Seneca Rocks Visitor's Center was experiencing geotechnical foundation problemsU.S. Forestry Service Saves Thousands with Use of TerraThane Geotechnical Foam by NCFI Polyurethanes at Seneca Rocks Discovery Center

MOUNT AIRY, NC— Seneca Rocks Discovery Center, the visitor's center for the eastern U.S.'s most popular rock-climbing destination located in Pendleton County, WV, had a growing problem common to concrete slab foundations: erosion of the soil beneath the slabs created voids that left areas of the center with uneven spots and settled anywhere from one-to three inches. That led to cracks in interior walls, uneven floors, and trip hazards for the thousands of visitors to the area's most popular scenic attraction. Seneca Rocks is a striking 900 ft peak that features over 375 mapped climbing routes varying in degree of difficulty from easier 5.0 to the hardest 5.13, and attracts climbers from around the world.

Retaining Wall failure at Ho Ching Yuen, Malaysia PDF Print E-mail

This retaining wall failure occurred in Kuala Lumpur, Malaysia in 2009. The failure was caught on video, albeit with a crappy camera phone. But it's well worth a look! Dave Petley of the Landslide Blog also tracked down an article on the original failure. It's the usual case of chicken or the egg. Did the water pipe failure cause the wall to fail, or did the wall fail and then cause the pipe to fail. Thanks to my colleague Bob Cummings of Saguaro Geoservices for sending this my way.

Sinkhole swallows Corvettes in Bowling Green, Kentucky

A 40 foot diameter sinkhole 30 feet deep opened up beneath the National Corvette Museum in Bowling Green, Kentucky, and swallowed 8 of the Corvettes on display. The museum's security company alerted the staff members that the motion sensors had gone off at about 5:40 am on February 12 in the 'SkyDome' portion of the museum, separate from the main building. The museum called in a structural engineer and some Karst sinkhole experts who used a remote controlled helicopter to get photos and video inside the sinkhole. See those videos below. The main museum will be open as usual tomorrow, but the SkyDome will be closed indefinitely. [Source: Image: National Corvette Museum via]

Feb. 7 Bertha update: Two factors contributed to tunnel stoppage PDF Print E-mail

Tuesday, 11 February 2014 00:40

WSDOT released an update on February 7 with some conclusions regarding the blockage that has stopped the Alaska Way Viaduct Tunnel Boring Machine, Bertha's progress since December 6. Now they don't think it was necessarily the well casing after all.

They cite two factors that contributed to the blockage. First, the cutterhead was clogged with material. You can see an cool short video of a worker unclogging the cutterhead. Not terribly dramatic, but still cool. The second factor was increased temperatures inside the equipment. STP discovered damage to a seal that protects the machine's main bearing. They are still determining how the repairs will be done.

If you want to follow the chronology of this issue, read below for summaries and links to previous updates from WSDOT. And Check out the videos too! [Source: WSDOT]

A giant boulder smashes through a barn of an Italian farmhouse

An Italian farmer and his family had an unbelievably close call with some house-sized boulders. You have to see the pictures to believe it. The boulders were dislodged during a landslide on January 21 in Northern Italy. One of the boulders smashed through the barn and courtyard of the farm and cut a swath through their vineyard before stopping near a boulder from some previous rockfall / landslide event. That older boulder is even bigger, about the same size as the entire farmhouse and big enough to be seen on Google Earth! See below or download the KMZ file.

Buildings are one with the rock in the Spanish town of Setenil De Las Bodegas

I had never heard of this town before seeing the post on Setenil de las Bodegas is a small town of about 3,000 people in the Spanish province of Cadiz. The town is built within the narrow gorge cut by the Rio Trejo. Some of the buildings in the town are built into caves and beneath rock overhangs making this a very dramatic, and exotic European town! [Source: More info at Image: La Pantera via Wikimedia]

John Bachner celebrated his 40th anniversary with ASFE: The Geoprofessional Business Association. He has worked tirelessly during that time to help geoprofessionals with the softer side of our business, including improving our writing, understanding contracts and liability, and improving business development skills. Bachner was honored at the fall 2013 ASFE/GBA meeting and presented with a mock ENR Magazine Cover by President Kurt R. Fraese, L.G. The reaction is priceless, but I wonder what was on the cover!

LIDAR Helps Locate New England Archaeological Sites PDF Print E-mail

LIDAR imagery from New England archaeological sites

One of the advantages of LIDAR topography data is the ability to "see through" vegetation so to speak. The light beams aren't actually seeing through physical objects, but because of the high density of LIDAR pixels, some of the beams in a vegetated area see through the canopy to the ground surface. The vegetation can then be screened out of the data using post-processing. This kind of "bare earth" imagery was recently used by archaeologists in New England to locate "lost" settlements that dated back to the 18th century.

Beer's secret ingredient: geology PDF Print E-mail

Similar in the way that people who know wine understand terroir, or how the earth and geology influences the nature of wine, Beer is influenced by the geology as well! This is a really neat little article that I saw mentioned in the AEG Insider. Did you know that areas with softer water typically produce lagers and darker ales, and those with harder, more mineral-rich water are more conducive to paler, hoppier ales? I'll drink to that. Cheers! [Source: Check out this important Beer article in EARTH Magazine! via AEG Insider]
