class Event(force_resource_id=True, *args, **kwargs)[source]

Bases: obspy.core.event.base.__Event

The class Event describes a seismic event which does not necessarily need to be a tectonic earthquake. An event is usually associated with one or more origins, which contain information about focal time and geographical location of the event. Multiple origins can cover automatic and manual locations, a set of location from different agencies, locations generated with different location programs and earth models, etc. Furthermore, an event is usually associated with one or more magnitudes, and with one or more focal mechanism determinations.

  • resource_id (ResourceIdentifier) Resource identifier of Event.
  • 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.
  • event_type (str, optional) Describes the type of an event. See EventType for allowed values.
  • event_type_certainty (str, optional) Denotes how certain the information on event type is. See EventTypeCertainty for allowed values.
  • creation_info (CreationInfo, optional) Creation information used to describe author, version, and creation time.
  • event_descriptions (list of EventDescription) Additional event description, like earthquake name, Flinn-Engdahl region, etc.
  • comments (list of Comment, optional) Additional comments.
  • picks (list of Pick) Picks associated with the event.
  • amplitudes (list of Amplitude) Amplitudes associated with the event.
  • focal_mechanisms (list of FocalMechanism) Focal mechanisms associated with the event
  • origins (list of Origin) Origins associated with the event.
  • magnitudes (list of Magnitude) Magnitudes associated with the event.
  • station_magnitudes (list of StationMagnitude) Station magnitudes associated with the event.

Public Methods

plot Plot event location and/or the preferred focal mechanism and radiation pattern.
pop If key is not found, d is returned if given, otherwise KeyError is raised.
popitem as a 2-tuple; but raise KeyError if D is empty.
preferred_focal_mechanism Returns the preferred focal mechanism
preferred_magnitude Returns the preferred magnitude
preferred_origin Returns the preferred origin
short_str Returns a short string representation of the current Event.
write Saves event information into a file.

Private Methods


Private methods are mainly for internal/developer use and their API might change without notice.

_pretty_str Return better readable string representation of AttribDict object.

Special Methods

__dir__ default dir() implementation
__eq__ Two instances are considered equal if all attributes and all lists
__format__ default object formatter
__getattr__ Py3k hasattr() expects an AttributeError no KeyError to be
__new__ Create and return a new object.
__reduce__ helper for pickle
__reduce_ex__ helper for pickle
__setattr__ Custom property implementation that works if the class is
__sizeof__ size of object in memory, in bytes
__str__ Print a short summary at the top.
