estimate_wood_anderson_amplitude(paz, amplitude, timespan)[source]

Calculate the Wood-Anderson amplitude equivalent.

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.
