Distant earthquakes: Major earthquakes in other parts of the world, such as the Caribbean or South America, could generate a tsunami that reaches the Atlantic coast of the United States. However, these events are relatively uncommon and depend on the magnitude and location of the earthquake.
Coastal landslides: Underwater landslides or avalanches triggered by earthquakes or volcanic eruptions can also create a tsunami. The continental slope off the New Jersey coast is relatively steep, and there have been some documented submarine landslides in the region. However, the likelihood of a large-scale landslide capable of generating a major tsunami is considered low.
Meteotsunamis: Meteotsunamis are rare, short-lived tsunamis caused by rapid atmospheric pressure changes associated with weather events such as fast-moving thunderstorms or hurricanes. These tsunamis are unpredictable and can impact coastal regions. While Atlantic City is prone to severe thunderstorms and hurricanes, meteotsunamis are not known to be a significant threat in the area.
Although Atlantic City's risk of a major tsunami is relatively low compared to other coastal regions, it's essential for the city to be prepared. This includes maintaining early warning systems, developing evacuation plans, and educating the public about tsunami risks and safety measures.
