Lamb waves — propagate in solid plates. They are elastic waves whose particle motion lies in the plane defined by the plate normal and the direction of wave propagation. In 1917, the English mathematician Horace Lamb published his classic analysis and… … Wikipedia
Seismic tomography — is a methodology for estimating the earth s properties. In the seismology community, seismic tomography is just a part of seismic imaging, and usually has a more specific purpose to estimate properties such as propagating velocities of… … Wikipedia
Nankai Trough — The Nankai Trough 南海トラフ (Nankai Torafu?) is a submarine trough located south of Japan s island of Honshū, extending approximately 900 km offshore. In plate tectonics, the Nankai Trough marks a subduction zone that is caused by subduction of… … Wikipedia

Speed of sound — Sound is a vibration that travels through an elastic medium as a wave. The speed of sound describes how much distance such a wave travels in a certain amount of time. In SI Units with dry air at 20 °C (68 °F), the speed of sound is 343 m/s. This… … Wikipedia
