Which of the following is NOT an effect of a nuclear explosion?

A nuclear explosion creates several distinct and immediate effects, including blast waves, intense heat, and radiation. The blast effect results from the rapid expansion of air heated by the explosion, creating a shockwave that can cause widespread destruction. The heat generated can ignite fires and cause severe burns or fatalities to anyone in proximity. Radiation is released during a nuclear explosion and can have both immediate and long-term health effects on exposed populations.

Conversely, a tsunami is not a direct effect of a nuclear explosion. While underwater nuclear detonations can generate tsunamis, surface or above-ground explosions do not create this phenomenon. Tsunamis are typically associated with seismic activity, such as earthquakes, rather than nuclear explosions. Thus, the absence of a tsunami as a direct consequence highlights the unique nature of the other effects related to a nuclear blast.
