This page shows a simulation of the Topol (SS-25) (currently in Russian arsenal) (800 kt) nuclear bomb (800 kt) detonated over Honolulu, HI, USA. The map displays the estimated fireball, the zones of heavy, moderate and light blast damage, thermal radiation and ionizing radiation. Click «What does that mean?» for a detailed legend, or run your own detonation on the main page.
The 800-kiloton warhead of the Topol (SS-25) is the kind of weapon a strategic missile actually carries today — about 50 Hiroshimas, delivered in roughly 30 minutes. On this map it is an airburst, the height chosen to maximise the area of heavy blast damage. The fireball is about 1.8 km across; total destruction (20 psi) reaches roughly 2.6 km, residential collapse (5 psi) about 6.5 km, third-degree burns on exposed skin about 11.5 km, and broken windows with flying-glass injuries (1 psi) about 20 km.
What that means in Honolulu
Centred on downtown Honolulu, the 2.6 km zone of total destruction covers the business district, Chinatown, Iolani Palace and the harbour. The 6.5 km collapse ring reaches Waikiki's hotels, Ala Moana, Punchbowl crater, the University of Hawaii at Manoa and the airport's eastern runways; burns to 11.5 km extend to Diamond Head, Pearl Harbor's entrance and Hickam Air Force Base, and up the valleys to the Koolau ridge. The 20 km ring of broken windows covers Pearl City, Aiea, Hawaii Kai and crosses the ridge towards Kaneohe.
About a million people live on Oahu and the great majority of them inside the outer ring. Honolulu is also the one scenario here where terrain really matters: the steep Koolau mountains shield the windward side, and the ridges between the valleys would cast long thermal shadows — switch the terrain-shadow option on to see them. Honolulu has been a strategic target since 1941 because of Pearl Harbor; the 100-megaton version would reach every corner of the island.
