Reports on Geodetic Measurements of Crustal Movement 1906-71.

1973, ca. 400 Seiten mit einigen Bildern. Gebunden Leinen.

This publication consists of reprints of Special Publications, scientific papers and reports as well as copies of correspondence, memoranda, and previously unpublished reports all of which relate to the work of the U.S. Coast and Geodetic Survey in the use of geodetic techniques for monitoring movement of the earth's crust. This collection of papers, which are either out of print or not readily accessible, was assembled in response to suggestions which had been received from geophysists engaged in research in geodynamics. Quoting from the text of the Proposed U.S. Program for the Geodynamics Project (in press), Virtually everything we know about the nature of strain build-up that leads to earthquakes in the western United States comes from geodetic studies that began in the late 1800's." The various items in this publication are arranged chronologically beginning with the report on the San Francisco earthquake of 1906 and ending with the U.S. report to the International Union of Geodesy and Geophysics in 1971 on the crustal movement program in this country ... Memoranda reports (reproduced upon request) are available for the special fault crossing sites established in 196465 and resurveyed periodically since then in connection with the studies along the California Aqueduct. See Figure 1 in Paper No. 65. The appendices contain lists of the major projects and specific areas which have been resurveyed periodically. The dates of the original surveys and subsequent resurveys are shown along with cross references to the numbered reports in this publication or to other sources which are accessible. The task of selecting and collecting the material for this publication was started in 1971 by Charles A. Whitten, Chief Geodesist, National Geodetic Survey. Although Mr. Whitten retired in April 1972 he has continued to give guidance and assistance in the final stages of the work.".
