Citizen Scientists Help Detect and Classify Dynamically Triggered Seismic Activity in Alaska

Frontiers in Earth Science, 2020
In this citizen science project, we ask citizens to listen to relevant sections of seismograms that are converted to audible frequencies. Citizen scientists helped identify local seismic events whose recorded signals are much smaller than those ...

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

Geomorphological insight into changing tectonic regime, Pasinler Basin, Turkey [PDF]

, 2008
The Pasinler Basin, in the East Anatolian Contractional Province, features a suite of geomorphological zones, visible in the field, air photographs and Landsat and SRTM DEM imagery. These zones reflect past and current tectonically influenced processes.

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.

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

Structural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...

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 ...

Cascadia Slow Earthquake Behaviors Modulated by Tectonic and Environmental Forcings

Geophysical Research Letters
Slow earthquakes, including episodic tremor and slip (ETS), are highly sensitive to small stress perturbations, yet their links to tectonic and non‐tectonic forcings remain unclear.

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.
