Surface wave magnitude
WebMar 5, 2024 · A commonly used earthquake scale is the surface wave magnitude scale, or MS, which measures the largest deflection of the needle on the seismograph for a surface wave that takes about twenty seconds to pass a point (which is about the same frequency as some ocean waves).

WebIt can also be estimated from seismic data if the seismometer is tuned to detect long-period body waves. Surface wave (MS) 5 to 8: 20 to 180° A magnitude for distant earthquakes based on the amplitude of surface waves measured at a period near 20 s. P-wave: 2 to 8: Local: Based on the amplitude of P-waves. WebOther articles where surface-wave magnitude scale is discussed: Richter scale: Modified Richter scales: …traveling within Earth) and the surface-wave magnitude scale (MS, which calculates the magnitude of Love and Rayleigh waves traveling along Earth’s surface). Although both scales continued to make use of seismographs and peak wave amplitudes, …
WebMar 20, 2024 · Measuring the seismic moment allows for the development of a more uniform, scientific scale of an earthquake’s relative size based on classical mechanics, called moment magnitude ( MW ). MW can be … WebLove Waves. One kind of surface wave is called a Love wave, named after British mathematician A. E. H. Love, who worked out the mathematical model for this wave type in 1911. Love waves produce entirely horizontal motion. The amplitude is largest at the surface and diminishes with greater depth. A Love wave travels through a medium.
WebSurface wave magnitude, Ms, is measured using the largest amplitude of the surface waves. The general equation has the form: Ms = log (A¦T)+ + 1.66 log (Δ) +3.3. Often the largest amplitude Rayleigh waves are generally at a period of 20s. In this case the general equation becomes: Ms = logA20 + 1.66log (Δ) +2.0. WebThe surface-wave magnitude scale, variously denoted as Ms, MS, and Ms, is based on a procedure developed by Beno Gutenberg in 1942 [39] for measuring shallow earthquakes stronger or more distant than Richter's original scale could handle.
