...MORIAKI YASUHARA Abstract In this study, published Holocene ostracod data for Osaka, Hiroshima, and Iyo-nada Bays within the Seto Inland Sea (SIS), Japan, are re-examined. Five major faunal changes are recognized at different stratigraphic horizons (Horizons 1–5) in the Holocene sedimentary record...

... acceleration values in the range of , and the tilt motion is easily detectable in broadband velocity seismograms ( Zahradník and Plešinger, 2005 ; Kinoshita, 2008 ). Strong-motion observation using velocity seismometers in Japan has expanded with the development of the Muramatsu-type velocity...

The estimated coherence is characterized...

The transverse component velocity waves of surface...

...–Streckeisen STS-2 and Guralp CMG-3T, has increased in the field of earthquake observation. Although the broadband seismometers are primarily oriented toward obtaining far-field records, they have come into use in the field of strong-motion observations. For example, the nationwide broadband network in Japan...

... stations in the Kanto region, Japan. Estimated values of 1/ Q P ( f ) and 1/ Q S ( f ) decrease linearly with increasing frequency at low frequencies. This frequency dependence weakens with increasing frequency. The frequency points at which these two characteristics intersect are approximately 4 and 2 Hz...

...K. Yoshimoto; U. Wegler; M. Korn Abstract We investigated the spatial distribution of S -coda-wave energy in northeastern Honshu, Japan, where a volcanic front runs from north to south. Seismograms of a local event with a magnitude of 6.4 recorded by the Hi-net were analyzed in this study. The mean...

The recently deployed strong-motion seismograph network in Yokohama, Japan, gives a good opportunity to test the H...
