October 17 was the 18th anniversary of the 6.9 magnitude Loma Prieta earthquake that struck the Bay area. But a recent story by the Bay Area’s local ABC affiliate, ABC7, chose to focus on another earthquake, a 1868 earthquake of about the same magnitude that occurred on the Hayward Fault. According to the USGS, the Hayward Fault has a return period of about 140-years and "It’s the most heavily urbanized fault in the U.S. and it’s just waiting to go off…" Next year will be the 140-th anniversary of the last earthquake on the Hayward Fault. At some point it has the potential to be a very bad earthquake there. More after the break. (Photo by sanbeiji)

The latest numbers according to AFP, Worldwide News Agency, is 71,000 dead, missing or buried and over 5 million homeless. There were many victims that were buried by landslides and rockfall. In the past few days 200 rescue workers have been buried by mudslides.
For more coverage on landslides related to the earthquake, I recommend Dave’s Landslide Blog. Geology.com also has very comprehensive coverage as well. (AFP Photo)
