Abstract
A strong-motion earthquake recorder for the direct measurement of one point on the response spectrum curve is described, and results obtained with the instrument under field conditions are compared with those obtained by a standard spectrum analysis of accelerograph records. The device has the advantages of low initial cost and of low maintenance expense, and can thus be installed in relatively large numbers. A network of such instruments located at points having various local geological conditions is proposed as a supplement to the U. S. Coast and Geodetic Survey strong-motion seismograph system.

Copyright © 1961, by the Seismological Society of America. Manuscript received for publication October 24, 1960, and, as revised, January 13, 1961. The design and construction of the prototype seismoscope was carried out by the U. S. Coast and Geodetic Survey under the direction of Elliot B. Roberts, Chief, Division of Geophysics. Numerous contributions were made by various members of the Seismological Field Survey Staff, including Richard P. Maley, John Hershberger, and Charles F. Knudson. C. Martin Duke and David J. Leeds of the University of California at Los Angeles made the required studies on seismoscope location. Many useful suggestions for production of the field model were made by J. J, Wilmot of Wilmot Engraving and Instrument Company. Wilfred D. Iwan of the Division of Engineering, California Institute of Technology, conducted the laboratory tests of the field model. Thanks are expressed to the National Science Foundation for a grant through the Engineering Sciences Division, which was administered for the California Institute of Technology by G. W. Housner and D. E. Hudson.Attached Files
