Spatiotemporal evolution of tremor activity near the Nankai Trough trench axis inferred from the spatial distribution of seismic amplitudes
Autor: Masashi Ogiso, Koji Tamaribuchi
Publikováno v: Earth, Planets and Space, Vol 74, Iss 1, Pp 1-14 (2022)
Abstract Slow earthquakes have gained importance due to their proximity to the focal regions of megathrust earthquakes. Among slow earthquakes, tectonic tremors have the highest dominant frequency and are thus best resolved. Here, we estimated the lo

Estimation of relative source locations from seismic amplitude: application to earthquakes and tremors at Meakandake volcano, eastern Hokkaido, Japan
Autor: Masashi Ogiso, Kiyoshi Yomogida
Publikováno v: Earth, Planets and Space, Vol 73, Iss 1, Pp 1-14 (2021)
Abstract Although seismic amplitudes can be used to estimate event locations for volcanic tremors and other seismic events with unclear phase arrival times, the precision of such estimates is strongly affected by site amplification factors. Therefore

Ocean-Wave Gradiometry: Visualizing and Extracting Propagation Features of the 15 January 2022 Tsunami Wavefield with Dense Ocean-Bottom Pressure Gauge Arrays
Autor: Masashi Ogiso, Hiroaki Tsushima
Publikováno v: Seismological Research Letters. 94:626-636
Dense geophysical observation networks have recently enabled monitoring the wavefield of sea-bottom pressure changes. Significant sea-bottom pressure disturbances were recorded by ocean-bottom pressure gauge (OBPG) arrays around Japan on 15 January 2
