On Tuesday, Mission San Jose south of San Francisco commemorated the Hayward fault earthquake of 140 years ago that killed 30 people and devastated the region -- a reminder of the need to be prepared, according to the U.S. Geological Survey. Calling the Hayward fault a "tectonic time bomb," the USGS predicts a magnitude 6.7 earthquake will happen again in the next 30 years.
