Earthquake prediction studies in Southern California: Research in progress, June 1976

Abstract

The report of an uplift of the ground of up to 0.25 meters over at least 12,000 square kilometers of southern California (Castle, Church, and Elliott, 1976, Science, 192, pages 251-253) has increased significantly the interest in earthquake prediction studies in this region. A substantial increase in research is planned, particularly by the U.S. Geological Survey and its many contractors and by the California Division of Mines. The purpose of this report is to briefly summarize most of the work in progress to encourage communication among the wide variety of researchers and to assist all present or prospective researchers in this region to understand what work is underway and not yet published. Information in this report was collected primarily in response to a brief questionnaire. Some researchers did not respond and some may not have received copies of the questionnaire. Thus this report is not complete but we believe it summarizes the vast majority of research in progress. Any additions or corrections should be sent to the editor. The first name listed under each project is the person doing the most work on the project. The principal investigator, when not the first person on the list of names, is denoted by an asterick. Funding for the research listed comes primarily from the U.S. Geological Survey, National Science Foundation, and the State of California.
