...Carnegie Institution's seismograph station on Mt. Wilson in California, Dr. Hugo Benioff has built recorders which work by electromagnetism. The weight is a magnet hung so that its poles are a tiny fraction of an inch from the armature. When an earth tremor twitches the armature, the distance between it and the magnet changes slightly, altering the magnetic field and creating a tiny electric current which is amplified by vacuum tubes. This current fluctuates the light beam which makes the record, also twitches a galvanometer needle. In the Benioff seismograph, earth movements are magnified 200,000 times...
