Unfortunately the PEOPLE living here in L.A. are at an all-time LOW with regards to earthquake preparation. The fact that we have gone 21 years since the Northridge quake has lulled everyone into false security. Very few people have enough water to last more than a couple of days.
Really? Is the glass half empty or half full? While I certainly don't want to claim that SoCal if "fully prepared," there are hopeful signs - the development of CERT, the development of regular EQ awareness events,some enhancement in building codes (although this is far from perfect), and the development and distribution of hazard maps. The mayor is pushing hard for infrastructure improvements which seems like a no-brainer.
EQ preps are interesting. You are getting ready for an event which may never occur in your lifetime,and yet you stockpile stuff and adopt a series of habits which will be useful if it starts shaking. And then you get on with life
Those of us on the Pacific Plate are moving past the NA plate about as fast as fingernails grow,and yes,stress is increasing. When and where this stress will release is anybody's guess. A great deal of the time it occurs on a fault not previously recognized (like Northridge)
One last encouraging note. When Northridge struck, I was on San Miguel Island(the westernmost of the Channel Islands). When Loma Prieta struck, I was again on San Miguel island. That's a 100%, perfect correlation. You will be happy to know I have no plans to visit San Miguel Island in the future,and, if I do go there, I will announce it in advance. That's the least I can do....
