As reported by the San Jose Mercury News:
The Bay Area has a nearly three-in-four chance of experiencing a potentially deadly earthquake in the next 30 years, scientists reported Tuesday in a long-awaited update of statewide earthquake probabilities that provides the most precise look yet into our foreboding seismic future.
The newly revised estimates show a 72 percent chance that a magnitude-6.7 or larger quake — almost the size of the 1989 Loma Prieta temblor — will strike the Bay Area before the year 2044. The odds of a much larger magnitude-7 quake are 50-50.
“The San Francisco Bay Area should live every day like it is the day of The Big One,” said U.S. Geological Survey scientist Ned Field, lead author of the eight-year-long analysis, called the “Third Uniform California Earthquake Rupture Forecast.”
