Johnston Island is in the northern hemisphere, as were all of the planned Operation Fishbowl nuclear detonation locations. It was known from previous high altitude tests, as well as from theoretical work done in the late 1950s, that high-altitude nuclear tests produce a number of unique geophysical phenomena at the opposite end of the magnetic ...
The Starfish test was originally planned as the second in the Fishbowl series, but the first launch was lost by the radar tracking equipment and had to be destroyed in flight. [4]: 247 The initial Starfish launch attempt on June 20 was also aborted in flight, this time due to failure of the Thor launch vehicle. The Thor missile flew a normal ...

The Cold War ended in 1991, but the looming threat of nuclear attack lives on with more than 14,900 nuclear weapons wielded by nine nations.. A terrorist-caused nuclear detonation is one of 15 ...
This article contains a list of nuclear weapon explosion sites used across the world. It includes nuclear test sites, nuclear combat sites, launch sites for rockets forming part of a nuclear test, and peaceful nuclear test (PNE) sites.
The specific characteristics of a particular nuclear EMP event vary according to a number of factors, the most important of which is the altitude of the detonation. The term "electromagnetic pulse" generally excludes optical (infrared, visible, ultraviolet) and ionizing (such as X-ray and gamma radiation) ranges.
It involved detonation of a 5.3 kiloton device at a depth of 2,700 feet (820 m). [3] The second test, known as the Sterling Event, took place on December 3, 1966 and involved detonation of a 380-ton device suspended in the cavity left by the previous test. [ 2 ]
