Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 27.

This volume is the second AGU monograph on Studies of East Asian Tectonics and Resources (SEATAR). Like its predecessor, Geophysical Monograph 23, The Tectonic and Geologic Evolution of Southeast Asian Seas and Islands, Geophysical Monograph 27 is primarily an outgrowth of a major international program of cooperative research between earth scientists in the United States and their counterparts in Southeast Asia. From a workshop held in Bangkok in October 1973, this research program grew into an international, multimillion dollar program. Most of the U.S. SEATAR research programs were funded by the Office of the International Decade of Ocean Exploration (IDOE) of the National Science Foundation (NSF), but several closely related projects were supported by other sections of the NSF, by the Office of Naval Research, and by others. The formal U.S. SEATAR program is now drawing to a close.
