SURVIVENuke Map — Nuclear Blast Radius on Your City
See the scale of a nuclear detonation on a place you know. This nuke map and blast simulator lets you enter any address, pick a weapon, and maps the nuclear bomb's blast radius and damage zones on your real streets. An educational tool — not a threat assessment.
This is an educational simulation, not a threat assessment. Figures are simplified approximations from public physics (Glasstone & Dolan, 1977) and vary enormously with real conditions. This tool exists to make the scale of nuclear weapons tangible — and to underline why their abolition matters. It does not predict targets, model any real attack, or constitute emergency guidance. Your address is never stored.
How the blast radius is calculated
This nuclear blast simulator estimates each damage-zone radius from publicly available scaling laws in The Effects of Nuclear Weapons (Glasstone & Dolan, 1977). Overpressure follows the cube-root scaling law; thermal and fireball radii follow their respective power laws. Real effects vary enormously with weapon design, height of burst, weather, and terrain — treat these blast-radius figures as order-of-magnitude estimates. Casualty counts are intentionally not shown.
Frequently asked questions
How far does a nuclear blast reach?
It depends entirely on the weapon's yield. A 15-kiloton bomb (Hiroshima) causes severe damage within about 2 km; a 1-megaton warhead can shatter windows more than 10 km away. Enter an address above and pick a yield to see the specific radii for your location.
How accurate are these numbers?
They are educational approximations from the publicly available scaling laws in The Effects of Nuclear Weapons (Glasstone & Dolan, 1977). Real effects vary enormously with weapon design, height of burst, weather, and terrain — treat them as order-of-magnitude estimates, not predictions.
What's the difference between an air burst and a surface burst?
An air burst detonates above the ground and maximizes blast damage over a wide area. A surface burst couples more energy into the ground — slightly smaller blast and thermal reach, but far more local radioactive fallout.
Is this tool dangerous, or could it be misused?
No. A nuclear-effects calculator is not a nuclear weapon. Every formula here comes from unclassified, decades-old public physics — there is no secret information involved. The tool exists to make the scale of these weapons tangible, which is exactly why organizations working toward disarmament build tools like it.
Do you store my address?
No. Your address is used only in your browser to place the map, and is never stored on our servers. Shared links carry only a coarse city/area label — never your exact street address.
