Volcanic and Tectonic Sources of Seismicity Near the Tanaga Volcanic Cluster, Alaska

Geochemistry, Geophysics, Geosystems, 2023
Tanaga Island in the Central Aleutian Islands includes four stratovolcanoes: Sajaka, Tanaga, and East Tanaga in the northwest, and Takawangha in the central part of the island. Of these volcanoes, only Tanaga has a confirmed record of historical eruptive

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.

Automated hypocenter determination of tectonic tremors in the Nankai subduction zone using convolutional neural networks combined with semblance analysis

Earth, Planets and Space
Recent advances in deep learning have enhanced our ability to analyze seismic waveforms. Here, we developed and evaluated a convolutional neural network (CNN) model to classify tectonic tremors, earthquakes, and noise in seismic waveform data recorded by

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

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

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.

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

Geophysical 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 ...

Possible Shallow Tectonic Tremor Signals Near the Deformation Front in Central Cascadia

Seismica
To better constrain the locking state of the shallow Cascadia megathrust, we investigate whether shallow tectonic tremor occurs near the deformation front at ~44.5°N during 2015-2024. We focus on two cabled buried ocean bottom seismometers (OBSs) on the
