obspy.core.event.source.MomentTensor¶
- 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) 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) Resource identifier of the Green’s function used in moment tensor inversion.
- filter_id (ResourceIdentifier) 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) 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.
