3.7. Amplitude Intensity Measures

imcalculator.get_amplitude_ims()[source]

Computes amplitude-based intensity measures.

Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV), and Peak Ground Displacement (PGD) are computed from the acceleration time series by successive trapezoidal integration.

Parameters:

None

Returns:

  • pga (float) – Peak ground acceleration (g).

  • pgv (float) – Peak ground velocity (m/s).

  • pgd (float) – Peak ground displacement (m).
