This page shows a simulation of the 100000 kt nuclear bomb (100000 kt) detonated over Berlin, Germany. The map displays the estimated fireball, the zones of heavy, moderate and light blast damage, thermal radiation and ionizing radiation.

100 megatons was the design yield of the Soviet AN602 — the Tsar Bomba — before its final stage was throttled back to 50 for the 1961 test. No weapon of this size was ever deployed: the bomb weighed 27 tonnes, no missile could lift it, and the arms race moved towards many smaller warheads instead. This scenario is therefore a physical ceiling, not a military one. The rings are enormous: a fireball about 12 km across, total destruction (20 psi) to roughly 13 km, collapse of houses (5 psi) to about 32 km, third-degree burns on exposed skin to about 75 km in clear weather, and broken windows (1 psi) out to about 100 km.
What that means in Berlin
Centred on Mitte, the 13 km zone of total destruction covers nearly the whole city inside its limits — Charlottenburg, Spandau's edge, Kreuzberg, Neukölln, Marzahn, Pankow. The 32 km collapse ring reaches Potsdam, BER airport, Oranienburg, Bernau and Königs Wusterhausen — about 4.5 million people. Burns to 75 km extend to Brandenburg an der Havel, Eberswalde, Neuruppin, Lübben and Jüterbog; the 100 km ring of broken windows reaches Frankfurt (Oder), Wittenberg's approaches and Prenzlau. The flat, sandy plain and the lakes offer no protection. The 800-kiloton scenario shows a realistic single warhead.
