UUSS invited to become a formal Member-Institution of the International Seismological Centre (ISC).

The University of Utah Seismograph Stations (UUSS) is excited to announce it was recently invited to become a formal Member-Institution of the International Seismological Centre (ISC).

The ISC is a non-governmental, non-profit international organization which maintains extensive information about earthquakes and other seismic events from around the world. ISC members strive to collect, archive, and process seismic station and network bulletins and prepare and distribute the ISC bulletin – the definitive summary of the world’s seismicity.

Since its inception in the 1960s, the ISC has provided invaluable data used by thousands of seismologists worldwide. The current ISC mission is to maintain the ISC bulletin, the International Seismographic Station Registry, and the IASPEI Reference Event list. ISC also maintains several other important catalogs, contacts, and datasets.

The UUSS is honored to join the ISC. It joins 68 other research and operational organizations in 50 countries that support the ISC. Other ISC Members in the United States include NEIC/USGS, IRIS, and the TexNet of the University of Texas at Austin. The invitation to join comes as a great recognition of the important work of the UUSS on a national, and now international, scale.
