Video: California residents prepare for 'the Big One'

All Californians are aware that one day "the Big One" – a massive earthquake – will hit the San Francisco Bay area. According to experts, there is a 90 percent probability that it will happen within the next three decades. In 1989, many Californians thought the dreaded moment had arrived when a 6.9-magnitude quake rocked the bay, killing 67 people and injuring thousands. That quake cost billions of dollars in damages, one of the most costly US natural disasters.
