Your reactions on the spot. Do not go away and think about this, because had this been an actual emergency you would not have that luxury. This addresses your state of preparedness NOW. You can improve later, but the following are the scenarios: A. You live 8 miles from a sensitive military base or installation. There are no subsurface assets to speak of, so this selected target receives a 200kt airburst with no prior warning in the media. You are in your house and awake when it goes off, and because of brick construction you are not harmed by the gamma burst, and you're not looking directly out of the window. You have approximately 45 seconds before a heavily front-loaded shock wave hits your house, but due to dissipations of distance, the original 400mph surge is down to a survivable 95mph by the time it hits you. Still, the clock is ticking... You...? B. You are 55 miles from a major city. The prevailing winds are blowing in your favor, away from you, when without warning, a Chinese 600kt theater weapon explodes 3000' above the hypocenter downtown. The distance means the shockwave will be well dispersed and radiation is blowing away from you for the time being. Between you and the city at a range of 30 miles a major airport is hit by a 200kt groundburst meant to wipe out the runways and there is some heavy fallout but still the winds are blowing away from you. You're up and its a workday, but you havent left yet, though one of your kids is at the bus stop, but comes running back. C. Same as B, but its February and you've just had 2 feet of snow. At least the house is well stocked from the SuperBowl party leftovers and you knew the snow storm is coming. You... D. Its a Wednesday night just before 7p, and the President is to address the nation out of the blue, on a matter of "great national urgency" and it turns out to be some nuclear cliff walking with a belligerent nation which has just been read the riot act and warned that they better stand down or we're gonna toe the line with nukes. Some political deadline has been issued for 9am the next morning, if its even reached because things are getting Cuban-Missile-Crisis hairy. The military is under full mobilization and defcon one, the interstates are CLOSED and blocked by state troopers to facilitate military movements and that un spools just after the speech is given. Forget about going anywhere, the order is to close all supermarkets to avoid riots and prevent hoarding, with them to be re-opened under secure supervision for rationing under secure control after things go bad if it gets that far, or to keep chaos from taking over if things are ok but folks suspect it may not be over. The power is on, but the stock market is to be closed the next day and schools are shut down. You... E. In a fit of government efficiency, the EBS actually works and without any warning all programming goes off the air and the President suddenly appears or is heard, and announces that full scale nuke exchange is underway between us and the enemy of your choice, China or Russia. Typically ICBMS take 22 minutes but by the time they ID'd the problem and got the Prez to the basement, 7 minutes had passed and it takes a minute or two to process the information. You have less than 15 minutes, and you've just been given the major news and told to "take cover, under ground if possible" . Warning sirens are going off from the local fire department. Date, time and location of your choice, most likely for you in your scenario. You... Ready, set,.....SURVIVE!
