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.

- 01 Jan 2013
TL;DR: In this article, the authors describe the practice in the analysis and interpretation of noble gases in modern hydrothermal systems, including sample collection and analytical methods, implications of geographical distribution of helium isotopes in the large scale (100-1000 km) and the small scale (1-100 km), temporal variation of the helium isotope in some volcanoes, and the other noble gas isotope and abundance variations in hydro thermal systems.

Seismic and geodetic constraints on Cascadia slow slip
TL;DR: In this article, the authors detect and locate tremor epicenters from episodic tremor and slip (ETS) episodes in northern Cascadia providing a high-resolution map of Washington's slow slip region.
Slow slip predictions based on granite and gabbro friction data compared to GPS measurements in northern Cascadia
Yajing Liu,James R. Rice +1 more
TL;DR: This article applied the laboratory rate and state friction data of granite and gabbro gouges under hydrothermal conditions to a Cascadia-like 2D model to produce spontaneous aseismic transients.
The 2006 slow slip event and nonvolcanic tremor in the Mexican subduction zone
Vladimir Kostoglodov,Allen Husker,Nikolai M. Shapiro,J. S. Payero,Michel Campillo,Nathalie Cotte,Robert W. Clayton +6 more
TL;DR: In this article, the authors investigated the relationship between slow slip events and nonvolcanic tremor (NVT) in different subduction zones and continental faults and found that although the NVT energy increased notably during the 2006 SSE, the two phenomena were separated spatially and not completely synchronized in time.
Along-fault pore-pressure evolution during a slow-slip event in Guerrero, Mexico
William B. Frank,Nikolai M. Shapiro,Allen Husker,Vladimir Kostoglodov,Harsha S. Bhat,Michel Campillo +5 more
TL;DR: In this paper, the authors compare two slow earthquake phenomena observed in the Guerrero region of the Mexican subduction zone: low-frequency earthquakes (LFEs) and a slow-slip event (SSE) recorded by GPS.

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.
