What is a consequence of a shallow underwater burst?

A shallow underwater burst typically occurs when a nuclear weapon detonates just below the surface of the water but not deep enough to minimize the effects. One of the primary consequences of such a detonation includes the generation of large waves or tsunamis that can travel across the water, causing significant disruption in coastal areas. Additionally, the explosion can lead to extensive water contamination due to the dispersal of radioactive materials and other harmful substances into the surrounding water. This contamination poses a risk not only to marine ecosystems but also to human life if the contaminated water affects drinking or swimming water supplies. The combination of large waves and the pollutants created by the explosion underscores the severe impact of a shallow underwater burst on the environment and human activities.
