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

Can tectonic events change volcanic tremor at Stromboli? [PDF]

Geophysical Research Letters, 2006
Besides the well known strombolian activity, Stromboli shows the presence of a continuous volcanic tremor. Tectonic events in the area are rare and no evidence of a local tectonic event changing the characteristics of the tremor was previously known.

Using Tectonic Tremor to Constrain Seismic Wave Attenuation in Cascadia [PDF]

Geophysical Research Letters, 2018
AbstractTectonic tremor can be used to constrain seismic wave attenuation for use in ground motion prediction equations in regions where moderately sized earthquakes occur infrequently. Here we quantify seismic wave attenuation by inverting tremor ground motion amplitudes in different frequency bands of interest, to determine frequency dependence of ...

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

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.

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 ...

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

Induced Seismic Events—Distribution of Ground Surface Displacements Based on InSAR Methods and Mogi and Yang Models

Remote Sensing, 2021
In this article, we present a possible approach to use satellite radar data for a complete description of the formation process of a subsidence trough resulting from an induced seismic event—a mining tremor.

Deep Seismic Tremors in the 2025 Santorini Seismo‐Volcanic Crisis Highlight Magmatic Feeding From a Mid‐Crustal Reservoir

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An intense seismic swarm started on 27 January 2025 in the Santorini‐Amorgos region and lasted for approximately 45 days. A widely observed seismic tremor on 14 February 2025 suggested a volcanic origin for the 2025 Santorini crisis. Here we present an in‐depth combined seismological analysis of the earthquakes and tremors that occurred during
