31. In solids, mechanical waves can take many forms including longitudinal waves, transverse waves and surface waves . 32. Breaking of water surface waves may occur anywhere that the amplitude is sufficient, including in mid-ocean. 33. The earthquake had an estimated magnitude of 7.2 ?0.3 on the surface wave magnitude scale. 34. Deep-focus earthquakes give rise to minimal surface waves . 35. Physically, seismic noise consists mostly of surface waves . 36. Another tidal wave technology harvests energy from surface waves or from pressure fluctuations below the sea surface. 37. Surface waves therefore decay more slowly with distance than do body waves, which travel in three dimensions.38. Within microwave field theory, the interface of a dielectric and conductor supports " surface wave transmission ". 39. This is because the material can suppress surface wave propagation within the prescribed range of forbidden frequencies. 40. The surface wave is also very dependent upon the nature of the ground over which the signal travels.
