_summary_

Parameters:

  • overall_name (str)

  • segment_names (list)

  • search_patterns (Union[str, list])

  • excluded_names (Union[str, list])

  • tolerance (float)

  • smooth_trace_refinements (int)

  • trimming_gradient (float)

calculate_overall_dip_direction(tolerance=10.0)

Compares dip direction string (e.g. NW) with :return:

Parameters:

tolerance (float)

generate_sr_rake_points(depths, smoothing=True, km=False)

Generate strike and rake points for the fault system at specified depths.

Parameters:

  • depths (Union[np.ndarray, List[float]]) – Depths at which to generate strike and rake points

  • smoothing (bool, optional) – Whether to apply smoothing to the traces, defaults to True

  • km (bool, optional) – Whether depths are in kilometers, defaults to False

property sampled_dip

Dip value sampled from the fault trace. Used for calculating dip in depth contours. :return:

mesh_fault_surface(resolution=1000.0, spline_resolution=100.0, plane_fitting_eps=1e-05, check_mesh=False, check_strike_dip=False)

Generate a triangular mesh representing the fault surface.

This method creates a 3D triangular mesh of the fault surface by: 1. Fitting splines to depth contours 2. Fitting a plane to all contour points 3. Projecting contours onto the plane 4. Interpolating between contours using thin plate spline 5. Triangulating the resulting surface

Parameters:

  • resolution (float, optional) – Target spatial resolution of the mesh in meters, defaults to 1000.

  • spline_resolution (float, optional) – Point spacing for spline fitting in meters, defaults to 100.

  • plane_fitting_eps (float, optional) – Tolerance for plane fitting algorithm, defaults to 1.0e-5

  • check_mesh (bool, optional) – Whether to display visualization of the mesh for debugging, defaults to False

  • check_strike_dip (bool, optional) – Whether to print strike and dip information for debugging, defaults to False

Returns:

Triangular mesh representing the fault surface

Return type:

meshio.Mesh

mesh_simple_contours(depths, mesh_name=None, mesh_format='vtk', check_mesh=False, check_strike_dip=True, km=False)

Create a mesh from simple contours.

Parameters:

  • depths (Union[np.ndarray, List[float]]) – Array of depths for each contour

  • km (bool) – Whether the depths are in kilometers, defaults to False

  • mesh_name (str, optional) – Name of the output mesh file

  • mesh_format (str, optional) – Format of the output mesh file

  • check_mesh (bool, optional) – Whether to display visualization of the mesh for debugging, defaults to False

  • check_strike_dip (bool, optional) – Whether to print strike and dip information for debugging, defaults to False

Returns:

Triangular mesh representing the fault surface

Return type:

meshio.Mesh
