Wanderlust World Wanderlust World While a tsunami striking Atlantic City is theoretically possible, the risk is relatively low compared to Pacific coastal regions. The U.S. East Coast is less tectonically active, but several mechanisms could generate a tsunami:
Large quakes in the Caribbean or South America might produce a tsunami reaching the Atlantic coast, though such events are uncommon and depend on magnitude and location.
Underwater landslides triggered by quakes or volcanic eruptions can create tsunamis. The continental slope off New Jersey is steep, with documented submarine landslides, but a major landslide capable of a significant tsunami is considered unlikely.
Rapid atmospheric pressure changes from fast-moving thunderstorms or hurricanes can cause short-lived meteotsunamis. Atlantic City experiences severe storms, yet meteotsunamis are not a major documented threat.
Despite the low probability, preparedness—early warning systems, evacuation plans, and public education—remains essential.
