Limit to events on or after the specified start time. Limit to events on or before the specified end time. Limit to events with a latitude larger than or equal to the specified minimum. Limit to events with a latitude smaller than or equal to the specified maximum. Limit to events with a longitude larger than or equal to the specified minimum. Limit to events with a longitude smaller than or equal to the specified maximum. Specify the latitude to be used for a radius search. Specify the longitude to be used for a radius search. Limit to events within the specified minimum number of degrees from the geographical point defined by the latitude and longitude parameters. Limit to events within the specified maximum number of degrees from the geographical point defined by the latitude and longitude parameters. Limit to events with depth more than or equal to the specified minimum. Limit to events with depth less than or equal to the specified maximum. Limit to events with a magnitude larger than or equal to the specified minimum. Limit to events with a magnitude smaller than or equal to the specified maximum. Only include events with a preferred magnitude of a specific type. Note: This implementation is not according to the standard but QuakeLink only indexes the preferred magnitude of each event. Limit to events with a specified eventType. The parameter value can be a single item or a comma-separated list of items. Allowed values are from QuakeML or 'unknown' if eventType is not given. Specify if all origins, magnitudes and focal mechanisms for the event should be included. Identical to 'includeallmagnitudes'. Specify if all origins, magnitudes and focal mechanisms for the event should be included. Identical to 'includeallorigins'. Specify if phase arrivals should be included. Identical to 'include=arrs'. Select a specific event by ID. Limit the results to the specified number of events. Return results starting at the event count specified. Note: The FDSNWS specification uses a weird definition of an offset where the first element is not addressed by 'offset=0' but 'offset=1'. So the implementation will decrement the offset value by one when generating the SQL database query. Result order. Limit to events contributed by a specified agency. Limit to events updated after the specified time. Specify the desired output format. Select status code for 'no data' which is either '204' or '404'. Request for specific event revision. May only be combined with 'eventid' request parameter. Limit to events created by a specific author. The availability of this option depends on the server configuration. Limit events by cummulated evaluation status and evaluation mode of the origin expressed by one character. Limit events by evaluation status of the origin. The parameter value can be a single item or a comma-separated list of items. Limit events by evaluation mode of the origin. Limit events by region description. Similar to 'updateafter', limit to events updated before the specified time. Limit to events with a minimum number of phases contributing to a origin solution. Limit to events with a maximum number of phases contributing to a origin solution. List of XML objects to include in result document. This parameter may be repeated or individual values may be defined as a comma-separated list. Adds pick information. Identical to 'include=picks'. Adds amplitude information. Identical to 'include=amps'. Adds station magnitude information. Identical to 'include=stamags'. Adds station moment tensor contributions. Identical to 'include=stamts'. Request native XML format disabling all other format filter. The availability of this option depends on the server configuration. Control gzip compression of result document. If undefined the 'Accept-Encoding' HTTP header is evaluated instead. If enabled the 'Content-Disposition' HTTP response header is set to 'attachment' including a meaningful file name. Controls formatted (pretty print) output.
