How do you evacuate New York City in a few hours?
Hillary Clinton striptease?
Elevators.
Well if we can develop a very good system we could have several weeks notice hopefully.
A biggie sized enema?
Nuke it?
You're soon going to pay to find out.
As soon as the Committee for Expaining Boll weevil Constipation has issued it's report, that is.
You don't. Likewise Boston, Philadelphia, Norfolk, Charleston ...
Vertically. You'd be safe on an upper floor of a well-constructed building as opposed to a basement studio or on the street.
I would leave now and avoid the rush.
You could not evacuate, but you don't need to. You can move tens of thousands of people to higher ground- get away from the shore and several stories high and you'd have a much better chance than down by the docks, in a subway, or just on the street. Lower floors would take damage, mostly broken glass, but it would take a much bigger wave than 30 feet to knock down a steel-framed building.
We used to have a Civil Defense program with coordinators and shelters and volunteers and training and supplies, for nuclear war, but it was also useful for natural disasters like tsunamis, floods, and the like. We gave it up long ago (a treaty with the Soviets I think).
If you had 5,000 CD trained people, and each coralled a thousand people into safer zones, that's lots of people off the street. Perfect, no, but would it have saved lots of lives in India? You bet.
I don't think New York City would be too seriously affected due to its geographical position. Manhattan island sits north of the ocean in the middle of the Hudson, and the Long Island part of it would be buffered by the barrier islands.
"How do you evacuate New York City in a few hours?"
You don't. The infrastructure won't support that amount of traffic. Also, the resultant panic would cause an unbelieveable number of fatalities.
a NYC evacuation in a few hours time is truly a Nightmare scenario.
