Three-dimensional resistivity structure in the Nankai Trough off Kumano inferred using marine magnetotelluric investigations

Earth, Planets and Space
Megathrust and slow earthquakes are known to occur in the area off Kumano, along the eastern part of the Nankai Trough, Japan. Pore fluids along the fault surface play an important role in earthquake occurrence, but the detailed fluid distribution ...

Investigation on short-term slow slip events in the northeast Japan subduction zones using decadal GNSS data

Earth, Planets and Space
Since their discovery over 25 years ago, slow slip events (SSEs) have been regarded as key phenomena for better understanding the characteristics and kinematics of faults.

Temporal variation in seismic moment release rate of slow slips inferred from deep low-frequency tremors in the Nankai subduction zone

Earth, Planets and Space, 2020
We examined seismic moment release rates as estimated from deep low-frequency tremors at episodic tremor and slip (ETS) zones on the plate interface in the Nankai subduction zone.

The Possible Observation of Slow Slip Events Prior to the Occurrence of the 1999 Chi-Chi Earthquake

Terrestrial, Atmospheric and Oceanic Sciences, 2012
Possible short-term precursors several days before the Taiwan Chi-Chi earthquake (Mw = 7.6) on 20 September 1999 were observed by examining crustal deformation that were directly integrated from broadband velocity seismograms.

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 Letters
A 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

The 2016 Mw 5.9 earthquake off the southeastern coast of Mie Prefecture as an indicator of preparatory processes of the next Nankai Trough megathrust earthquake

Progress in Earth and Planetary Science, 2018
Megathrust earthquakes have occurred repeatedly at intervals of 100 to 150 years along the Nankai Trough, situated in the southwest of Japan. Given that it has been 70 years since the last event, the occurrence of the next devastating earthquake is ...

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.

Spatiotemporal Characteristics of Tectonic Tremors in California

Geophysical Research Letters
California, as a transform plate boundary, provides a distinctive tectonic setting and an ideal natural laboratory for investigating tectonic tremors and the slow deformation associated with plate motion.
