The flexible approach of QuakeML allows further extensions of the standard in order to represent waveform data, macroseismic information, probability density functions, slip distributions, shake maps, and others.

For that purpose, QuakeML proposes a URI-based format for unique, location-independent identifiers of seismological resources which are assigned by approved naming authorities.

This is the version that is used in results of event queries to International Federation of Digital Seismograph Networks (FDSN) web services and is supported by data centers around the world, such as the European Seismic Portal.

QuakeML up to version 1.2 covered (only) a basic seismic event description, whereas from v2.0 many new thematic packages will be available, and are currently under development.

It provides a library of classes for earthquake catalog handling and computations, and plot routines for visualizing the obtained results.
