Charge of the Advisory Committee on PASSCAL Active Seismic Sources
The Incorporated Research Institutes for Seismology (IRIS) currently provides seismic recording instruments to the academic and government seismology research community. Although much of the community’s seismology research is carried out in a “passive” mode of operation, in which researchers are recording seismic signals from natural or ambient seismic sources, a subset of the IRIS community relies on “active” seismic sources in which the researchers generate seismic signals using a variety of mechanical and chemical sources.
