The NCEDC provides a number of web services that provide improved functionality formerly provided by the FISSURES Data Handling Interface (DHI) system. FISSURES DHI, initially developed by IRIS, defined a client/server system for querying and delivering station and channel metadata as well as time series data. IRIS and all other data centers have already retired their FISSURES DHI services.

The FDSN-compatible and NCEDC web services are available at

The NCEDC will shut down its FISSURES DHI servers and primary DHI name server for DHI server lookups on Fri Jan 20 2017. Please contact the NCEDC at if you have any questions.
