About a week ago, I and about 14 other people experienced
two earthquakes in a row; and then another ~15 people experienced them about 10
minutes later, and it continued that way all afternoon. Micro-aftershocks? No, it was the new Earthquake exhibit at San
Francisco’s
California Academy of Sciences in Golden Gate Park, where they have
a “shake house” that first simulates the 1989 Loma Prieta earthquake and then
simulates the 1906 San Francisco quake.
That was a fascinating experience for me, because when I felt the real
1989 quake, I was outdoors, which is a very different experience; and when I
went through the 1971 Sylmar earthquake, I was a little boy in my bed, and was
more bounced around than shaken.
Standing on the floor and having the walls shake and the floor rock and
shift certainly does feel different.
While experiencing these simulations, a few things occurred
to me. First, the books didn’t fall off
the shelves, the picture didn't crash down to the ground, the fishbowl did not
slide off the shelf, the cabinet doors did not swing open, and the glasses did
not break all over the floor. That was
because this was an exhibit rather than a real home and everything was fastened;
which is a great example of why in your real home, it’s a good idea to have
everything fastened! Second, it sure is
useful for the kitchen to have a hand-rail with capacity for ~15 people to hold
on to it, and to have advance warning; but of course those exhibit features
presumably will NOT make it into your real home. And lastly, and this will be more meaningful
to actual San Franciscans, the view out the fake window from this shake house
of the famous “Painted Ladies” Victorian houses seems to put the location of
this hypothetical house right in the middle of Alamo Square Park...but we’ll
let that one slide.
One more thing that occurred to me is that experiencing the
feel of these quakes is good preparation for the real thing. It is hard to respond effectively to the
unfamiliar; easier if you have already gone over in your mind the sounds and
sensations that you will probably experience.
Amanda Ripley, in her truly excellent and gripping book “The Unthinkable,”
describes various real disasters and discusses how the simple act of knowing
what you will do before the unexpected occurs can make a crucial difference in
the outcome. I imagine that not just
knowing what you will do, but also knowing what you will likely be
experiencing, will help save those extra few seconds that are better spent
responding than freezing like a deer in the headlights.
Other nice aspects of this exhibit were the planetarium show
in which you can see cool simulations of the continents drifting, fly through
the San Andreas Fault, and be part of a very realistic CGI simulation of San
Francisco’s Market Street in the early morning as the 1906 quake was hitting;
and also the real live ostrich chicks running around in the pen as an example
of the speciation that has occurred due to tectonic plate movement.
I’m glad I finally got the chance to attend this
Earthquake exhibit, especially since one of my recent earthquake preparedness
talks was at the SF Main Library in partnership with the California Academy of
Sciences itself, so I was part of their lecture program associated with this
exhibit. Presumably I was not as cute as
the ostrich chicks but I’m glad to have been able to contribute a bit to the
effort!
