obspy.core.event.Axis

class Axis(*args, **kwargs)[source]

Bases: obspy.core.event.__Axis

This class describes an eigenvector of a moment tensor expressed in its principal-axes system. It uses the angles azimuth, plunge, and the eigenvalue length.

Parameters:azimuth (float) Azimuth of eigenvector of moment tensor expressed in

principal-axes system. Measured clockwise from South-North direction at epicenter. Unit: deg :type azimuth_errors: AttribDict :param azimuth_errors: AttribDict containing error quantities. :type plunge: float :param plunge: Plunge of eigenvector of moment tensor expressed in

principal-axes system. Measured against downward vertical direction at epicenter. Unit: deg
Parameters:
  • plunge_errors (AttribDict) AttribDict containing error quantities.
  • length (float) Eigenvalue of moment tensor expressed in principal-axes system. Unit: Nm
  • length_errors (AttribDict) AttribDict containing error quantities.
