What happens if a city disappears

What New Oreleans could look like after Katrina

DEVASTATING DAMAGE EXPECTED

MOST OF THE AREA WILL BE UNINHABITABLE FOR WEEKS...PERHAPS LONGER. AT LEAST ONE HALF OF WELL CONSTRUCTED HOMES WILL HAVE ROOF AND WALL FAILURE. ALL GABLED ROOFS WILL FAIL...LEAVING THOSE HOMES SEVERELY DAMAGED OR DESTROYED.

THE MAJORITY OF INDUSTRIAL BUILDINGS WILL BECOME NON FUNCTIONAL. PARTIAL TO COMPLETE WALL AND ROOF FAILURE IS EXPECTED. ALL WOOD FRAMED LOW RISING APARTMENT BUILDINGS WILL BE DESTROYED. CONCRETE BLOCK LOW RISE APARTMENTS WILL SUSTAIN MAJOR DAMAGE...INCLUDING SOME WALL AND ROOF FAILURE.

HIGH RISE OFFICE AND APARTMENT BUILDINGS WILL SWAY DANGEROUSLY...A FEW TO THE POINT OF TOTAL COLLAPSE. ALL WINDOWS WILL BLOW OUT.

AIRBORNE DEBRIS WILL BE WIDESPREAD...AND MAY INCLUDE HEAVY ITEMS SUCH AS HOUSEHOLD APPLIANCES AND EVEN LIGHT VEHICLES. SPORT UTILITY VEHICLES AND LIGHT TRUCKS WILL BE MOVED. THE BLOWN DEBRIS WILL CREATE ADDITIONAL DESTRUCTION. PERSONS...PETS...AND LIVESTOCK EXPOSED TO THE WINDS WILL FACE CERTAIN DEATH IF STRUCK.

POWER OUTAGES WILL LAST FOR WEEKS...AS MOST POWER POLES WILL BE DOWN AND TRANSFORMERS DESTROYED. WATER SHORTAGES WILL MAKE HUMAN SUFFERING INCREDIBLE BY MODERN STANDARDS.

THE VAST MAJORITY OF NATIVE TREES WILL BE SNAPPED OR UPROOTED. ONLY THE HEARTIEST WILL REMAIN STANDING...BUT BE TOTALLY DEFOLIATED. FEW CROPS WILL REMAIN. LIVESTOCK LEFT EXPOSED TO THE WINDS WILL BE KILLED.

AN INLAND HURRICANE WIND WATCH IS ISSUED WHEN SUSTAINED WINDS NEAR HURRICANE FORCE...OR FREQUENT GUSTS AT OR ABOVE HURRICANE FORCE...ARE POSSIBLE WITHIN THE NEXT 24 TO 36 HOURS.


The next closest thing to this is a nuclear explosion

A TEN-KILOTON BOMB DETONATED AT GROUND LEVEL

If a bomb in the 10- to 20-kiloton range (the likeliest terrorist bomb) were to be exploded near ground level or in a ship in the harbour, the areas of blast, heat, and burn damage would be much smaller, perhaps reaching out to only one-tenth of the distances estimated for the one-megaton air-burst. The numbers of immediately killed and severely injured people would be counted in thousands, not hundreds of thousands.

Exploded on land, the bomb would vaporize all people and buildings in the immediate vicinity, and make a crater that might be as much as one hundred metres in diameter. If in the harbour, there would be a crater in the harbour floor and a tidal wave. The outstanding feature would be a radioactive downpour because much of the water in the harbour would be made radioactive and thrown high into the air as fine and coarse spray.

The explosion at ground level of this type of bomb would probably not cause a firestorm, so rescue operations for the injured might have some degree of success.

In either case, radioactive fallout would be serious, and might make the city, and an area of countryside stretching tens of kilometres downwind, uninhabitable for weeks or years. There would be a number of deaths from radiation sickness, for which there is really no effective medical treatment. The total amount of radioactivity might be comparable with the Chernobyl disaster, more or less depending on many circumstances.

A couple of months ago, Rick Santorum wanted to bar the National Weather Service from sharing some of it's data with the public.

Let's see: talking points for tommorrow.

1) Will Bush give up his vacation as a major American city is wiped off the map? We hope that this isn't the case, but if it is, will Bush finally act like a leader or hide again.

2) Why is the Lousiana National Guard as well as their first responders in the Marines, Army, Navy and Air Force reserve not home to help save their city?

3) Why did the Bush administration repeatedly cut funding for the Corps of Engineers district since 2001, despite being warned that this was one of the most likely disaster to hit the US, after a terrorist attack in New York.

Jen noted that most of the poor will be jammed into the Superdome, which will is expected to lose power. So people will be jammed into a hot, crowded building. One can only hope that it can withstand the storm.

UPDATE: While the storm passed to the east of New Orleans, turning into a Category 4, the winds and damage is still catastrophic.

Also, CNN is reporting that the Superdome now has a gash in in it's roof and people can see daylight through it. And the worst winds have yet to arrive
