Earthquake Size Distribution: Power-Law with Exponent Beta = 1/2? [PDF]

, 2010
We propose that the widely observed and universal Gutenberg-Richter relation is a mathematical consequence of the critical branching nature of earthquake process in a brittle fracture environment.

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

Earth, 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).

Southern Cascadia episodic slow earthquakes [PDF]

Geophysical Research Letters, 2004
Continuous GPS and seismic data from northern California show that slow earthquakes periodically rupture the Gorda‐North America plate interface within southern Cascadia. On average, these creep events have occurred every 10.9 ± 1.2 months since at least 1998.

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 ...

Long-range, critical-point dynamics in oil field flow rate data [PDF]

, 2006
Earthquake triggering data exhibit long-range spatio-temporal correlations of the power-law form C(l) ∼ l−α and anomalously-slow temporal diffusion of the mean triggering distance of the form: 〈l〉 ∼ tH, with H < 0.5.

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

, 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

Characteristics of Slow Slip Event in March 2020 Revealed From Borehole and DONET Observatories

Frontiers in Earth Science, 2021
We have detected an event of pore pressure change (hereafter, we refer it to “pore pressure event”) from borehole stations in real time in March 2020, owing to the network developed by connecting three borehole stations to the Dense Oceanfloor Network ...

Assessing infrequent large earthquakes using geomorphology and geodesy in the Malawi Rift [PDF]

, 2015
In regions with large, mature fault systems, a characteristic earthquake model may be more appropriate for modelling earthquake occurrence than extrapolating from a short history of small, instrumentally observed earthquakes using the Gutenberg–Richter ...

Frictional Mechanics of Slow Earthquakes [PDF]

Journal 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.
