Earthquakes and all that is 'thought' to be known
Seismologists are predicting a horrific 700 year earthquake event that is due in the Pacific Northwest (PNW). As was learned by the Chilean earthquake, our earthquake construction standards aren't adequate. We have designed our structures for a 20 second shake, not like the 2 - 3 minute shake that destroyed buildings in Chile. The Chilean engineers used the same standards as the PNW employs.
