本研究は、地殻変動観測と理論・実験的考察を組み合わせることによって、活火山におけるダイク貫入停止のメカニズムについて考察した。ダイク貫入停止メカニズムについては以下の4つのメカニズムを考察した。(1) マグマの冷却による固化、(2) 貫入ダイクの体積不足、(3) マグマに働く負の浮力、(4) ダイク先端付近の応力擾乱。さらに、1997年・1998年伊豆半島東方沖群発地震および2015年桜島噴火未遂を例にとって、ダイク貫入停止のメカニズムを考察した。その結果、伊豆半島のケースについては貫入マグマの… もっと読む

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
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
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
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
