The Second Joint Meeting of the UJNR Panel on Earthquake Prediction Technology was held at the U.S. Geological Survey facilities in Menlo Park, California, during the week of July 13, 1981. This panel, which was established in 1978, is the newest of 17 panels under the United States/Japan Cooperative Program in National Resources (UJNR). The UJNR program is based on a 1964 cabinet-level agreement to foster the exchange of scientists, information, equipment, and knowledge between government agencies in Japan and the United States concerned with problems involving natural resources.
