The EarthScope Primary Instrument Center (EPIC, formerly the PASSCAL Instrument Center) is a research center at New Mexico Institute of Mining and Technology for geophysics research in Earth system science.[1] The facility provides instrumentation and support services for seismology experiments around the world, as well as those for the National Science Foundation and the U.S. Department of Energy.[2]
It supports the research of the Geodetic Facility for the Advancement of Geoscience (GAGE) and the Seismological Facility for the Advancement of Geoscience (SAGE), two National Science Foundation (NSF) organizations.
It was originally the Program for Array Seismic Studies of the Continental Lithosphere (PASSCAL) instrument center, an IRIS (Incorporated Research Institutions for Seismology) facility program dedicated to seismographic data collection associated with research deployments using highly portable seismology instrumentation.[3]
