WebThe responses of conventional seismographs are such that earthquake waves in the period range of about 5 to 20 seconds are written with such large amplitudes an the seismograms that longer period waves cannot be observed. Consequently, in order to increase the observable range to substantially longer periods, I developed an electromagnetic strain …

WebExistence of surface acoustic waves(SAW) on a piezoelectric layer with the half-infinite elastic layer is investigated. This structure belongs to an open waveguide with the unbounded boundary in the transverse direction.Except for trapped modes, leaky modes have often been considered in SAW applications, which requires waves of low attenuation … Webother yielding the analogous horizontal Rayleigh-wave estimates. The identification and separation of Love waves by this method may be obtained by matching horizontal Rayleigh-wave peaks one-to-one with those obtained from the LPZ components. The remaining peaks, therefore, represent Love-wave contributions. Because Rayleigh waves are surface waves, the amplitude of such waves generated by an earthquake generally decreases exponentially with the depth of the hypocenter (focus). However, large earthquakes may generate Rayleigh waves that travel around the Earth several times before dissipating. In seismology longitudinal and shear waves are known as P-waves and S-waves, … cry timon
