class
FocalMechanism
(force_resource_id=True, *args, **kwargs)[source]¶ Bases:
obspy.core.event.base.__FocalMechanism
This class describes the focal mechanism of an event. It includes different descriptions like nodal planes, principal axes, and a moment tensor. The moment tensor description is provided by objects of the class MomentTensor which can be specified as child elements of FocalMechanism.
- Parameters
resource_id (
ResourceIdentifier
) – Resource identifier of FocalMechanism.force_resource_id (bool, optional) – If set to False, the automatic initialization of resource_id attribute in case it is not specified will be skipped.
triggering_origin_id (
ResourceIdentifier
, optional) – Refers to the resource_id of the triggering origin.nodal_planes (
NodalPlanes
, optional) – Nodal planes of the focal mechanism.principal_axes (
PrincipalAxes
, optional) – Principal axes of the focal mechanism.azimuthal_gap (float, optional) – Largest azimuthal gap in distribution of stations used for determination of focal mechanism. Unit: deg
station_polarity_count (int, optional) –
misfit (float, optional) – Fraction of misfit polarities in a first-motion focal mechanism determination. Decimal fraction between 0 and 1.
station_distribution_ratio (float, optional) – Station distribution ratio (STDR) parameter. Indicates how the stations are distributed about the focal sphere (Reasenberg and Oppenheimer 1985). Decimal fraction between 0 and 1.
method_id (
ResourceIdentifier
, optional) – Resource identifier of the method used for determination of the focal mechanism.waveform_id (list of
WaveformStreamID
, optional) – Refers to a set of waveform streams from which the focal mechanism was derived.evaluation_mode (str, optional) – Evaluation mode of FocalMechanism. See
EvaluationMode
for allowed values.evaluation_status (str, optional) – Evaluation status of FocalMechanism. See
EvaluationStatus
for allowed values.moment_tensor (
MomentTensor
, optional) – Moment tensor description for this focal mechanism.comments (list of
Comment
, optional) – Additional comments.creation_info (
CreationInfo
, optional) – Creation information used to describe author, version, and creation time.

Public Methods
If key is not found, d is returned if given, otherwise KeyError is raised.
as a 2-tuple; but raise KeyError if D is empty.
If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v
Private Methods
Warning
Private methods are mainly for internal/developer use and their API might change without notice.
Return better readable string representation of AttribDict object.
Special Methods
reset resource_id’s object_id after deep copy to allow the object specific behavior of get_referred_object
Default dir() implementation.
Two instances are considered equal if all attributes and all lists are identical.
Default object formatter.
Py3k hasattr() expects an AttributeError no KeyError to be raised if the attribute is not found.
This method is called when a class is subclassed.
Create and return a new object.
Helper for pickle.
Helper for pickle.
Custom property implementation that works if the class is inheriting from AttribDict.
Size of object in memory, in bytes.
Fairly extensive in an attempt to cover several use cases.
Abstract classes can override this to customize issubclass().
