Missouri S&T (known as UM Rolla a while back) has a number of courses that are available through their YouTube channel. One such course is their GeoEng 341 course, Engineering Geology and Geotechnics taught by Dr. David Rogers. You can watch the entire series of 15 lectures totaling over 32 hours on You-Tube! Check out the first lecture below.

Pucker-worthy Debris Flow Video
I saw this video a few weeks back on The Landslide Blog, and it’s also been posted on GeoEngineer.org. It’s well worth the watch. It’s one of the scariest debris flow videos I’ve seen. Some […]

Video: Alaskan Way Viaduct Earthquake Simulation
Seattle’s Alaskan Way Viaduct and Seawall Replacement Project is a political lightning rod, but this amazing simulation video released by WSDOT underscores what COULD happen if a significant earthquake struck the Seattle Downtown Waterfront area.

What Would a Large Earthquake Do to Downtown L.A.?
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.

There are so many projects and engineers who could benefit from listening to Rogers. There is a science to it and identifiers that can tell the engineer how the soil has responded over time.
