Activities of US regional networks are coordinated by the USGS
(ANSS). Archived
waveform data are distributed through a variety of data centers,
including IRIS. A regional network can be defined as any network
of seismic installations that are within a restricted geographic
region and normally operated by a single network operator.
IRIS receives data from several U.S. and non-U.S. regional networks.
You can use SeismiQuery
- our on-line database browsing tool - for specific information
about what regional network data is available from IRIS. An NCEDC
version of SeismiQuery is also available.
