text:  When that earthquake occurred, it was on the day of the full moon, January 9th, 1857, and the ground moved 30 feet. That's why I say I'd like not to be straddling the fault line. 30 feet? 30 feet. There was a round sheep corral that was 30 feet in diameter, and after the earthquake, it was the shape of the letter S. Wow. And it was slightly larger than the 1906 earthquake, probably an 8.4.
