Earthquakes of the Nepal Himalaya : Towards a Physical Model of the Seismic Cycle [PDF]

open access: yes, 2013
Home to hundreds of millions of souls and land of excessiveness, the Himalaya is also the locus of a unique seismicity whose scope and peculiarities still remain to this day somewhat mysterious.

Frictional Mechanics of Slow Earthquakes [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2018
AbstractTectonic faults slip in a wide range of modes that span from slow slip events to dynamic rupture. A growing body of observations document this spectrum of failure modes in many geologic settings. However, the physical mechanisms that dictate slow slip are not understood.

Slow deformation event between large intraslab earthquakes at the Tonga Trench

open access: yesScientific Reports, 2021
Slow deformations associated with a subducting slab can affect quasi-static displacements and seismicity over a wide range of depths. Here, we analyse the seismotectonic activities in the Tonga subduction zone, which is the world’s most active area with ...

Bridging the gap between low-frequency and very-low-frequency earthquakes

open access: yesEarth, Planets and Space, 2020
Slow earthquakes that are observed in the > 1 Hz frequency band are called tectonic tremor or low-frequency earthquakes (LFEs) and those in the 0.01–0.10 Hz band are called very-low-frequency earthquakes (VLFEs).

The slow self-arresting nature of low-frequency earthquakes

open access: yesNature Communications, 2021
Low-frequency earthquakes are a series of small earthquakes with lower dominant frequencies than ordinary earthquakes. By comparing the simulated earthquakes with the real data, we find that low-frequency earthquakes represent an earthquake rupture ...

Temporal gravity anomalies observed in the Tokai area and a possible relationship with slow slips

open access: yesEarth, Planets and Space, 2018
The water in Earth’s mantle is closely related with plate subduction and volcanism. Recent studies revealed that the mantle wedge corner at approximately 30 km depth holds high-pressure water, where many slow earthquakes occur. To quantify how such water

Data from: Contained Laboratory Earthquakes Ranging From Slow To Fast

open access: yes, 2019
Loading a 3-meter granite slab containing a saw-cut simulated fault, we generated slip events that spontaneously nucleate, propagate, and arrest before reaching the ends of the sample. This work shows that slow (0.07 mm/s slip speeds) and fast (100 mm/s)

Defining the Relationship between Seismicity and Deformation at Regional and Local Scales [PDF]

open access: yes, 2013
In this thesis, I use source inversion methods to improve understanding of crustal deformation along the Nyainquentanglha (NQTL) Detachment in Southern Tibet and the Piceance Basin in northwestern Colorado.

Effects of episodic slow slip on seismicity and stress near a subduction-zone megathrust

open access: yesNature Communications, 2021
Large slow slip earthquakes and tremor occur in subduction zones near the locked megathrust. Combined analysis of changes in slab seismicity and stress field near the times of such slow slip events highlights the role of fluid in promoting slow slip.

The influence of the brittle-ductile transition zone on aftershock and foreshock occurrence

open access: yesNature Communications, 2020
Earth surface continues to slip after large earthquakes at a slow velocity for a period of a year or more. In this study, the authors show how such slow slip before and after large earthquakes relates to the interaction of the brittle zone of the fault ...
