Can a Tsunami Strike the Gulf of Mexico?

Low Probability, Not Zero Risk

While the Gulf of Mexico is far less tsunami-prone than the Pacific, several mechanisms could generate waves there:

Potential Sources

• Submarine earthquakes: Rare but documented; the 2006 Gulf of Mexico quake (M6.0) produced a small tsunami.
• Submarine landslides: The continental slope has failed historically, displacing water.
• Distant tsunamis: Caribbean or South American quakes can send waves across the basin (e.g., 1946 Dominican Republic tsunami recorded in Gulf tide gauges).
• Volcanic eruptions: No active Gulf volcanoes, but Caribbean eruptions (e.g., Kick-'em-Jenny) could propagate waves.

Mitigating Factors

The Gulf's shallow continental shelf and complex coastline dissipate wave energy. However, low-lying coastal communities should maintain awareness and heed NOAA tsunami advisories.
