Quote from blackjack007:
some of you know absolutely nothing about earthquakes or even about this one, and you're speculating? the japan quake happened 240 miles from tokyo. tokyo didn't fall into ruin because of the quake's distance, not because they possess some magical structural engineering process that only japanese have. had it happened 20 miles away, the city would have been obliterated, and i mean that literally not figuratively. any structures that withstood the shaking would have been burned in the ensuing fires. do you think their gas and water mains can withstand a 9.0 quake? please!
the destructive quakes that have happened in calif were always close to population centers which is why there was so much damage. furthermore, they were very shallow (10 mi deep versus 20 in japan).
