Hydrochemical dynamics of the “lake–spring” system in the crater of El Chichón volcano (Chiapas, Mexico)

open access: yes, 2008
El Chichón volcano (Chiapas, Mexico) erupted violently in March–April 1982, breaching through the former volcano–hydrothermal system. Since then, the 1982 crater has hosted a shallow (1–3.3 m, acidic (pH ∼ 2.2) and warm (∼ 30 °C) crater lake with a ...

Petrologic characteristics of the 1982 and pre-1982 eruptive products of el Chichon Volcano, Chiapas, México

open access: yesGeofísica Internacional, 1987
Los estudios petrográficos, macroquímicos y por microsonda de una secuencia de rocas del Volcán El Chichón, Chiapas, México, indican que los materiales “juveniles” de las erupciones de 1982 y las anteriores presentan esencialmente la misma química y la ...

Attributing the Stratospheric Impacts From the Water‐Rich Explosive Hunga Volcanic Eruption of 2022

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The January 2022 Hunga volcanic eruption injected an unprecedented ∼150 Tg of water vapor (H2 ${\mathrm{H}}_{2}$O) and ∼0.4 Tg of sulfur dioxide (SO2 ${\text{SO}}_{2}$) into the stratosphere. Observational studies confirm that this perturbation triggered significant changes in stratospheric composition and dynamics.

Los dioses contra el azar versus el azar de los dioses: las catástrofes "naturales" y los pueblos indígenas

open access: yesAmérica Latina Hoy, 2009
RESUMEN: ?Las catástrofes de la naturaleza y las de contenido político son similares en la medida en que pueden ser pre- visibles, también es el hecho de que las consecuencias de las primeras son directamente proporcionales a la mise- ria de la zona en ...

Uneven Responses of Regional Terrestrial Ecosystem Carbon Turnover Time to Stratospheric Aerosol Injection

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Stratospheric Aerosol Injection (SAI) is one of the alternative approaches to counteract anthropogenic warming by introducing reflective aerosols into the stratosphere. SAI‐induced surface cooling and altered hydrological cycle have been widely investigated.

Volcanic Eruptions Reorganize Climate Teleconnections: Detection via Riemannian Covariance Fingerprinting

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Standard detection and attribution of volcanic forcing targets spatial temperature anomalies. We show that the covariance structure of climate variability carries an independent volcanic fingerprint. Applying tangent‐space regression on the symmetric positive definite manifold SPD(8) to 40 years of eight teleconnection indices, we detect ...

Stratospheric impact of El Chichón [PDF]

open access: yes, 1984
Se colectaron aerosoles y gases estratosféricos mediante aviones de elevada altitud y balones para determinar el efecto de El Chichón sobre la estraiosfera. El Chichón inyectó compuestos sulfurosos que resultaron en la producción de alrededor de 7 .6 ± 2.
