`pyrocko.io.quakeml`¶

QuakeML 1.2 input, output, and data model.

This modules provides support to read and write QuakeML version 1.2. It defines a hierarchy of Python objects, closely following the QuakeML data model.

QuakeML is a flexible, extensible and modular XML representation of seismological data which is intended to cover a broad range of fields of application in modern seismology. It covers basic seismic event description, including moment tensors.

For convenience and ease of use, this documentation contains excerpts from the QuakeML Manual. However, this information is not intended to be complete. Please refer to the QuakeML Manual for details.

Additional pick attributes like the horizontal slowness and backazimuth of the observed wave—especially if derived from array data—may further constrain the nature of the arrival.

class Event(**kwargs)[source]¶

Bases: pyrocko.guts.Object

Representation of a seismic event.

The Event 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. In standard QuakeML-BED, Origin, Magnitude, StationMagnitude, and FocalMechanism are child elements of Event. In BED-RT all these elements are on the same hierarchy level as child elements of EventParameters. The association of origins, magnitudes, and focal mechanisms to a particular event is expressed using references inside Event.
