pyacs.lib.faultslip.rake_from_slip_az.rake_from_slip_az

pyacs.lib.faultslip.rake_from_slip_az.rake_from_slip_az(strike, dip, slipdir, motion_type)[source]

Predict rake from horizontal slip direction and motion style.

Input parameters can be single float or 1D numpy array.

Parameters:

  • strike (float or numpy.ndarray) – Fault strike from north in decimal degrees.

  • dip (float or numpy.ndarray) – Fault dip from north in decimal degrees.

  • slipdir (float or numpy.ndarray) – Slip direction (azimuth) in decimal degrees.

  • motion_type (str) – Motion style (e.g. ‘inverse’, ‘normal’, ‘leftlateral’, ‘rightlateral’).

Returns:

Rake in decimal degrees.

Return type:

float or numpy.ndarray

Notes

Style needs to be provided to ensure the correct sense of slip.
