A Global Centroid Catalog of S‐Wave Microseisms: Insights Into the Role of Sedimentary Layers

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Although centroid catalogs of P‐wave microseisms have been established, a corresponding centroid catalog of S‐wave sources has been lacking. In this study, we constructed a centroid catalog of S‐wave microseisms. We generalized the autofocusing method to radial and transverse components to estimate the source locations of SV‐ and SH‐wave ...

Harmaline Tremor: Underlying Mechanisms in a Potential Animal Model of Essential Tremor [PDF]

, 2012
Background: Harmaline and harmine are tremorigenic β-carbolines that, on administration to experimental animals, induce an acute postural and kinetic tremor of axial and truncal musculature.

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes

Geophysical Research Letters
Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress ...

The role of velocity‐neutral creep on the modulation of tectonic tremor activity by periodic loading [PDF]

Geophysical Research Letters, 2012
Slow slip events and associated non‐volcanic tremors are sensitive to oscillatory stress perturbations, such as those induced by tides or seismic surface waves. Slow slip events and tremors are thought to occur near the seismic‐aseismic transition regions of active faults, where the differencea − b = ∂μ/∂lnVbetween the sensitivity of friction to slip ...

Probing Slow Earthquakes With Deep Learning

Geophysical Research Letters, 2020
Slow earthquakes may trigger failure on neighboring locked faults that are stressed sufficiently to break, and slow slip patterns may evolve before a nearby great earthquake.

Episodic Seismicity Bursts Driven by Magma Intrusion During the 2025 Santorini‐Amorgos Seismic Crisis

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The 2025 Santorini–Amorgos seismic crisis in Greece had an exceptionally large number and sustained rate of moderate‐sized earthquakes. We used a machine‐learning‐based earthquake monitoring workflow to detect and relocate 66,109 earthquakes and interpret the results in the context of global analogs.

A Multi‐Region Deep Learning Framework for Low‐Frequency Earthquake Detection: Application to the Guerrero Seismic Gap

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Low‐frequency earthquakes (LFEs) provide key constraints on slow earthquake processes but remain difficult to detect because of their low signal‐to‐noise ratios (SNR) and emergent onsets, particularly in offshore environments where seismic networks are sparse.

Tectonic Tremor Explained by Successive Ruptures of Clustered Quartz‐Filled Shear Veins

Geophysical Research Letters
A tectonic tremor is a successive seismic signal observed along plate boundaries in subduction zones. However, the source processes and mechanisms responsible for the tremor remain unclear. Quartz‐filled shear and extension veins are clustered in tens to

Llaima volcano dataset: In-depth comparison of deep artificial neural network architectures on seismic events classification

Data in Brief, 2020
This data manuscript presents a set of signals collected from the Llaima volcano located at the western edge of the Andes in Araucania Region, Chile. The signals were recorded from the LAV station between 2010 and 2016.

Quantifying the Role of 3D Fault Geometry Complexities on Slow and Fast Earthquakes

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Traditional models of slow slip events (SSEs) oversimplify fault geometry, although imaging shows subduction faults are segmented and complex. We examine how fault interactions control slip behavior using 3D quasi‐dynamic simulations of two parallel faults with uniform rate‐weakening friction accelerated by hierarchical matrices.
