AMS makes samplers ranging from hand augers to sonic drill rigs and direct push rigs for geotechnical and environmental sampling. This video gives an overview of the origins of their company in 1942 and their various product offerings.
I stumbled across this video for the geotechnical engineering centrifuge at Rensselaer Polytechnic Institute. Centrifuge testing is a popular way to economically test models at much higher loads and pressures than you would normally be able to in the laboratory. The goal is to more accurately represent the real world conditions. Click through for the video.
A 200-ft plus diameter sinkhole, about 50-ft deep opened up about 75 miles southwest of Lubbock, Texas, near Denver City on Monday, 7/27/2009 at 11pm. Check out the video below which is basically some aerial still photos. Credit to Geology.com. (Image from KCBD Video) […]
From the USGS Newsroom:
USGS scientist Ken Hudnut fills us in on how science created the theoretical magnitude 7.8 earthquake behind the Great Southern California ShakeOut—the largest earthquake preparedness drill in U.S. history, coming Nov. 13—and what such an earthquake would do to downtown Los Angeles.
Seems like they did it right wiith this study. They had multiple teams independenlty come up with the ground shaking model, then had different structural engineers who are experts in seismic design of large buildings review the tall buildings in the L.A. area for the design earthquake. They say that buildings would likely come down in the 7.8 magnitude event. Click through to watch the video interview from the USGS.
