EarthquakesWater hazards
Quick Answer
A seiche is a standing wave that sloshes back and forth in a lake, bay, or harbor, often triggered by earthquakes or strong winds.
The Full Story
Seiches happen when water in an enclosed or semi-enclosed basin is displaced and oscillates at its natural frequency. Earthquakes are a classic trigger, but sudden atmospheric pressure changes and storms can also set them off. In harbors and lakes, seiches can damage docks, boats, and shoreline structures. They are sometimes mistaken for tides, but unlike tides, seiches are driven by resonance in the basin.
