The Oaxaca Mexico, earthquake of 29 november 1978: a preliminary report on aftershocks
Geofísica Internacional, 1978 El área de réplicas del período del 1 o. al 12 de diciembre de 1978 para el temblor de Oaxaca (29 de noviembre, 1978; Ms= 7.8) se estima en 6000 km2. El temblor· parece llenar el tramo de quietud sísmico entre los temblores de 196.5 (Ms =7.6) y .1968 ...

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 ...

The 29 november, 1978, Oaxaca earthquake: foreshock activity
Geofísica Internacional, 1978 El análisis de la .actividad sísmica (m≥2.8) registrada por medio de una red local de 6 sismográfos durante 3 semanas previas a la ocurrencia de un fuerte temblor (29 de. Noviembre de 1978, Ms=7.8) en Oaxaca-, revela los siguientes aspectos (Ponce et al.,

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 ...

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

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.
