Near‐continuous tremor and low‐frequency earthquake activities in the Alaska‐Aleutian subduction zone revealed by a mini seismic array [PDF]

, 2017
Tectonic tremor and low-frequency earthquakes (LFEs) are relatively poorly studied in the Alaska-Aleutian subduction zone due to the limited data availability, difficult logistics, and rugged terrain.

Cascadia Slow Earthquake Behaviors Modulated by Tectonic and Environmental Forcings

Geophysical Research Letters
Slow earthquakes, including episodic tremor and slip (ETS), are highly sensitive to small stress perturbations, yet their links to tectonic and non‐tectonic forcings remain unclear.

Preliminary geological evidence for multiple tremors in Kwoi, Central Nigeria

Geoenvironmental Disasters, 2020
Preliminary field assessment of the geological evidence for the September 2016 multiple tremors was felt as far as 10 km in Nok and Chori villages in the north and northwest of Kwoi respectively.

Widespread On‐Fault Geologic Evidence for Variable Mode Coseismic Slip to the Trench in Cascadia

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Investigating the geologic record of near‐trench coseismic strain release is critical for estimating the slip distribution and tsunamigenic potential of future large subduction zone earthquakes. However, the style and extent of upper plate coseismic deformation offshore in subduction zones is poorly constrained.

A Systematic Search for Tectonic Tremor and Low‐Frequency Earthquakes in the Atacama Segment of the Chilean Subduction Zone Turns Up Empty

Subduction megathrusts release stress not only seismically through earthquakes, but also through creep and transient slow deformation, called slow slip events (SSEs).

Denoising Teleseismic Data for Deep Earth Studies Using a Supervised Deep‐Learning Auto‐Encoder: A Case Study of Diffracted Waves From ULVZs

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Seismic noise, particularly the microseism generated by the oceans, is a fundamental limitation on using short period (1–10 s) teleseismic data to study the deep Earth. Deep learning auto‐encoders have proven effective at denoising seismic data in other applications. Here, we provide a demonstration of their potential for improving the quality

Dynamics of the 2022 Unrest Episode of Ruapehu Volcano Revealed by Evolving Tremor Activity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Understanding volcanic unrest episodes and determining whether they will escalate to hazardous eruptions is a key research goal for improving volcano monitoring procedures. Ruapehu volcano, one of the most active in Aotearoa New Zealand, underwent a significant period of unrest in 2022 that was characterized by high levels of seismic tremor ...

Analysis of tremor at the San Andreas Fault at Parkfield [PDF]

, 2013
Emergent phase arrivals, low amplitude waveforms, and variable event durations make detection and location of tectonic tremor a non-trivial task. In this work I employ a new method to identify tremor in large datasets using a semi-automated technique ...

Detection of small crustal deformation caused by slow slip events in southwest Japan using GNSS and tremor data

Earth, Planets and Space, 2019
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 ...

Rock Burst Mechanism under Coupling Action of Working Face Square and Regional Tectonic Stress

Shock and Vibration, 2021
With the development of faults in many coalfields, many large faults will form a relatively independent area, forming regional tectonic stress concentration.
