Estratigrafía e historia eruptiva de la erupción pliniana que originó la Pómez Xoxoctic, Caldera Los Humeros, México

Geofísica Internacional
La Pómez Xoxoctic (PX) representa uno de los eventos explosivos post-colapso más significativos del Complejo Volcánico de Los Humeros (Pleistoceno superior, entre 28 y 50 ka), clasificado como una erupción pliniana multifásica de Magnitud 5.3 y VEI 4. El

Regional gravity of los humeros volcanic area

Geofísica Internacional, 1978
En el extremo este del Eje Volcánico Transmexicano se encontró una anomalía gravimétrica negativa. Tectónicamente, dicha anomalía parece corresponder a un hundimiento en el que han tenido lugar varias.

Production‐Induced Subsidence at the Los Humeros Geothermal Field Inferred from PS‐InSAR

Geofluids, Volume 2019, Issue 1, 2019., 2019
Surface deformation due to fluid extraction can be detected by satellite‐based geodetic sensors, providing important insights on subsurface geomechanical properties. In this study, we use Differential Interferometric Synthetic Aperture Radar (DInSAR) observations to measure ground deformation due to fluid extraction at the Los Humeros Geothermal Field (

Sassolite Precipitation at the Restless Campi Flegrei Volcano in Italy Points to Hydrothermal Flashing by Deep Boron‐Rich Brines

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Studying the behavior of dormant volcanoes is a major challenge in volcanology. Here, we conducted a 10‐year survey of hydrothermal mineralization at Campi Flegrei, an active volcano near Naples in Italy, which last erupted in 1538. Our survey revealed a significant output of boric acid at the hydrothermal sulfate discharge area of Pisciarelli,

Interpreting compositional zonation of the Zaragoza ignimbrite from Los Humeros caldera, Central Mexico

IOP Conference Series: Earth and Environmental Science, 2008
Compositional zonation in ignimbrites is relatively common, and is often inferred to record gradual withdrawal by an eruption of a density-stratified magma chamber (with silicic magma towards the top and more dense, mafic magma at the bottom). We show that this model does not match observations at the ca.

Hydrothermal Signatures Discovered in Outcropping Rocks of the Los Humeros Geothermal Field (Mexico): A Geochemometric Exploration Case Study

Geofluids, Volume 2024, Issue 1, 2024.
Hydrothermal geochemical signatures in outcropping rock samples of the super‐hot Los Humeros geothermal field were discovered by using an integrated geochemometric study of the mobility of components (major oxides) and trace elements. Chemical component and element mobilities were determined by using the Gresens–Grant equation for mass balances.
