ROBERTO:
        Curious thing happened about 10 years ago. Someone checking records
made the discovery that Parkfield, located right on the SA fault, has since
1857 had a 6.0 shaker every 21-22 years. That why there's been this huge
buildup of research projects there for the last seven years, with people coming
from all over the world (including the USSR) to see it. Only once, 1934, has it
been off when it came 10 years early. The current one is two years overdue. As
we saw when we there, however, the ground is constantly moving.
