DOI: 10.1002/2016gl071798
Abstract: We investigated seismic wave velocity in the subducting crust of the Pacific slab beneath eastern Hokkaido, northern Japan. To detect depth-dependent properties of the seismic velocities in the crust, we analyzed guided waves that propagate… read more here.

DOI: 10.1002/2016jb013383
Abstract: The dynamics of magma ascent along volcanic conduits toward the Earth's surface affects eruptive styles and contributes to volcanic hazard. The rheology of ascending magmatic mixtures is known to play a major role on mass… read more here.

DOI: 10.1002/2016jb013676
Abstract: Talc is present in several large-scale fault zones world-wide, and is mineralogically stable at temperature of the upper crust. It is therefore necessary to gain a better understanding of the frictional behavior of talc under… read more here.

DOI: 10.1002/2016jf004133
Abstract: The dynamic response of Greenland tidewater glaciers to oceanic and atmospheric change has varied both spatially and temporally. While some of this variability is likely related to regional climate signals, glacier geometry also appears to… read more here.

DOI: 10.1002/2017gl073106
Abstract: Slow seismic velocity anomalies are commonly imaged beneath subducting slabs in tomographic studies, yet a unifying explanation for their distribution has not been agreed upon. In South America two such anomalies have been imaged associated… read more here.

DOI: 10.1002/2017jb014355
Abstract: The Alpine Fault, a transpressional plate boundary between the Australian and Pacific plates, is known to rupture quasi-periodically with large magnitude earthquakes (Mw ~8). The hydraulic and elastic properties of fault zones are thought to… read more here.
