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

open access: yesTectonics, 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

Focal mechanism of six large earthquakes in northern Oaxaca, Mexico, for the period 1928-1973

open access: yesGeofísica Internacional, 1978
Con el fin de ayudar a comprender el neotectonismo en la región norte de Oaxaca, se estudiaron 6 temblores fuertes (mb≥6.5) de profundidad intermedia que ocurrieron durante los últimos 50 años (1928-1973) en dicha región.

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

open access: yesJournal 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.

Source mechanism of the november 29, 1978, Oaxaca, Mexico earthquake - a large simple event

open access: yesGeofísica Internacional, 1978
El reciente temblor de Oaxaca, México (Ms = 7.8) es de especial interés pues se localiza dentro de un tramo de quietud (“gap”) sísmica determinado previamente.

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

open access: yesTectonics, 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

open access: yesInternational 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 ...

Possible lateral stress interactions in a sequence of large interplate thrust earthquakes on the subducting Cocos and Rivera plates

open access: yesGeofísica Internacional, 2007
Los grandes sismos en la zona de subducción de México presentan, en ocasiones, agrupamientos espacio–temporales. Ha sido sugerido que dichos agrupamientos pueden ser debidos a la interacción de esfuerzos entre estos eventos.
