Video: Plotting Strike & Dip Symbols in Google Earth using RockWorks

A colleague of mine sent me an amazing video of a culvert failure and subsequent road collapse in Freeport Maine during a storm. The culvert was unable to accommodate the high volume of water, and it was backing up behind the roadway embankment like a dam, and spilling out onto the roadway. In a span of about 3 minutes, the entire section of road collapsed and was washed downstream. I don’t know the exact date the video was taken, but it appears to be in August of 2008.

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
