Earthquakes occur by overcoming fault friction; therefore, quantifying fault resistance is
central to earthquake physics. Values for both static and dynamic friction are required, and …

It has long been recognized that sediments subducting along the megathrust influence the
occurrence of giant (M w≥ 8.5) megathrust earthquakes. However, the limited observation …

Undulating topography on a subducting oceanic plate causes substantial deformation of the
accretionary wedge. In particular, the subduction of a seamount is considered to induce 1) …

We report thermal conductivities, thermal diffusivities, and volumetric heat capacities
determined by a transient plane heat source method for four whole-round core samples …

The temperature response to stress changes of rocks is key to understanding temperature
anomalies in geoscience phenomena such as earthquakes. We developed a new …

Abstract The March 2011 M w 9.0 Tohoku-Oki earthquake activated shallow aftershocks with
normal faulting focal mechanisms near the trench axis. To investigate stress state in the …

We determine the trace element stratigraphy of Site C0019, drilled during the Japan Fast
Trench Drilling Project (JFAST) International Ocean Discovery Program (IODP) Expedition …

Temperature is widely believed to act as a primary control on fault rheology, and therefore
on the distribution of seismicity along plate boundary faults. However, there are few detailed …

Abstract On December 7, 2012, a pair of large Mw 7.2 intraplate earthquakes occurred near
the Japan Trench axis off Miyagi, northeast Japan. This doublet consisted of a deep reverse …

Understanding slip behavior of active fault is a fundamental problem in earthquake
investigations. Well logs and cores data provide direct information of physical properties of …
