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).

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 ...

Southern Cascadia Episodic Slow Earthquakes [PDF]

open access: yes, 2004
Continuous GPS and seismic data from northern California show that slow earthquakes periodically rupture the Gorda-North America plate interface within southern Cascadia.

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.

The Radiated Energy of the 2004 Sumatra-Andaman Earthquake [PDF]

open access: yes, 2006
We use several independent methods to estimate the radiated energy E_R of the Sumatra-Andaman earthquake (M_w=9.0 to 9.3), and investigate whether the difference in the rupture patterns between north and south is reflected in the difference in the energy

Persistent termini of 2004- and 2005-like ruptures of the Sunda megathrust [PDF]

open access: yes, 2012
To gain insight into the longevity of subduction zone segmentation, we use coral microatolls to examine an 1100-year record of large earthquakes across the boundary of the great 2004 and 2005 Sunda megathrust ruptures.

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 ...

Modeling of residual spheres for subduction zone earthquakes: 1. Apparent slab penetration signatures in the NW Pacific caused by deep diffuse mantle anomalies [PDF]

open access: yes, 1990
We have computed focal residual spheres for 145 subduction zone earthquakes along the northwest edge of the Pacific using regional and global mantle velocity models from tomographic inversions.

Universal Approach to Overcoming Nonstationarity, Unsteadiness and Non-Markovity of Stochastic Processes in Complex Systems [PDF]

open access: yes, 2004
In present paper we suggest a new universal approach to study complex systems by microscopic, mesoscopic and macroscopic methods. We discuss new possibilities of extracting information on nonstationarity, unsteadiness and non-Markovity of discrete ...

Depth-varying rupture properties of subduction zone megathrust faults [PDF]

open access: yes, 2012
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
