A suggestion in a comment was that a reflection from a cloud could be seen. The creator said enabling people to visualize the effects in arbitrarily picked geographical locations could help them understand what a nuclear weapon would do to places they are familiar with. Striking with instantaneous speed and unleashing a firestorm of unimaginable proportions, a nuclear warhead can pulverize thousands of tons of earth, irradiating and ejecting it into the upper atmospheregradually spreading radioactive fallout over hundreds of miles. It consists of a map in which users can select a location and model the local impacts of a blast, while accounting for various factors, such as the power of the weapon and whether or not it detonates on (or near) the surface or up in the air. We also know that radioactive particles can travel remarkably far; a recent study found that remnants of radioactive carbon from Cold War nuclear bomb tests have been found all the way down in the Mariana Trench, the deepest point of the world's oceans.

Large particles fall to the ground near the explosion-site, but lighter particles and gases travel into the upper atmosphere. The blast area of destruction is only 5-7 miles from any nuclear target, so don't prepare against blast effects, which is very expensiverelocate instead. Fallout, however, can circulate around the .
