The Ocean Wave Scientists Thought Was Impossible #roguewaves #shipwreck

Why It Matters

Recognizing rogue waves as a credible hazard reshaped maritime safety, ship design and risk assessment, highlighting limits in forecasting and the need for improved monitoring to prevent future losses at sea.

Summary

In December 1978 the German cargo ship MS Moonshin and its crew vanished during its 62nd voyage, a mystery that went unsolved for nearly two decades. Investigators later concluded the likely cause was a rogue wave — an extreme surface wave, possibly exceeding 80 feet in this case, that appears suddenly and is more than twice the height of surrounding waves. Rogue waves differ from tsunamis because they form on the open ocean surface rather than from seismic activity and can occur far from shore. The phenomenon is relative in scale (a 4‑ft wave can be “rogue” amid 2‑ft seas) and remains not fully understood by scientists.
