Waveform inversion for 3-D S-velocity structure discovers possible evidence for a remnant slab and a passive plume

Suzuki et al. (2016) have conducted waveform inversion to infer the three-dimensional (3-D) S-velocity structure in the lowermost 400 km of the mantle (the D'' region) beneath the Northern Pacific region. The 3-D S-velocity model obtained in this stu… もっと読む

Slip-partitioned surface ruptures following the 2016 Mw 7.0 Kumamoto earthquake

Together with geodetic and seismic inversions of subsurface fault slip for the 2016 Mw = 7.0 16 April 2016 Kumamoto earthquake, Toda et al. (2016) present a schematic structural model where oblique motion occurred on a northwest-dipping subsurface fa… もっと読む

Response of hydrothermal system to stress changes

Time-lapse monitoring of seismic velocity at volcanic areas can provide unique insight into the property of hydrothermal and magmatic fluids and their temporal variability. Taira and Brenguier (2016) established a quasi real-time velocity monitoring system by using seismic interferometry with ambient noise to explore the temporal evolution of velocity in the Lassen Volcanic Center, Northern California. もっと読む

Toward the effective geodetic observation network

About 40 tracking stations all over the world are currently operational for Satellite Laser Ranging (SLR), a very precise geodetic technique. Otsubo et al. (2016) ran a unique simulation to find the optimal place of a future SLR station. The answer depends on a geodetic product and one example is shown for the center of gravity of the Earth: the X and Y components are largely improved by a high-latitude station especially in the southern hemisphere, whereas the Z component is improved by a low-latitude station. もっと読む
