obspy.core.event.FocalMechanism¶
- class FocalMechanism(force_resource_id=True, *args, **kwargs)[source]¶
Bases: obspy.core.event.__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. Allowed values are the following:
- "manual"
- "automatic"
- evaluation_status (str, optional)
Evaluation status of FocalMechanism. Allowed values are the following:
- "preliminary"
- "confirmed"
- "reviewed"
- "final"
- "rejected"
- "reported"
- 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.
