 FDSN Event Web Service

URL Builder

The FDSN event web service returns event(earthquake) in QuakeML format (schema here). Events may be selected based on location, time, catalog, contributor and internal identifiers. By default, events are retrieved from the SCEDC catalog. These default results include the catalog's "primary origin" and "primary magnitude" for each event, they may optionally include all available origin and magnitude estimates. By default, results are returned in QuakeML format, but may also be requested in text format. Please limit your search to smaller time periods.

Note: Due to current limitations, we are no longer able to support the 'includeallorigins' option.
