There is a nice article on slow moving landslides at Nature.com. They discuss the use of InSAR technology and point out how a number of landslides in the news over the past several years have had at least some movement before a catastrophic event. To me, the interesting part is just how a topic of interest to geoprofessionals is covered by scientists who perhaps aren’t experts in these areas. They also mention some of the more infamous slow moving landslides that are currently being researched. It’s worth a quick scan.
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
