Earthquakes anywhere in the world show up in Dr. Charles F. Richter's living room on his new home appliance--a seismograph. The Caltech professor of seismology had the instrument installed to facilitate his participation at night in two projects: the exchange of earthquake information with news people and the Seismic Sea Wave Warning Systerm of the U.S. Coast and Geodetic Survey. Dr. Richter is looking at the drum on which the 'quake record is written. At the lower left is the control unit, which amplifies the earthquake signal. Photo dated: May 19, 1963.
