Abstract

The year 2004 marked the twentieth anniversary of the Incorporated Research Institutions for Seismology (IRIS) Consortium and its four core programs: the Program for Array Seismic Studies of the Continental Lithosphere (PASSCAL), the Global Seismic Network (GSN), Education and Outreach (E&O),and the Data Management System (DMS).

IRIS activities (www.iris.edu) are supported principally through the U.S. National Science Foundation's (NSF) Earth Sciences Instrumentation and Facilities Program, and through the community efforts of IRIS's more than 150 member institutions in the United States and abroad. The consortium provides fundamental capabilities for the exploration of the Earth's interior through the collection and distribution of seismographic data. PASSCAL is the IRIS facility program dedicated to seismographic data collection associated with temporary deployments using highly portable instrumentation.
