Explosion Danger Area CalculatorI found some interactive blast map calculators that were mildly entertaining to my inner-geek. You can choose from a selection of major international cites New York City is noticeably absentwind speed, wind direction and bomb yield. FAS, an organization endorsed by 69 Noble Laureates, was founded in by scientists who had worked on the Manhattan Project to develop the first atomic bomb. A main focus of the group is to reduce nuclear weapons. Clicking anywhere on the map will move the location of detonation to that point. The results are three concentric circles, which are not explained. You pick the bomb yield and four concentric circles show the overpressure created at four distances from the point of detonation. I had difficulty moving the point of detonation around the google map. You can find additional coordinates latitude and longitude for cities by clicking here. Kennedy School of Government. Nuclear Bomb Effects Computer — online retro edition — Wow, this is cool. During the Cold War you could purchase a circular slide rule from the U. John Walker has recreated this calculator online in a unique way: for blast affects you input the variables of bomb yield and distance, and for radiation affects you input time and dose rate. The output is an image of the original slide rule showing the results. Click here for the instructions. This entry was posted on June 16, at pm and is filed under PreparationSurvival.

Lots of variables to consider, but if we assume two different weapons yields and two different placements 1 KT atomic demolition or crude gun type homemade weapon, surface burst and KT cruise missile warhead sold to terrorist, light aircraft provides low airburst we can get the general picture for a terrorist nuclear attack. In either case, a single weapon will cause some fallout, but the lack of counterforce impacts would mean a robust tracking and public notification response. Now if the attack is from Russia with love, and hits the fairly well known bunkers with a 50MT bunker buster each, the whole middle seaboard will see fallout. Depending on the wind that day. I really want to know for how long with the radioactive fallout be harmful — e. This may be of interest:. Ten kiloton — Radioactive fallout contaminates a km area, prohibiting residence for years. Fires and lethal radiation would be felt up to 1 mile from ground zero. Radiation fallout from debris clouds will be seen, depending on wind variables, for several miles from ground zero.

Explosion Yield Calculations
HYDESim maps overpressure radii generated by a ground-level detonation; these radii are an indicator of structural damage to buildings. No other effects, such as thermal damage or fallout levels, are included in this tool. Note that the displayed rings are "idealized"; that is, no account is taken of terrain, urban density, ground type, weather conditions, and so on. Controls center detonation in view center view on detonation permalink. Complete destruction of reinforced concrete structures, such as skyscrapers, will occur within this ring. Between 7 psi and 15 psi, there will be severe to total damage to these types of structures. Severe damage to complete destruction of reinforced concrete structures, such as skyscrapers, will occur within this ring. Complete destruction of ordinary houses, and moderate to severe damage to reinforced concrete structures, will occur within this ring. Severe damage to ordinary houses, and light to moderate damage to reinforced concrete structures, will occur within this ring. Light damage to all structures, and light to moderate damage to ordinary houses, will occur within this ring. Most glass surfaces, such as windows, will shatter within this ring, some with enough force to cause injury.

TNT is an explosive block that can be primed to generate an explosion. Nine TNT blocks occur naturally in each desert temple trap. Two TNT blocks flank a trapped chest in one secret woodland mansion room. TNT can be broken instantly with any toolor without a tool. However, primed TNT cannot be broken, as it is an entity. TNT can be found in 8. In Bedrock Editionthey can be found in TNT drops itself when broken with the correct tool if any is assigned. Refer to the Obtaining section for more info. Once activated, TNT turns into an entity, which means it is now affected by gravity. Primed TNT's texture blinks, with its texture alternating between its standard texture and a pure white texture. The texture blinks at a rate of 2 times per second. Once spawned, primed TNT is given a vertical velocity of 0. If it does not collide with another block, it travels 0. When the countdown timer expires, the TNT explodes. When unsupported, it falls for roughly 77 blocks before exploding. The explosion has an explosive force of 4. When primed TNT is directed toward a nether portalit simply passes through the portal blocks and not travel into the Nether. In Java Editionprimed TNT explodes immediately if summoned by a command without specifying the fuse time, because said time defaults to zero. If the TNT is primed atop any sort of fence post that is two blocks high or larger, it falls through the fence block on which it was activated, and stops on the next lower one. Its detonation damages only the fence block it was "stuck" in.
The values in the output boxes above now are for the central excavation pit crater, the spall crater is indicated here:. The Target:. An asteroid. The Explosive:. TNT radius cm ft meters. The Impactor:. Impactor Diameter or choose crater diameter below : cm meters feet kilometers. Plot PiV type below versus Pi2 for a range of impactors from: to: cm meters feet kilometers. So the Mass is: grams kgrams Tons pounds Kilotons. The Excavation Crater Size is:. Show me the Profile:. Crater Diameter for impacts, can input this and solve for impactor meters cm kilometers feet. Rim Diameter meters cm kilometers feet. Lip Height meters cm kilometers feet. Formation Time msec sec minutes. Melt Mass grams kgrams Tons pounds Kilotons. Vapor Mass grams kgrams Tons pounds Kilotons. And it is in the Cratering Regime. For this brittle material and defined gravity, craters are spall craters if their excavation diameter as given above is less than meters. So the Final Crater is a Spall Crater, Its Size is: The values in the output boxes above now are for the central excavation pit crater, the spall crater is indicated here:. An example spall crater with a central pit:.
