WebThe amplitude of the seismic waves is therefore proportional to the energy released and is a measure of the magnitude of the earthquake. It was Charles Richter, in 1935, who proposed a method for measuring the magnitude of earthquakes starting from the measurement of the amplitudes recorded by a particular torsion seismometer, the Wood …

Earthquake - Properties of seismic waves Britannica
WebSeismic Waves There are two basic types of seismic waves: body waves which travel through the body of the earth and sur-face waveswhich travel around the surface of the earth. Body waves can be characterized as either primary or sec-ondary. The primary or P wave (Figure 2a) is the fastest (~5.5 km/sec in granite) (Bolt, 1993) of the body waves WebSeismic waves can also be caused by natural processes other than earthquakes and by human activities. Some are geological like the Menominee Crack. When magma moves toward the surface prior to volcanic eruptions, it produces seismic waves that can be used to forecast an eruption. WebSeismic reflection is the return of some of the energy from seismic waves that have penetrated downward from the surface or near‐surface, hit a rock boundary, and bounced back to the surface (Figure 2). Since the time of departure and return are known from the seismogram, the depth to the rock boundary can be calculated. Figure 2. day5 栄養ドリンク
