Parameters: |
- resource_id (ResourceIdentifier) Resource identifier of Origin.
- 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.
- time (UTCDateTime) Focal time.
- time_errors (AttribDict) AttribDict containing error quantities.
- longitude (float) Hypocenter longitude, with respect to the World Geodetic
System 1984 (WGS84) reference system. Unit: deg
- longitude_errors (AttribDict) AttribDict containing error quantities.
- latitude (float) Hypocenter latitude, with respect to the WGS84 reference
system. Unit: deg
- latitude_errors (AttribDict) AttribDict containing error quantities.
- depth (float, optional) Depth of hypocenter with respect to the nominal sea level
given by the WGS84 geoid. Positive values indicate hypocenters below
sea level. For shallow hypocenters, the depth value can be negative.
Note: Other standards use different conventions for depth measurement.
As an example, GSE2.0, defines depth with respect to the local surface.
If event data is converted from other formats to QuakeML, depth values
may have to be modified accordingly. Unit: m
- depth_errors (AttribDict) AttribDict containing error quantities.
- depth_type (str, optional)
Type of depth determination. Allowed values are the
following:
- "from location"
- "from moment tensor inversion"
- "from modeling of broad-band P waveforms"
- "constrained by depth phases"
- "constrained by direct phases"
- "constrained by depth and direct phases"
- "operator assigned"
- "other"
- time_fixed (bool, optional) Boolean flag. True if focal time was kept fixed for
computation of the Origin.
- epicenter_fixed (bool, optional) Boolean flag. True if epicenter was kept fixed for
computation of Origin.
- reference_system_id (ResourceIdentifier,
optional) Identifies the reference system used for
hypocenter determination. This is only necessary if a modified version
of the standard (with local extensions) is used that provides a
non-standard coordinate system.
- method_id (ResourceIdentifier, optional) Identifies the method used for locating the event.
- earth_model_id (ResourceIdentifier,
optional) Identifies the earth model used in method_id.
- arrivals (list of Arrival, optional) List of arrivals associated with the origin.
- composite_times (list of CompositeTime,
optional) Supplementary information on time of rupture start.
Complex descriptions of focal times of historic events are possible,
see description of the CompositeTime type. Note that even if
compositeTime is used, the mandatory time attribute has to be set, too.
It has to be set to the single point in time (with uncertainties
allowed) that is most characteristic for the event.
- quality (OriginQuality, optional) Additional parameters describing the quality of an Origin
determination.
- origin_type (str, optional)
Describes the origin type. Allowed values are the
following:
- "hypocenter"
- "centroid"
- "amplitude"
- "macroseismic"
- "rupture start"
- "rupture end"
- origin_uncertainty (OriginUncertainty,
optional) Describes the location uncertainties of an
origin.
- region (str, optional) Can be used to decribe the geographical region of the
epicenter location. Useful if an event has multiple origins from
different agencies, and these have different region designations. Note
that an event-wide region can be defined in the description attribute
of an Event object. The user has to take care that this information
corresponds to the region attribute of the preferred Origin.
- evaluation_mode (str, optional)
Evaluation mode of Origin. Allowed values are the
following:
- evaluation_status (str, optional)
Evaluation status of Origin. Allowed values are
the following:
- "preliminary"
- "confirmed"
- "reviewed"
- "final"
- "rejected"
- "reported"
- comments (list of Comment, optional) Additional comments.
- creation_info (CreationInfo, optional) Creation information used to describe author,
version, and creation time.
