Distributed acoustic sensor (DAS) observes the intensity and phase of Rayleigh backscattered light to measure the strain caused along with an optical fiber cable at intervals of several meters. In this article, we analyzed DAS measurement data performed from November 8 to December 2, 2019, using the dark fiber of the Sanriku offshore optical communication cable for the submarine earthquake and tsunami observation system owned by the Earthquake Research Institute, the University of Tokyo. We report the analysis results of the vibrations occurred by earthquake, waves, and ship. |
