Static Source Properties of Slow and Fast Earthquakes [PDF]

Journal of Geophysical Research: Solid Earth, 2020
AbstractThe source characteristics of slow and fast earthquakes provide a window into the mechanical properties of faults. In particular, the average stress drop controls the evolution of friction, fault slip, and event magnitude. However, this important source property is typically inferred from the analysis of seismic waves and is subject to many ...

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

Earth, 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

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

Nature 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

Nature 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 ...

A Repeating Earthquake Catalog From 2003 to 2020 for the Raukumara Peninsula, Northern Hikurangi Subduction Margin, New Zealand

Geochemistry, Geophysics, Geosystems, 2021
Repeating earthquakes provide a novel way of monitoring how stresses load faults between large earthquakes. To date, however, and despite the availability of long‐duration, high‐quality seismological datasets, little attention has been paid to tectonic ...

Inter‐episodic Tremor and Slip Event Episodes of Quasi‐spatiotemporally Discrete Tremor and Very Low Frequency Earthquakes in Cascadia Suggestive of a Connective Underlying, Heterogeneous Process

Geophysical Research Letters, 2020
Exploring relationships between different types of slow earthquakes is essential for determining their source properties and controlling parameters. Studies show that very low frequency earthquakes (VLFEs) and tremor are discrete events that necessitate ...

The High‐Frequency Signature of Slow and Fast Laboratory Earthquakes

Journal of Geophysical Research: Solid Earth, 2022
AbstractTectonic faults fail through a spectrum of slip modes, ranging from slow aseismic creep to rapid slip during earthquakes. Understanding the seismic radiation emitted during these slip modes is key for advancing earthquake science and earthquake hazard assessment.

Strain waves, earthquakes, slow earthquakes, and afterslip in the framework of the Frenkel-Kontorova model [PDF]

Physical Review E, 2009
The one-dimensional Frenkel-Kontorova (FK) model, well known from the theory of dislocations in crystal materials, is applied to the simulation of the process of nonelastic stress propagation along transform faults. Dynamic parameters of plate boundary earthquakes as well as slow earthquakes and afterslip are quantitatively described, including ...

Subdaily Slow Fault Slip Dynamics Captured by Low‐Frequency Earthquakes

AGU Advances, 2023
Geodetic positioning is the geophysical record of reference for slow slip events, but typical daily solutions limit studies of the evolution of slow slip to its long‐term dynamics.

Evidence of Localized Failure Along Altered Basaltic Blocks in Tectonic Mélange at the Updip Limit of the Seismogenic Zone: Implications for the Shallow Slow Earthquake Source

Geochemistry, Geophysics, Geosystems, 2020
Field studies have led to several interpretations on the mechanics behind slow earthquake phenomena downdip of the seismogenic zone. To date, field studies have not examined the shallow subduction interface which may also host slow earthquake phenomena ...
