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...

Geyser and volcano monitoring suffer from temporal, geographic, instrumental biases. We present a recording bias identified through multiyear of Steamboat in Yellowstone National Park, USA. Eruptions are the tallest any geyser world they produce broadband signals at two nearby stations Park Seismograph Network. In winter, we observe lower eruption signal amplitudes these seismometers. Instead s...

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...

Abstract Integrated Seismic Program (ISP) is a graphical user interface designed to facilitate and provide user-friendly framework for performing diverse common advanced tasks in seismological research. ISP composed of five main modules earthquake location, time–frequency analysis signal processing, implementation array techniques estimate the slowness vector, seismic moment tensor inversion, r...
