pyacs.lib.faultslip.v_to_rake.v_to_rake(ve, vn, strike, dip, style='inverse')[source]

Compute expected rake from relative horizontal velocity and fault geometry.

Parameters:

  • ve (float or numpy.ndarray) – East and north components of relative motion (any unit).

  • vn (float or numpy.ndarray) – East and north components of relative motion (any unit).

  • strike (float or numpy.ndarray) – Fault strike and dip in decimal degrees.

  • dip (float or numpy.ndarray) – Fault strike and dip in decimal degrees.

  • style (str, optional) – One of ‘inverse’, ‘normal’, ‘leftlateral’, ‘rightlateral’ to resolve ambiguity (hanging wall vs footwall). If None, first solution is returned.

Returns:

Rake in decimal degrees.

Return type:

float or numpy.ndarray

Notes

ve, vn alone are ambiguous (hanging wall vs footwall); style disambiguates.
