It’s the elevators that worry earthquake engineering expert Keith Porter the most.
Scientists say a massive quake could strike the San Francisco Bay Area at any moment. And when it does, the city can expect to be slammed with a force equal to hundreds of atomic bombs.
Porter said the shaking will quickly cut off power in many areas. That means unsuspecting people will be trapped between floors in elevators without backup power. At peak commute times, the number of those trapped could be in the thousands.
