Cenozoic Plate Tectonic Reconstructions and Plate Boundary Processes in the Southwest Pacific [PDF]

, 2005
The Australia-Pacific-Antarctic plate circuit has long been a weak link in global plate reconstruction models for Cenozoic time. The time period spanning chron 20 to chron 7 (43-25 Ma) is particularly problematic for global plate models because seafloor

Numerical Modelling of Late Pleistocene to Holocene Earthquake‐Induced Progressive Rock Slope Damage in the Paraglacial Serpentine Valley, Prince William Sound, Alaska

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Numerical modelling of earthquake‐induced progressive rock slope damage in the paraglacial Serpentine valley, Prince William Sound, Alaska. Repeated seismicity generates rock mass damage that may have conditioned areas of the slope for failure during present‐day ice retreat.

Detection of Interannual and Fine‐Scale Plate Coupling Variations Using Intraplate Earthquakes and Geodetic Data: Application to the Tohoku‐Oki Plate Boundary

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We propose a method to infer detailed spatiotemporal variations in interplate coupling by integrating geodetic and seismic data. It examines whether focal mechanisms of intraplate earthquakes occurring near the plate interface align with the stressing rates caused by a geodetically derived slip‐deficit rate model, evaluating deviations from a ...

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.

Source Effects in Higher‐Order Ambient Seismic Field Correlations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Ambient seismic noise interferometry is widely used for surface wave imaging. It typically requires synchronous station recordings and assumes uniform noise source distributions. Higher‐order correlations, such as the re‐correlation of the reconstructed direct waves C2 $\left({C}_{2}\right)$, enable imaging with asynchronous data and can ...

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

Earth, 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 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.

Bilateral Hypertrophic Olivary Degeneration and Holmes Tremor without Palatal Tremor: An Unusual Association [PDF]

, 2016
Background: Lesions in the Guillain–Mollaret triangle or dentate-rubro-olivary pathway may lead to hypertrophic olivary degeneration (HOD), a secondary trans-synaptic degeneration of the inferior olivary nucleus.

Characterizing Incoming Cocos Plate Structure Outboard of the Guerrero Gap and Adjacent Segments Offshore Mexico: Implications for Along‐Strike Variations in Megathrust Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Megathrust slip behavior in subduction zones can vary along‐strike, yet the mechanisms driving this variability remain uncertain. The Middle America trench offshore Mexico provides an ideal setting to investigate the structural controls on megathrust slip behavior.
