History-dependent friction and slow slip from time-dependent microscopic junction laws studied in a statistical framework [PDF]
To study the microscopic origins of friction, we build a framework to describe the collective behaviour of a large number of individual micro-junctions forming a macroscopic frictional interface. Each micro-junction can switch in time between two states:

Maximum size and magnitude of injection-induced slow slip events. [PDF]
Fluid injections can induce aseismic slip, resulting in stress changes that may propagate faster than pore pressure diffusion, potentially triggering seismicity at substantial distances from injection wells. Constraining the maximum extent of these aseismic ruptures is, thus, important for better delineating the influence zone of injections concerning ...

Laboratory observations of slow earthquakes and the spectrum of tectonic fault slip modes [PDF]
Slow earthquakes represent an important conundrum in earthquake physics. While regular earthquakes are catastrophic events with rupture velocities governed by elastic wave speed, the processes that underlie slow fault slip phenomena, including recent ...

Identifying slow slip events with satellites [PDF]
Slow slip events (SSEs), in which tectonic plate interfaces slip slowly and generate seismic rumbling, have been observed in many subduction zones around the world. These events can provide insight into the accumulation and release of seismic stress, potentially giving scientists information on the processes generating megathrust quakes.

We stacked daily Global Navigation Satellite System (GNSS) displacement increments in southwest Japan to detect the cumulative crustal deformation accompanying non-volcanic low-frequency tremors from April 1, 2004 to December 31, 2009, which are ...

Depth-varying rupture properties of subduction zone megathrust faults [PDF]
Subduction zone plate boundary megathrust faults accommodate relative plate motions with spatially varying sliding behavior. The 2004 Sumatra-Andaman (M_w 9.2), 2010 Chile (Mw 8.8), and 2011 Tohoku (M_w 9.0) great earthquakes had similar depth variations

On the evolution of elastic properties during laboratory stick-slip experiments spanning the transition from slow slip to dynamic rupture [PDF]
The physical mechanisms governing slow earthquakes remain unknown, as does the relationship between slow and regular earthquakes. To investigate the mechanism(s) of slow earthquakes and related quasi-dynamic modes of fault slip we performed laboratory ...

Nonvolcanic tremor observed in the Mexican subduction zone [PDF]
Nonvolcanic tremor (NVT) activity is revealed as episodes of higher spectral amplitude at 1–8 Hz in daily spectrograms from the continuous seismological records in Guerrero, Mexico.

Paleogeodetic records of seismic and aseismic subduction from central Sumatran microatolls, Indonesia [PDF]
We utilize coral microatolls in western Sumatra to document vertical deformation associated with subduction. Microatolls are very sensitive to fluctuations in sea level and thus act as natural tide gauges.

A window into the complexity of the dynamic rupture of the 2011 Mw 9 Tohoku-Oki earthquake [PDF]
The 2011 Mw 9 Tohoku-Oki earthquake, recorded by over 1000 near-field stations and multiple large-aperture arrays, is by far the best recorded earthquake in the history of seismology and provides unique opportunities to address fundamental issues in ...
