Progress Report, Seismological Laboratory of the California Institute of Technology, 1957

Abstract

On July 1, 1957 Beno Gutenberg retired as Director of the Seismological Laboratory and was succeeded by Frank Press. Beno Gutenberg remains a member of the staff. On February 5, 1958, Harry 0. Wood, who founded the Seismological Laboratory, passed away after a long illness.The long‐standing condition of overcrowding it the Seismological Laboratory was corrected by the acquisition of an adjacent property. The new quarters, known as the Donnelley Laboratory, house offices for staff, visitors, and students as well as a library, map room, seismogram analysis room, and ultrasonic seismic model laboratory. An important feature of the Donnelley Laboratory is a tunnel 150 ft long, located in granite at a depth of 60 ft beneath the building. A linear strain seismograph and ultra long‐period pendulums will be installed in the tunnel. The old quarters are being extensively remodeled and will be known as the Kresge Laboratory, housing the main seismograph vaults and recording rooms, experimental piers, electronics laboratory, machine shop, storage and stock rooms, photographic dark room, and offices for technicians.
