Benioff Vertical Seismometer (WWSSN)

Description
This is a variable reluctance, short-period vertical seismometer based on the design of Hugo Benioff, a scientist on the staff of the Seismological Laboratory at the California Institute of Technology in Pasadena. It was made by The Geotechnical Corporation in Dallas, Texas, in the early 1960s, for use in VELA-Uniform, a government-sponsored project designed to detect and map earthquakes and underground nuclear explosions. One part of VELA-Uniform was a World Wide Standardized Seismograph Network.
This example marked "Model No. 1051 / Serial No. 210" was used at the WWSSN station at Junction City, Texas.
