EMSC SeismicPortal Web Services

The catalogues are worldwide and begin in 1998; the primary EMSC-RTS catalogue begins in 2004 and is continuously updated, while geographic and small-magnitude coverage are not uniform. New origins normally appear within minutes, can be delayed until a confidence threshold is reached and may change during the first few days. The API supports time, geographic, depth and magnitude filters plus limit and offset parameters, but no maximum query size is stated.
