True, but being hit by a 767 must be equal to at least a medium size earthquake.
Second, the Marina District was built upon haphazard rubble tossed from the 1906 earthquake without any forethought to its suitability as substructure.
Dollars and donuts.
More like bagels and donuts. You can't compare any kind of landfill to solid bedrock, which is what New York skyscrapers were traditionally built on, as I understand it.
“True, but being hit by a 767 must be equal to at least a medium size earthquake.”
Again, bagels and donuts as you say.
I lived through both the Northridge earthquake AND the Loma Prieta earthquake. In both areas. Less than 10 miles from the epicenters in both cases. Can I pick the time to move, or what?
A blow above ground cannot be compared to a seismic event, totally different in the yield of destruction. The folks in the WTC towers got the worst of it, BUT it was limited to the buildings directly involved. (Yes, I know about the damage to buildings on the periphery.)
