... The farther a seismograph station is from an earthquake epicenter, the longer it will take for seismic waves to arrive. The time lag between the first shaking due to P waves and due to S waves also increases with distance from the epicenter. This time lag allows seismologists to precisely calculate ...

Assessing intraplate earthquake hazards from satellite geopotential field observations
... seismograms were computed using a full wavenumber integration method that includes all reverberations, surface reflections, and surface waves. The maximum frequency of the calculated seismograms was 5 Hz since the Nyquist frequency of the LRSM short-period data is 10 Hz. The response was peaked at 3 ...
