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
