There is bound to be a major earthquake in San Francisco sooner or later and chances are that it will occur in the next few decades. In 1980 a federal report declared the likelihood of a major earthquake hitting California within the next 30 years was ‘well in excess of 50 percent’ and yet the Big One has yet to strike. While on holiday in California, most tourists are unlikely to give the idea of an earthquake happening a second thought. Yet California has more than 300 faults running beneath its surface, so while you're there, it's possible that you could feel the earth move, even if you are so busy doing other things that you probably won't! Nevertheless, the Big One is coming — there’s no doubt about it.
