The Incorporated Research Institutions for Seismology (IRIS) Consortium has produced an ambitious plan for new seismological research facilities to be developed during the coming decade. The plan reflects a broad consensus among seismologists in this country with respect to both the need for improved data and the potential for significant scientific advances that can occur as a result. The three elements of this program are a 100-station broadband global network utilizing satellite telemetry, a 1000-station portable network of advanced digital seismographs, and a national center for management and distribution of the data generated by these networks to the research community. The purpose of this paper is to provide a brief overview of the long-range plan and an update as to the progress made to date.
