Choose a city, choose a nuke and see the fallout.

A little boy more then takes care of Camden.

It's always comforting to think the atmosphere will protect us from space-borne threats but it's a false comfort. Most Meteors enter the atmosphere at about 18 miles per second. They are essentially in, through and hit in under 2 seconds. Comets can have some phenomenal speeds, upwards of 40 miles per second. That's essentially a "blink" done. The resulting atmospheric pressure wave from a 1 mile in diameter comet will probably end life for the hemisphere it hits. The energies are astounding.

No biggie - we won't see it coming and won't know we're gone.

Just a little..

Asteroid/comet impact... not if, but when... unless we can figure out out to detect and stop them.

I am working currently on a consequence managment planning project of a IND in 5 of the major cities in my territory. The IND is modeled to a 15kt weapon carried in a light cargo truck or van. I can say that this website has it almost spot on, and the Version 2 page is even better. Ths only thing I dont like is the generic fallout calculations and model, that do not take into consideration current weather patterns or conditions. But what are you going to do in a simple web page.

 

That asteroid is bugging the hell out of me... i cant replicate it. I would love to see the parameters they used to spec the materials/size.

According to my calcs, a 168gr bullet traveling at 18miles per second (95,040 fps) has 3,368,802.46 ft/lbs of energy behind it on impact. I don't want to think about what a few tons of mass would do at those velocities.
