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: 10.1002/2016jb013722
Abstract: Magmatic intrusions release extensional strain in the Earth's crust upon availability of magma. Intrusions are typically accompanied by earthquake swarms and by surface faulting that is often larger than what is expected from the magnitude… read more here.

DOI: 10.1002/2016jb013914
Abstract: We investigated spatiotemporal change in the interplate seismic activity following the 2011 Tohoku-oki earthquake (M9.0) in the region where interseismic interplate coupling was relatively weak and large postseismic slip was observed. We classified earthquakes by… read more here.

DOI: 10.1002/2017gl074455
Abstract: We studied 38 slow slip events (SSEs) in 1997-2016 beneath the Iriomote Island, southwestern Ryukyu Arc, Japan, using continuous Global Navigation Satellite System (GNSS) data. These SSEs occur biannually on the same fault patch at… read more here.

DOI: 10.1002/2017gl074939
Abstract: The spontaneous nucleation of accelerating slip along slowly driven frictional interfaces is central to a broad range of geophysical, physical and engineering systems, with particularly far-reaching implications for earthquake physics. A common approach to this… read more here.

The Impact of Frictional Healing on Stick‐Slip Recurrence Interval and Stress Drop: Implications for Earthquake Scaling

DOI: 10.1002/2017jb014476
Abstract: Interseismic frictional healing is an essential process in the seismic cycle. Observations of both natural and laboratory earthquakes demonstrate that the magnitude of stress drop scales with the logarithm of recurrence time, which is a… read more here.
