A specific federal plan for the issuance of earthquake predictions and warnings has been proposed for consideration by federal, state, and local agencies. It was outlined by V. E. McKelvey, Director of the U.S. Geological Survey (USGS), on November 7, 1975, at a conference on earthquake warning andresponse in San Francisco, California. Although presently, no operational capability for reliable earthquake prediction exists, it can be expected to be developed soon because of the rapid progress that scientists in the United States, the Soviet Union, Japan, and China are making in earthquake research. Therefore it is not premature to present a tentative plan for issuing predictions and warnings. The plan is expected to change as suggestions for improvements and comments are received, more progress is made in prediction research, and experience in issuing predictions is gained.
