Earthquakes, we know, we know

As you've probably heard, oh, a jillion times, today is the 100-year anniversary of the San Francisco earthquake. People tend to call it the 1906 earthquake, which seems a little obvious when we mention that it's the 100-year anniversary.
Speaking of obvious, the California Field Poll did a little study to gauge Californians' thoughts on natural disasters. Guess what tops the list? Righty-ho, earthquakes!
According to the poll, which was taken earlier this month, 59% of Californians fear earthquakes more than any other natural disaster; fires and mudslides are the runners-up. If this doesn't seem surprising, wait until we reveal the next stunning finding: 67% of Californians don't think earthquakes make our state any more dangerous to live than other parts of the country. We were all watching when hurricanes Katrina and Rita knocked the Gulf Coast halfway to oblivion.
Is a poll any use when it tells us what we all already know?
