obspy.core.event.catalog.Catalog.write

Catalog.write(filename, format, **kwargs)

Saves catalog into a file.

Parameters:

• filename (str) – The name of the file to write.

• format (str) – The file format to use (e.g. "QUAKEML"). See the Supported Formats section below for a list of supported formats.

• kwargs – Additional keyword arguments passed to the underlying plugin’s writer method.

Example

>>> from obspy import read_events
>>> catalog = read_events()
>>> catalog.write("example.xml", format="QUAKEML")  

Writing single events into files with meaningful filenames can be done e.g. using event.id

>>> for ev in catalog:  
...     filename = str(ev.resource_id) + ".xml"
...     ev.write(filename, format="QUAKEML")
