[SSS10-P08] Sonification of Seismograms for Exploring Dynamic Triggering Earthquakes
Keywords:Seismic Sonification, Dynamic Triggering Earthquakes
Here we are going to apply the sonification technique to the exploration of the dynamic triggering event without any bandpass or highpass filters. At least, this will be useful for the screening. For that purpose, we are developing the software named as Sonification of Seismograms (SoS) to perform the sonification. The sonification technique assigns sounds according to the dominant frequency and the amplitude of the moving time window (Matsubara et al., 2016). The dominant frequency was defined as the number of zero-crossing divided by the length of the time window. The program operates on SuperCollider. By a GUI, we can choose the area where the stations are used for the sonification.
We sonified seismograms for earthquakes greater than M 7 in the world. In front of our poster, we will provide the opportunity to listen the sonified sounds for the seismograms with and without dynamic triggering events.
We used the Global CMT Catalog and seismic data from Hi-net of NIED, seismic data from JMA, Hokkaido University, Hirosaki University, Tohoku University, the University of Tokyo, Nagoya University, Kyoto University, Kochi University, Kyushu University, Kagoshima University, and AIST. This work was supported by JSPS KAKENHI 17K14386.
