in for emergency repairs to a failed retaining wall in Baltimore that destabilized a slope, causing a landslide that enveloped cars and threatened a railroad track below. The final episode of the slope failure was caught on video and showed several cars being swallowed. GeoPrac sponsor, Hayward Baker is currently on-site installing a temporary soldier pile lagging wall with tiebacks to facilitate the construction of a permanent wall. They are [...]
ASFE has been a fixture in the geoprofession since its inception in 1969.

Congratulations to Crux Subsurface, Inc. on winning the Deep Foundation Institute's (DFI) 2014 Outstanding Project Award (OPA) and the 2014 C. William Bermingham Innovation Award for their Sunrise Powerlink Project in California. The project involved the installation of over 3,700 micropiles for the foundations of new steel lattice towers for a 117 mile transmission line running from Imperial Valley to San Diego. All of the micopiles were installed using rigs and equipment mobilized by [...]
Geotechnical work has commenced for a project involving reconstructing the Historic Columbia River Highway in Hood River County as a segment of Oregon's Historic Highway State Trail. The geotechnical scope consists of 48 test pits, 58 boreholes, and constructing 4,000 linear feet of temporary access roads. [Source: Hood River News. Image: Hood River
Torrential rain in the World Cup city of Natal caused a landslide right around the time that the USA defeated Ghana. According to the Landslide Blog, the landslide destroyed 50 homes but there were no lives lost. A You-Tube Video showing the landslide as seen from a small UAV shows the devestation, and interestingly shows a storm drain that could have played a role in the failure, perhaps becoming overwhelmed after the 50 hours of rain that fell on Natal.

Hawthorne, NJ (May 28, 2014): DFI announces the formation of a new, 16th technical committee focusing on site investigation for deep foundation design and construction.
The Subsurface Characterization for Deep Foundations Committee was formed to increase awareness of the importance of complete and competent site investigation in deep foundation practices. The specific goals of the committee will be defined by the committee members, however, initially the committee will discuss and define [...]
I know this video made the rounds by email and on Geoengineer a while back, but I haven't posted it here. It shows a novel way of installing piles in softer soil. Those guys have some nice rhythm! Happy Friday.

A massive mudslide approximately 1 mile by 3 miles by 250 feet deep has occured in Western Colorado over the Memorial Day weekend. There are reports that 3 men from the nearby Collbran/Mesa area are missing. According to the Forbes article, the estimates of the size would make it three times the size of the catastrophic Oso landslide in Washington. [Source: Forbes via @CanGeotechJournal.

This is a different perspective on landslides than what I usually blog about on GeoPrac. This banking and insurance website blog post discusses what should and shouldn't be covered on a car owner's insurance policy. Several cars parked along the road were damaged after a retaining wall / slope failure in Baltimore last month. [Source: Read the blog post at Bankrate, Inc.. Image: CBS
