The development of earthquake seismology in the western United States
Published:January 01, 1985
This paper traces the growth of seismology in the western United States, giving emphasis to geological connections. Pre-instrumental foundations of a science of earthquakes were laid late last century by geologists, especially G. K. Gilbert. These early studies were based largely on Quaternary tectonic structural features evident in the west. The 1906 San Francisco earthquake resulted in a tremendous increase in seismological research and knowledge, including H. F. Reid’s “elastic rebound” fault theory of the seismic source, theses on seismic hazards, prediction, seismometry, and other related topics. Significant growth of seismographic networks in California under the auspices of the University of California, Berkeley, and the California Institute of Technology, led to many geologically valuable results on such issues as seismic activity, tectonic patterns, and focal mechanisms. This discussion covers the period up to about 1960.

Geologists and Ideas
An unusually coherent, well-written volume. Prepared for DNAG by the History of Geology Division of GSA. Spotlights events, ideas, and people, and sheds light on the history of North American geology as a whole. With its many intellectual jewels on the evolution of scientific concepts, this book will provide many happy hours of entertainment and instruction for anyone interested in the history of science, especially that of the earth sciences. Thirty-four papers are organized into four categories: (1) The Evolution of Significant Ideas; (2) Contributions of Individuals; (3) Contributions of Organized Groups; and (4) Application of Significant Ideas. Excellent as a course-book or for additional reading for classes related to the history of geology or general science.
