[quote=Anonymous][quote=Anonymous]OP - how good are our building codes in DC earthquake-wise? When the Louisa earthquake hit, I was on the 8th floor downtown and it seemed like the building was going to fall down. [/quote] Not OP, but it will depend on the age and type of structure. Wood frame houses are naturally flexible and much better able to absorb EQ energy than older, brick structures (note the low casualties from the Northridge EQ, which occurred early in the morning, when California was still at home in bed). Modern office buildings typically incorporate engineering design that also absorbs a lot of the energy. [/quote]
