obspy.core.event.source.MomentTensor
- class MomentTensor(force_resource_id=True, *args, **kwargs)[source]
Bases:
AbstractEventTypeWithResourceID
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.
Note
For handling additional information not covered by the QuakeML standard and how to output it to QuakeML see the ObsPy Tutorial.
Attributes
Public Methods
Clear the class :return: |

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. |

Private Methods
Warning
Private methods are mainly for internal/developer use and their API might change without notice.
- MomentTensor._cast_type(key, value)
Cast type of value to type required in _types dict.
- Parameters:
key (str) – The key from __setattr__.
value – The value being set to key.
- Returns:
value cast to correct type.
- MomentTensor._pretty_str(priorized_keys=[], min_label_length=16)
Return better readable string representation of AttribDict object.
- Parameters:
- Returns:
String representation of current AttribDict object.
- MomentTensor._repr_pretty_(p, cycle)
Special Methods
- MomentTensor.__bool__()
- classmethod MomentTensor.__class_getitem__()
Represent a PEP 585 generic type
E.g. for t = list[int], t.__origin__ is list and t.__args__ is (int,).
- MomentTensor.__contains__(key)
- MomentTensor.__delattr__(name)
- MomentTensor.__delitem__(name)
- MomentTensor.__dir__()
Default dir() implementation.
- MomentTensor.__eq__(other)
Two instances are considered equal if all attributes and all lists are identical.
- MomentTensor.__format__(format_spec, /)
Default object formatter.
- MomentTensor.__ge__(value, /)
Return self>=value.
- MomentTensor.__getattr__(name, default=None)
Py3k hasattr() expects an AttributeError no KeyError to be raised if the attribute is not found.
- MomentTensor.__getattribute__(name, /)
Return getattr(self, name).
- MomentTensor.__getitem__(name, default=None)
- MomentTensor.__gt__(value, /)
Return self>value.
- MomentTensor.__init__(force_resource_id=True, *args, **kwargs)
- MomentTensor.__init_subclass__()
This method is called when a class is subclassed.
The default implementation does nothing. It may be overridden to extend subclasses.
- MomentTensor.__iter__()
- MomentTensor.__le__(value, /)
Return self<=value.
- MomentTensor.__len__()
- MomentTensor.__lt__(value, /)
Return self<value.
- MomentTensor.__ne__(other)
- MomentTensor.__new__(**kwargs)
- MomentTensor.__reduce__()
Helper for pickle.
- MomentTensor.__reduce_ex__(protocol, /)
Helper for pickle.
- MomentTensor.__repr__()
- MomentTensor.__setattr__(name, value)
Custom property implementation that works if the class is inheriting from AttribDict.
- MomentTensor.__setitem__(key, value)
- MomentTensor.__sizeof__()
Size of object in memory, in bytes.
- MomentTensor.__str__(force_one_line=False)
Fairly extensive in an attempt to cover several use cases. It is always possible to change it in the child class.
- classmethod MomentTensor.__subclasshook__(C)
