The shock wave was felt as far away as the Dikson settlement located 430 miles away, and windows shattered at a distance of 560 miles. Windows even shattered as far away as Norway and Finland due to atmospheric focusing of the shock wave. Despite being an air burst detonated 13,000 feet above ground, Tsar Bomba’s seismic magnitude was estimated at 5–5.25. Seismic sensors continued to register shockwaves even after a third revolution around the Earth.

Instead of some gay emplacement test they drop it out of a bomber as a fully weaponized build. Gotta like that. They gave the bomber crew an ifty-50 chance of surviving.
