pyacs.lib.faultslip.v_to_n_ss.v_to_n_ss(ve, vn, strike)[source]

Decompose horizontal velocity into normal and strike-slip components.

Point is in the left-domain with respect to the fault. Shortening and right-lateral are positive; extension and left-lateral are negative.

Parameters:

  • ve (float or array-like) – East component of motion (any unit).

  • vn (float or array-like) – North component of motion (any unit).

  • strike (float or array-like) – Fault strike in decimal degrees.

Returns:

  • normal (float or numpy.ndarray) – Normal component, same units as ve, vn.

  • strike_slip (float or numpy.ndarray) – Strike-slip component, same units as ve, vn.
