  1. 13:30-13:45
    TITLE: Groundwaters and deep-seated fluid circulation around Aso Volcano, Southwest Japan, revealed by multivariate statistical analysis of the geochemical data
    AUTHOR: *Hikaru IWAMORI, Hitomi NAKAMURA・Noritoshi MORIKAWA・Masaaki TAKAHASHI・Akihiko INAMURA (AIST), Satoru HARAGUCHI, Tatsuji NISHIZAWA (Mt. Fuji Res. Inst.) and Shuhei SAKATA
    SUMMARY: Groundwater geochemistry and its statistical analyses revealed how fluids of shallow and deep origins cycle in Aso Volcano and from a subducted slab beneath central Kyushu.
  2. 13:45-14:00
    TITLE: Extraction of P-S converted waves from teleseismic P-wave microseisms
    AUTHOR: *Shota KATO and Kiwamu NISHIDA
    SUMMARY: We developed the source deconvolution method to extract P-S waves converted beneath receivers from teleseismic P-wave microseisms.
  3. 14:00-14:15
    TITLE: Single-station seismic event classification based on a modified deep embedded clustering architecture and its application to Harrison County, Eastern Ohio
    AUTHOR: *Jeffrey CHURCH, Dongdong YAO (China University of Geosciences), Yihe HUANG (University of Michigan) and Zefeng LI (University of Science and Technology of China)
    SUMMARY: We recast the problem of classifying tectonic and anthropogenic waveforms as a clustering problem, thereby avoiding the labor of creating a large labeled dataset.
