USGS Landslide Documentary Video
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

Video Tour of NY Subway Mega-Projects
The New York MTA is in the midst of a “golden era” of tunneling for the New York subway. Three separate mega-projects are currently underway totaling some $15 Billion: The Second Avenue Subway, The East Side Access Project (which features the new Grand Central Terminal), and The Number 7 Subway Line Extension Project. The short video below was published by the NY Post and included in an AP Article. It is tantalizingly short, but gives a great perspective on what the underground construction project at Grand Central looks like and a sense of the scale…the amazing huge caverns being constructed. The article says that from underneath Grand Central Terminal alone, the construction crews have removed enough material to cover Central Park almost a foot deep!
