1. an extremely large ocean wave, especially one caused by seismic activity or extreme weather
Usage: oceanography
2. a theoretical or hypothetical wave of extraordinary magnitude in physics
Usage: physics; theoretical

Examples

• The tsunami created a superwave that reached heights of over 100 feet.
• Scientists study superwaves to better understand ocean dynamics.
• The storm generated a superwave that damaged coastal structures.
• Researchers are investigating the formation of superwaves in deep ocean waters.
• The theoretical model predicted the existence of superwaves under extreme conditions.
• Coastal communities must prepare for the possibility of superwaves during major storms.
