2 images. California Institute of Technology's seismic tape recorder...Turns temblor energy into sound, 21 November 1951. Doctor Hugo Benioff, In Charge of Instrumentation for the Seismographic Laboratory.; Supplementary material reads: "Memo: 1951-11-20. Captions for earthquake story for Thanksgiving. Picture A shows Dr. Hugo Benioff, in charge of instrumentation for the seismo lab, operating the tape recorder, which transforms vibratory movement of earth into small amount of electrical power. Picture B shows tape being run through a playback mechanism which magnifies seismic waves 600 times so they can be heard".本数据集包含2张图像，相关设备为加州理工学院（California Institute of Technology）的地震磁带记录仪（seismic tape recorder），该设备可将地震能量转化为声音信号，图像拍摄于1951年11月21日。雨果·贝尼奥夫（Hugo Benioff）博士时任地震实验室（Seismographic Laboratory）仪器主管。补充材料标注如下：“备忘：1951年11月20日。感恩节地震专题报道配图说明。图A展示了时任地震实验室仪器主管的雨果·贝尼奥夫博士正在操作该磁带记录仪，该设备可将地球的振动转化为少量电能。图B展示了磁带正通过回放装置，该装置可将地震波（seismic waves）放大600倍，以便人类收听。”
