Explosive Behavior of Intermediate Magmas: The Example of Cotopaxi Volcano (Ecuador)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 22, Issue 11, November 2021., 2021
Abstract The variability in intensity and style shown by explosive volcanism has been traditionally explained by a complex interplay among melt composition and pre‐eruptive volatile content, which modulate magma ascent and conduit dynamics. However, magmas having similar compositions may be characterized by subtle textural changes affecting magma ...

Escenarios de cambio climático (CMIP-5) para tres áreas naturales protegidas en el Eje Neovolcánico Transversal

open access: yesRevista Mexicana de Ciencias Forestales, 2018
Debido al cambio climático, los patrones de precipitación y temperatura ocasionarían cambios importantes en los ecosistemas del mundo. Los Modelos de Circulación Global (MCG) se utilizan para simular el clima a futuro y con ello se generan escenarios ...

Formation, production and viability of oospores of Phytophthora infestans from potato and Solanum demissum in the Toluca Valley, central Mexico [PDF]

open access: yes, 2001
Aspects of the ecology of oospores of Phytophthora infestans were studied in the highlands of central Mexico. From an investigation of a random sample of strains, it was found that isolates differed in their average capability to form oospores when ...

EXTRACCIÓN DE MADERA EN EL PARQUE NACIONAL NEVADO DE TOLUCA

open access: yesRevista Mexicana de Ciencias Forestales, 2019
La extracción de leña y madera en las localidades rurales dentro del área de influencia del Parque Natural Nevado de Toluca muestra un notable incremento; sin embargo, al desconocerse sus cantidades reales se plantea la necesidad de conocer las especies forestales que tienen un mayor grado de aprovechamiento, identificar sus ...

First record of the Pseudodiamesa branickii species group (Diptera: Chironomidae: Diamesinae) from central Mexico

open access: yesRevista Mexicana de Biodiversidad, 2020
Larvae and pupae of the Pseudodiamesa branickii species group (Makarchenko and Makarchenko, 1999) (Diptera: Chironomidae) were found in 2 high-altitude lakes (El Sol and La Luna, 4,200 m asl), in the crater of the Nevado de Toluca volcano, in central ...

Estudio de la distribución espacial del muérdago enano (Arceuthobium sp.) en el Nevado de Toluca, México utilizando el método del SADIE [PDF]

open access: yes, 2009
El Nevado de Toluca fue decretado como Parque Nacional, reconociendo su importancia como sitio de recarga de los acuíferos, así como el valor de sus recursos naturales. Hoy es, sin embargo, escenario de una acelerada depredación tanto humana como natural.

A Recurrent Magmatic Pattern on Observable Timescales Prior to Plinian Eruptions From Nevado de Toluca (Mexico)

open access: yesJournal of Geophysical Research: Solid Earth, Volume 124, Issue 11, Page 10999-11021, November 2019., 2019
Abstract Nevado de Toluca is a stratovolcano in the densely populated Mexican Highland and the source of three late Pleistocene Plinian eruptions. While the characterization of the magmatic processes and timescales, leading to these events, is crucial to evaluate potential signals of the reawakening of this volcano, they are not well constrained.

Explosive Eruptions With Little Warning: Experimental Petrology and Volcano Monitoring Observations From the 2014 Eruption of Kelud, Indonesia

open access: yesGeochemistry, Geophysics, Geosystems, Volume 20, Issue 8, Page 4218-4247, August 2019., 2019
Abstract Explosive eruptions that occur with little or no precursory unrest (less than a month) pose the greatest hazards from volcanoes to nearby populations. Here we focus on the preeruptive conditions for these explosive events, their triggers and how these eruptions evolve.
