Video: Low-Tech Pile Driving Option

GeoPrac.net sponsor Novo Tech Software recently released this video that gives an overview of their company and all of their various geotechnical software products.  Very impressive, check it out!

The USGS has a documentary on landslide video on landslide danger in the San Francisco Bay area entitled “Riding the Storm”. I think the target audience is more general than geologist or engineer, but it is still interesting. The bullet points from the USGS site:

• A catastrophic 1982 rainstorm triggered 18,000 landslides in the Bay Area, claiming 25 lives and causing $66 million in property damage
• The combination of steep slopes, weak rocks, and intense winter storms make Bay Area uplands an ideal setting for landslides
• Landslides include both swift, potentially deadly debris flows and slower, but destructive deepseated slides
• Learn what USGS scientists have discovered about landslide dynamics and which slopes are most susceptible to sliding
• Hear the devastating stories of Bay Area residents affected by landslides and learn to recognize the danger signs

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.
