class
MomentTensor
(force_resource_id=True, *args, **kwargs)[source]¶ Bases:
obspy.core.event.base.__MomentTensor
This class represents a moment tensor solution for an event. It is an optional part of a FocalMechanism description.
- Parameters
resource_id (
ResourceIdentifier
) – Resource identifier of MomentTensor.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.
derived_origin_id (
ResourceIdentifier
) – Refers to the resource_id of the Origin derived in the moment tensor inversion.moment_magnitude_id (
ResourceIdentifier
, optional) – Refers to the publicID of the Magnitude object which represents the derived moment magnitude.scalar_moment (float, optional) – Scalar moment as derived in moment tensor inversion. Unit: Nm
scalar_moment_errors (
QuantityError
) – AttribDict containing error quantities.tensor (
Tensor
, optional) – Tensor object holding the moment tensor elements.variance (float, optional) – Variance of moment tensor inversion.
variance_reduction (float, optional) – Variance reduction of moment tensor inversion, given in percent (Dreger 2003). This is a goodness-of-fit measure.
double_couple (float, optional) – Double couple parameter obtained from moment tensor inversion (decimal fraction between 0 and 1).
clvd (float, optional) – CLVD (compensated linear vector dipole) parameter obtained from moment tensor inversion (decimal fraction between 0 and 1).
iso (float, optional) – Isotropic part obtained from moment tensor inversion (decimal fraction between 0 and 1).
greens_function_id (
ResourceIdentifier
, optional) – Resource identifier of the Green’s function used in moment tensor inversion.filter_id (
ResourceIdentifier
, optional) – Resource identifier of the filter setup used in moment tensor inversion.source_time_function (
SourceTimeFunction
, optional) – Source time function used in moment-tensor inversion.data_used (list of
DataUsed
, optional) – Describes waveform data used for moment-tensor inversion.method_id (
ResourceIdentifier
, optional) – Resource identifier of the method used for moment-tensor inversion.category (str, optional) – Moment tensor category. See
MomentTensorCategory
for allowed values.inversion_type (str, optional) – Moment tensor inversion type. Users should avoid to give contradictory information in inversion_type and method_id. See
MTInversionType
for allowed values.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().
