A surface wave is a type of wave that travels along the interface between two different media, such as air and water. These waves are commonly observed in oceans and lakes, where they create ripples and larger waves. Surface waves are characterized by their motion, where particles move in circular or elliptical paths, resulting in energy transfer without significant movement of the medium itself. In the context of seismology, surface waves are generated by earthquakes and travel along the Earth's surface. They are typically slower than body waves, which move through the Earth's interior, but can cause more damage due to their larger amplitude and longer duration. Understanding surface waves is crucial for assessing earthquake impacts and designing resilient structures.
