Enhanced deep learning approach for detecting and locating tectonic tremors in the Nankai subduction zone

open access: yesEarth, Planets and Space
Tectonic tremors are key indicators of slow-slip phenomena, and detecting them accurately is a challenging task. Conventional techniques often fail to detect tremors during periods of intense tremor activity.

Aeromagnetic mapping of fault architecture along Lagos–Ore axis, southwestern Nigeria

open access: yesOpen Geosciences, 2020
A seismic wave is released when there is sudden displacement on a fault plane. The passage of this wave along the fault plane or within the lithosphere could result in ground shaking or vibration at the surface of the Earth.

Along‐Strike Coupling Heterogeneity in Cascadia's Slow‐Slip Zone Constrained by GNSS and Reduced‐Order Rate‐And‐State Friction Modeling

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter‐SSE coupling inversion with Bayesian inference of a quasi‐dynamic rate‐and‐state friction SSE‐cycle ...

Detection of Shallow Tectonic Tremors in Hyuga‐nada, Nankai Trough, Using the Newly Established N‐Net OBS Network

open access: yesGeophysical Research Letters
Monitoring tectonic tremors is crucial for understanding stress release in subduction zones and assessing megathrust earthquake risk. The Hyuga‐nada region, at the western edge of the Nankai Trough, Japan, provides a natural laboratory for investigating ...

Numerical Simulations of 3D Scattering Structures Reveal Systematic Underestimation of Marsquake Magnitudes

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Determining marsquake magnitudes is essential for assessing seismic activity on Mars, yet previous estimates neglect three‐dimensional (3D) scattering effects. The exceptionally long‐lasting coda of the largest recorded marsquake, S1222a, provides a unique opportunity to quantify how crustal heterogeneities affect waveform propagation and ...

Dystonic Head Tremor and the Coexistence of Headache [PDF]

open access: yes, 2017
Background: Head tremor may be observed in the presence of cervical dystonia and sometimes coexists with headache. We wished to investigate the presence of headache in dystonic head tremor.Methods: We studied the files of 19 patients from our ...

An Integrated Geophysical Approach to Track Magma Intrusion: The 2018 Christmas Eve Eruption at Mount Etna

open access: yesGeophysical Research Letters, 2019
On 24 December 2018, a violent eruption started at Mount Etna from a fissure on the southeastern flank. The intrusive phenomenon, accompanied by intense Strombolian and lava fountain activity, an ash‐rich plume, and lava flows, was marked by significant ...

Statistical characteristics of non-volcanic tremor distributions along the Mexican Subduction Zone [PDF]

open access: yesSolid Earth
We analyze the statistical characteristics of non-volcanic tremor (NVT) sequences in the Mexican subduction zone. To this end, we employ various techniques, including the Gutenberg–Richter relationship, non-extensive statistics, and multifractal ...

A Rare Presentation of Orthostatic Tremor as Abdominal Tremor [PDF]

open access: yes, 2018
Background: Orthostatic tremor (OT) is a weight-bearing hyperkinetic disorder characterized by unsteadiness while standing that is relieved when sitting or walking. Case report: A 66-year-old male presented with a 5 year-history of tremor in his abdomen,
