Yep, Radsafe has had discussions about quakes, tsunamis, planes
flying into reactors etc.
What should we have done earlier????
Many of Japan's reactors are right along the ocean coastline.
With knowledge of the quakes,
tsunamis. etc. there, perhaps building a 20 to 40 foot tall sea wall along
the coast (near each reactor)
should be done. Large magnitude 8.0 or so earthquakes appear to occur in
Japan about every 25
years or so. I could do a PhD on Japan quakes, tsunamis, etc. and still
come up with a similar
number. The earthquake associated with Fukushima was in the vicinity of
magnitude 9.0, which
probably doesn't happen once in 100 years. Compare this with a reactor
lifetime of 40 to 60
years... I expect the rest of Japan's reactors should remain in service
until the end of their lifetime.
Magnitude 9.0 events are not all that common... Chile and Alaska in
a recent Chilean event, the 2 to 3 earthquakes in Indonesia occuring around
2000 - 2010,
the recent Fukushima-associated earthquake....
A gentleman with a pretty profound knowledge of Japanese
earthquakes and earthquakes
in general is Dr. Hiroo Kanamori of Caltech (California USA). I don't
know if Dr. Kanamori still
gives public seminars/lectures, but maybe some southern California HP
chapter could invite him to
one of their meetings to give a talk.
Fukushima reactor engineering was pretty darned good, considering
the hazard involved.
Most US nuclear plants have NO tsunami risk. Is San Onofre the
Right now, for the next 6 weeks or so is earthquake season (global),
and the main question is
where??? Location, location, location....!!!!! So, if you notice your
cats, dogs, horses,
cows, pigs, etc. acting strangely, maybe there is a reason. Previously,
there have been reports of
strange animal behavior in China prior to very large earthquakes.
Bolt's book on Earthquakes is pretty good for a public audience,
with Stacey for general
geophysics and Aki and Richards for Graduate level Seismology (complete
source terms and Green's functions). Peruse the last book at your own
