Before the sun rose on April 18, 1906, an earthquake shook the City of San Francisco. It leveled buildings and, even worse, caused devastating fires that raged for days. Those of us who live near one or two or three fault lines try not to think too much about the probablity of a repeat performance. The local government, on the other hand, has lots of good advice about stockpiling water and stashing away food, enough to carry us through the 72 hours we can expect to wait for help to arrive post-disaster. It’s useful information for folks outside of California, too, like my sister who lives smack in the middle of Tornado Alley or my parents, who are heading off soon to a peaceful retirement on Pine Island…off the Gulf Coast of Florida. Crazy family.
