Slip bursts during coalescence of slow slip events in Cascadia
Nature Communications, 2020 Slow slip events are commonly observed on natural faults all around the world and are suggested to precede large magnitude and/or high frequency earthquakes.

Tectonic Tremor Explained by Successive Ruptures of Clustered Quartz‐Filled Shear Veins
Geophysical Research LettersA tectonic tremor is a successive seismic signal observed along plate boundaries in subduction zones. However, the source processes and mechanisms responsible for the tremor remain unclear. Quartz‐filled shear and extension veins are clustered in tens to

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
Deep Underground Science and Engineering, EarlyView.A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Characteristics of Seismic Energy Rate Functions of Shallow Tremors
Geophysical Research LettersWe investigated the energy rate functions of shallow tremors southeast of the Kii Peninsula in the Nankai subduction zone. Unimodal functions (triangle or bell‐shaped) explain the characteristics of small (

Unraveling the Origin of Slow Earthquakes
Eos, 2019 Different nucleation styles detected in five slow-slip events in the same area of Japan’s Ryukyu subduction zone suggest the physical properties along this tectonic plate interface change over time.
