Proceedings of the eighth joint meeting of the U.S.-Japan Conference on Natural Resources (UJNR) Panel on Earthquake Prediction Technology, November 16-21, 1992

Abstract

The UJNR Panel on Earthquake Prediction Technology recognizes the critical improtance of promoting prediction research in both countries. The Eigth Joint Meeting was extremely beneficial in furthering friendship and deepening understanding of the common problems of both Japan and the U.S.Technical sessions included presentation of 27 papers, focussing on great subduction zone earthques in Japan and the U.S., including extensive discussion of national and agency programs, probabilistic methods of earthquake forecasting, earthquake precursors, fundamental earthquake studies, crustal structure and the M 7.5 Landers, California earthquake of 1992.Discussion was extremely frutiful, and the Panel unanimously adopted the following resolutions: 1. One of the most important means of achieveing joint progress is by the long-term exchange of researchers between our two countries. Since the First Joint Meeting such exchanges have already achieved extremely valuable results. We recognize the advantages of close coopearation between governmental and academic scientists in earthquake prediction research in both the United States and Japan. Each side should investigate possibilities for widening participation in the Panel. In this respect, the panel members recognize the importance of joint activities in the form of symposia, and support the proposal of cooperative programs on earthquake prediction research under the U.J.S.T. agreement. Efforts should also be made to cooperate on instrumental development, observations, data interpretation, and earthquake prediction experience, collocation between laser ranging, GPS and VLBI techniques, development of transportable VLBI and SLR systems, research on active faults, and laboratory rock mechanics. 2. We strongly agree that exchanges of data and analysis methods are mutually beneficial, and strongly encourage these activities. In particular, the Panel empahasizes the importance of sharing experience and exchanging data in the areas of geodetic measurements, crustal deformation and monitoring, precursory phenomena, modelling techniques, and automatic processing of both seismic and crustal deformation data. 3. Advances in the archiving and retrieval of seismic waveform data has created a new envornment for collaborative research. The panel endorses and encourages cooperation in the analysis of these data, and recognizes the potential for exchange of these data through computer network connections between our two countries. 4. Cooperation in the application of space techniques to prediction research is already in progress and should continue. Information on the precision geodetic measurements and GPS measurements for the detection of crustal deformation should be exchanged. Cooperative experiments using U.S. and Japanese laser ranging and VLBI facilities should be continued. 5. The next joint meeting will be held in Japan in the autumn of 1994.
