An Early Forecast of Long‐Period Ground Motions of Large Earthquakes Based on Deep Learning
Autor: Takashi Furumura, Yusuke Oishi
Publikováno v: Geophysical Research Letters, Vol 50, Iss 6, Pp n/a-n/a (2023)
Abstract Long‐period (LP; approximately 2–10 s) ground motions generated by large earthquakes are amplified in large basins and threaten high‐rise buildings in modern cities. In this study, we accomplished an early forecast of LP ground motions

OpenSWPC: an open-source integrated parallel simulation code for modeling seismic wave propagation in 3D heterogeneous viscoelastic media
Autor: Takuto Maeda, Shunsuke Takemura, Takashi Furumura
Publikováno v: Earth, Planets and Space, Vol 69, Iss 1, Pp 1-20 (2017)
Abstract We have developed an open-source software package, Open-source Seismic Wave Propagation Code (OpenSWPC), for parallel numerical simulations of seismic wave propagation in 3D and 2D (P-SV and SH) viscoelastic media based on the finite differe

Distinctive seismic reflections from the subducting Pacific slab for earthquakes in the Ryukyu arc
Autor: Takashi Furumura, Brian L N Kennett
Publikováno v: Geophysical Journal International. 233:1213-1228
SUMMARY During moderate to deep (35–260 km) earthquakes within the Philippine-sea slab along the Ryukyu arc, distinctive later phases after S are observed across the Japanese archipelago for epicentral distances from 1500 to 2200 km, producing anom

High-resolution source imaging based on time-reversal wave propagation simulations using assimilated dense seismic records
Autor: Takashi Furumura, Takuto Maeda
Publikováno v: Geophysical Journal International. 225:140-157
SUMMARY This paper describes an efficient approach to high-resolution time-reversal source imaging simulation. Dense seismograph network records are backpropagated from stations to the hypocentre through a 3-D subsurface structure model to estimate t

Propagation of distinct Love-wave pulses from regional to teleseismic distances in continental and oceanic environments
Autor: Brian Kennett, Takashi Furumura
Publikováno v: Geophysical Journal International. 221:665-682
SUMMARYSurface waves are usually dispersive with long wave trains and steady decay of amplitude with distance. However, if the group velocity is nearly constant for a span of periods a strong pulse is produced that retains its amplitude for large dis

Publikováno v: Nature Communications
Nature Communications, Vol 12, Iss 1, Pp 1-10 (2021)
Rapid and accurate hazard forecasting is important for prompt evacuations and reducing casualties during natural disasters. In the decade since the 2011 Tohoku tsunami, various tsunami forecasting methods using real-time data have been proposed. Howe
