How destructive are today’s nuclear weapons?
The two nuclear weapons dropped on Hiroshima and Nagasaki, had an explosive yield of the equivalent of about 15 kilotons of dynamite and 20 kilotons of dynamite respectively. In modern nuclear arsenals, those devastating weapons are considered “low-yield.” Many of the modern nuclear weapons in Russian and U.S. nuclear weapons are thermonuclear weapons and have explosive yields of the equivalent at least 100 kilotons of dynamite - and some are much higher. One 100-kiloton nuclear weapon dropped on New York City could lead to roughly 583,160 fatalities, according to NukeMap.
