Impact assessment of earthquake early warning systems in Central America

Earthquake Spectra, Volume 41, Issue 4, Page 3094-3122, November 2025.
Earthquake Early Warning (EEW) systems aim to alert users in advance of imminent shaking, enabling them to take action. In collaboration with local seismic agencies, the Swiss Seismological Service (SED), has developed national EEW systems across Central America.

Refining the Eruption Chronology of Atitlán Caldera Through Zircon Double‐Dating

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 3, March 2025.
Abstract Precise dating of Quaternary volcanism is vital for risk mitigation, understanding volcano‐climate interactions, and deciphering the evolution of large silicic magmatic systems. The Atitlán caldera in Guatemala has experienced major eruptions that challenge radiometric dating techniques and complicate eruption chronology in this densely ...

Widespread D″ ${\mathbf{D}}^{\mathbf{{\prime\prime}}}$ Anisotropy Beneath North America and the Northeastern Pacific and Implications for Upper Mantle Anisotropy Measurements

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 10, October 2024.
Abstract Observations of seismic waves that have passed through the Earth's lowermost mantle provide insight into deep mantle structure and dynamics, often on relatively small spatial scales. Here we use SKS, S2KS, S3KS, and PKS signals recorded across a large region including the United States, Mexico, and Central America to study the deepest mantle ...

Investigating the Last Millennium Coulomb Stress Transfer in the Central Apennine Fault System (CAFS)

Tectonics, Volume 43, Issue 10, October 2024.
Abstract The Central Apennine Fault System (CAFS) characterizes an active tectonic region of significant importance, witnessing numerous destructive seismic events over the last millennia. Although numerous studies have underscored the role of Coulomb stress transfer (CST) in initiating some of the most catastrophic earthquakes, investigations focusing

Mechanical Energy Dissipation During Seismic Dynamic Weakening in Calcite‐Bearing Faults

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.
Abstract Earthquakes are frictional instabilities caused by the shear stress decrease, that is, dynamic weakening, of faults with slip and slip rate. During dynamic weakening, shear stress depends on slip, slip rate, and temperature, according to constitutive laws governing the earthquake rupture process.

The 3D Crustal Structure in the Epicentral Region of the 1980, Mw 6.9, Southern Apennines Earthquake (Southern Italy): New Constraints From the Integration of Seismic Exploration Data, Deep Wells, and Local Earthquake Tomography

Tectonics, Volume 43, Issue 5, May 2024.
Abstract We present the first 3D crustal model of the epicentral region of the 1980, Mw 6.9, normal‐faulting Irpinia earthquake (southern Italy) determined by jointly interpreting the CROP‐04 deep seismic profile, a grid of commercial seismic lines, deep exploration wells, and a high‐resolution Local Earthquake Tomography.

Precipitation homogenization and trends in the Usumacinta River Basin (Mexico‐Guatemala) over the period 1959–2018

International Journal of Climatology, Volume 44, Issue 1, Page 108-125, January 2024.
The homogenization and imputation of instrumental data records (1959–2018) from 60 meteorological stations within the Usumacinta River Basin (Mexico and Guatemala) significantly improved temporal and spatial coherence of the original dataset. Spatiotemporal precipitation variability was influenced by local topography and El Niño–Southern Oscillation ...
