Nonvolcanic deep tremor associated with subduction in southwest Japan.
TL;DR: Deep long-period tremors were recognized and located in a nonvolcanic region in southwest Japan, indicating that the tremors may have been caused by fluid generated by dehydration processes from the slab.

Abstract: Deep long-period tremors were recognized and located in a nonvolcanic region in southwest Japan. Epicenters of the tremors were distributed along the strike of the subducting Philippine Sea plate over a length of 600 kilometers. The depth of the tremors averaged about 30 kilometers, near the Mohorovic discontinuity. Each tremor lasted for at most a few weeks. The location of the tremors within the subduction zone indicates that the tremors may have been caused by fluid generated by dehydration processes from the slab.

TL;DR: Friction is resistance to motion that appears when two surfaces in contact slide against one another as discussed by the authors , and the concept of friction describes the dissipation of energy that occurs in sliding friction.

TL;DR: In this article , the authors used a version of space-time epidemic-type aftershock sequence (ETAS) model with non-stationary background rate to detect earthquake swarms that may be related to slow slip events (SSEs) in the Nankai region.

TL;DR: In this article, the authors proposed a method to detect and clarify such an evolving process related to the temporal changes that are governed by the structure sensitivity, and may presumably be associated with the movement of the fluid mainly composed of supercritical water in the crust and upper mantle conditions.

Long-period volcano seismicity: its source and use in eruption forecasting
TL;DR: At an active volcano, long-period seismicity reflects pressure fluctuations resulting from unsteady mass transport in the sub-surface plumbing system, and hence provides a glimpse of the internal dynamics of the volcanic edifice as mentioned in this paper.
Volcanic tremor: Nonlinear excitation by fluid flow
TL;DR: In this article, a simple lumped-parameter tremor model involving the flow of an incompressible viscous fluid through a channel with movable elastic walls leads to a third-order system of nonlinear ordinary differential equations.

Complete miscibility between silicate melts and hydrous fluids in the upper mantle: experimental evidence and geochemical implications
Hélène Bureau,Hans Keppler +1 more
TL;DR: The phase relationship between silicate melts and hydrous fluids was studied by direct visual observation in an externally heated diamond-anvil cell as mentioned in this paper, where complete miscibility of silicate melt and water was observed for a wide range of melt compositions, including nepheline, jadeite, dacite, haplogranite and Ca-bearing granite.

Deep, low-frequency microearthquakes in or around seismic low-velocity zones beneath active volcanoes in northeastern Japan
Akira Hasegawa,Akira Yamamoto +1 more
TL;DR: In this paper, precise hypocenter relocations have been made for shallow intraplate microearthquakes beneath northeastern Japan by applying source region station corrections, and the relocated hypocenter distribution shows that most of the events are confined to the upper 15 km of the crust which forms the brittle seismogenic zone in this volcanic arc.
