A method is presented for determining the local magnitude, NIL, from records from seismoscopes and similar instruments. The technique extrapolates the maximum response of the standard Wood-Anderson seismograph, which determines ML, from the maximum response of the seismoscope. The standard deviation of the steady-state response of an oscillator subjected to white noise excitation is used to der...

Abstract In order to meet the national intelligent development needs of coal mines, construct smart improve their safety production levels and finally realize vision flexible manpower line unmanned development, application 5G communication technology in seismographs for underground mines was discussed this study based on history advantages technology. Next, main scenarios were explored by combi...

Reduction of seismic velocities has been employed to study the hydration incoming plates and forearc mantle in recent years. However, few constraints have obtained Southern Mariana Trench. We use an ocean bottom seismograph (OBS) deployment conduct Rayleigh wave tomographic studies derive SV-wave velocity structure near Measured group phase as a function period are inverted determine using Baye...
