Sismoazur FDSNWS Event Web Service

The event Web service provides access to contributed origin and magnitude estimates in QuakeML format. Events may be filtered e.g. by hypocenter, time and magnitude parameters. The request type is HTTP-GET only. Please refer to http://www.fdsn.org/webservice for a complete service description.

Usage of the query method

Group Parameter Abbrevation Default Minimum Maximum Type Units Description
time constraints
starttime start [Any] [Any Valid Time] time UTC Limit to events on or after the specified start time.
endtime end [Any] [Any Valid Time] time UTC Limit to events on or before the specified end time.
geographic constraints
minlatitude minlat -90.0 -90.0 90.0 float degrees Limit to events with a latitude larger than or equal to the specified minimum.
maxlatitude maxlat 90.0 -90.0 90.0 float degrees Limit to events with a latitude smaller than or equal to the specified maximum.
minlongitude minlat -180.0 -180.0 180.0 float degrees Limit to events with a longitude larger than or equal to the specified minimum.
maxlongitude maxlat 180.0 -180.0 180.0 float degrees Limit to events with a longitude smaller than or equal to the specified maximum.
output constraints
format xml One of: xml, text or json string [Not Applicable] Specify format of result, either ‘xml’ (default), ‘text’ or ‘json’. If this parameter is not specified the service must return QuakeML.
nodata 204 One of: 204 or 404 string [Not Applicable] Select status code for “no data”, either ‘204’ (default) or ‘404’.
service-specific constraints
mindepth [Any] [Any] [Any] float kilometers Limit to events with depth more than the specified minimum.
maxdepth [Any] [Any] [Any] float kilometers Limit to events with depth less than the specified minimum.
minmagnitude minmag [Any] [Any] [Any] float defined by the Limit to events with a magnitude larger than the specified minimum.
maxmagnitude maxmag [Any] [Any] [Any] float mag type Limit to events with a magnitude smaller than the specified minimum.
magnitudetype magtype [Any] [Not Applicable] string [Not Applicable] Specify a magnitude type to use for testing the minimum and maximum limits.
includeallorigins FALSE [Not Applicable] boolean [Not Applicable] Specify if all origins for the event should be included, default is data center dependent but is suggested to be the preferred origin only.
includeallmagnitudes FALSE [Not Applicable] boolean [Not Applicable] Specify if all magnitudes for the event should be included, default is data center dependent but is suggested to be the preferred magnitude only.
includearrivals FALSE [Not Applicable] boolean [Not Applicable] Specify if phase arrivals should be included.
eventid [Any] [Not Applicable] string [Not Applicable] Select a specific event by ID; event identifiers are data center specific.
limit [Any] 1 [Any Positive] integer [Not Applicable] Limit the results to the specified number of events.
offset 1 1 [Any Positive] integer [Not Applicable] Return results starting at the event count specified, starting at 1.
orderby time One of: time, time-asc, magnitude or magnitude-asc string [Not Applicable] Order the result by time or magnitude with the following possibilities:
time: order by origin descending time
time-asc: order by origin ascending time
magnitude: order by descending magnitude
magnitude-asc: order by ascending magnitude
non-standard constraints
includefocalmechanism FALSE [Not Applicable] boolean [Not Applicable] Include focal mechanism information when available (effective only for json output).
includeshakemap FALSE [Not Applicable] boolean [Not Applicable] Include shakemap information when available (effective only for json output).
requirefocalmechanism FALSE [Not Applicable] boolean [Not Applicable] Filter events to keep only those that have focal mechanism.
requireshakemap FALSE [Not Applicable] boolean [Not Applicable] Filter events to keep only those that have shakemap.
eventtype [ANY] [Not Applicable] string [Not Applicable] Filter events to keep only those that match the given event type. Multiple event types can be given separated by comma (','). The valid event types are listed below. If at least one given event type is not valid, the request return a 400 error code.
