estimate_wood_anderson_amplitude(paz, amplitude, timespan)[source]

Convert amplitude in counts measured of instrument with given Poles and Zeros information for use in estimate_magnitude(). Amplitude should be measured as full peak to peak amplitude, timespan as difference of the two readings.

Parameters:
  • paz PAZ of the instrument [m/s] or list of the same
  • amplitude Peak to peak amplitude [counts] or list of the same
  • timespan Timespan of peak to peak amplitude [s] or list of the same
Returns:

Simulated zero to peak displacement amplitude on Wood Anderson seismometer [mm] for use in local magnitude estimation.
