1906 revisited?

It's only April 12th today, in six days it will be the 18. Do you remember what happened on 18 April 1906? The death, destruction, and mayhem that an earthquake measuring 7.9 on the Richter that almost demolished San Francisco. The terrifying rumble of an earthquake shattered the early morning silence of April 18 at 5:15 AM. The quake lasted only a minute but caused the worst natural disaster in the nation's history. Modern analysis estimates it registered 8.25 on the Richter scale (By comparison, the quake that hit San Francisco on October 17, 1989 registered 6.7). The greatest destruction came from the fires the quake ignited. These ravaged the city for three days before burning themselves out. The maelstrom destroyed 490 city blocks, a total of 25,000 buildings, made over 250,000 homeless and killed between 450 and 700. Damage estimates topped $350,000,000.
