Earthquake magnitude and frequency
WebMagnitudes are based on a logarithmic scale (base 10). What this means is that for each whole number you go up on the magnitude scale, the amplitude of the ground motion recorded by a seismograph goes up ten times. Using this scale, a magnitude 5 earthquake would result in ten times the level of ground shaking as a magnitude 4 earthquake (and ... WebDec 20, 2007 · At a givensite, an earthquake magnitude could be determined from τc and the peak ground-motionvelocity (PGV) could be estimated from Pd. In this method, incoming strong motion acceleration signals are recursively converted to ground velocity and displacement. ... filtered with a one-way Butterworth high-pass filter with a cutoff …
