Abstract

One of the most promising areas of international cooperative research in geophysics is broadband seismology. At a recent symposium on this topic (International Symposium on Global Seismology and the POSEIDON (Pacific Orient Seismic Digital Observation Network) Project, University of Tokyo, August 1988) papers were presented by representatives of the United States, Japan, Soviet Union, People's Republic of China, Italy, Federal Republic of Germany, Canada, Netherlands, and Australia. National and international associations of Earth scientists committed to the establishment of a global network of broadband instruments include the U.S. Geological Survey, POSEIDON of Japan; IRIS (Incorporated Research Institutions for Seismology) of the U.S.; GEOSCOPE of France; MEDNET (Mediterranean Network) of Rome, Italy, and Geneva, Switzerland, but comprising many Mediterranean countries; ORFEUS (Observatories and Research Facilities for European Seismology), a working group of the European Geophysical Society; and CANDIS (Canadian Digital Seismic Network). An umbrella organization for all these associations is FDSN, the international Federation of Digital Seismological Networks.
