Pseudo-bending method for three-dimensional seismic ray tracing in a spherical earth with discontinuities

Publikováno v: Geophysical Journal International. 132:339-346

SUMMARY We present a ‘pseudo-bending’ approach to 3-D ray tracing in a spherical earth with discontinuities. This method is based on a three-point perturbation associated with a first-order approximation, while Snell’s law in curvilinear coordi

[1] We have elucidated depth variations in the stress field associated with the 2007 Noto Hanto, Japan, earthquake by stress tensor inversion using high-quality aftershock data obtained by a dense seismic network. Aftershocks that occurred above 4 km

Along-strike variations in short-term slow slip events in the southwest Japan subduction zone

Autor: Hitoshi Hirose, Shutaro Sekine, Kazushige Obara

Publikováno v: Journal of Geophysical Research. 115

[1] Short-term slow slip events accompanied by nonvolcanic deep low-frequency tremors and deep very low frequency earthquakes in southwest Japan were investigated systematically by means of ground tilting studies. The change in tilt usually lasts for

Waveform inversion for D″ structure beneath northern Asia using Hi-net tiltmeter data

Autor: Robert J. Geller, Kenji Kawai, Shutaro Sekine, Nobuaki Fuji

Publikováno v: Geophysical Research Letters. 36

[1] We invert shear-wave waveform data for the radial variation of (isotropic) shear-velocity in D″ beneath Northern Asia. We reduce source and receiver effects by using data for intermediate and deep events beneath Italy and Japan recorded respect

Slow earthquakes coincident with episodic tremors and slow slip events

Autor: Yoshihiro Ito, Katsuhiko Shiomi, Shutaro Sekine, Kazushige Obara, Hitoshi Hirose

Publikováno v: Science (New York, N.Y.). 315(5811)

We report on the very-low-frequency earthquakes occurring in the transition zone of the subducting plate interface along the Nankai subduction zone in southwest Japan. Seismic waves generated by very-low-frequency earthquakes with seismic moment magn
