Modeling Intra‐Caldera Resurgence Settings: Laboratory Experiments With Application to the Los Humeros Volcanic Complex (Mexico) [PDF]

Journal of Geophysical Research: Solid Earth, 2021
AbstractScaled analogue models explored the role of different boundary conditions in intra‐caldera resurgence processes. Models investigated the role of magma intrusion depth (ID) (Series 1), asymmetric and symmetric caldera collapse (Series 2), as well as the presence of existing discontinuities in the pre‐volcanic substratum (Series 3) on the style ...

Seismic imaging of the magmatic plumbing system and geothermal reservoir of the Los Humeros caldera (Mexico) using anisotropic shear wave models

Journal of Volcanology and Geothermal Research, 2022
Abstract Since the nineteen-eighties, the depth, number, position and shape of the heat sources feeding the super-hot geothermal system of the Los Humeros caldera (Mexico) is under debate. With the aim of providing a seismic constraint of this region, we present a high resolution three-dimensional anisotropic shear wave velocity model.

Geochemistry of Los Humeros Caldera, Puebla, Mexico

Bulletin of Volcanology, 1982
Geochemistry of Pliocene to recent volcanic rocks from Los Humeros caldera (19°30′ N – 19°50′ N and 97°15° W – 97°35′ W) in East-Central mexico is described. The volcanic rocks from this area seem to represent both alkali and high-alumina basalt series, or both calcalkaline and high-K calc-alkaline sequences.

Shallow structure of Los Humeros (LH) caldera and geothermal reservoir from magnetotellurics and potential field data

Geophysical Journal International, 2020
SUMMARYThis study focuses in the analysis of the internal structure of the upper 3 km of Los Humeros (LH) caldera and the relation of electrical and hydrothermal anomalies. For this purpose, we measured, processed and interpreted 78 broad-band magnetotelluric (MT) soundings.

An unusual syn-eruptive bimodal eruption: The Holocene Cuicuiltic Member at Los Humeros caldera, Mexico

Journal of Volcanology and Geothermal Research, 2014
Abstract The Cuicuiltic Member (CM) at Los Humeros Caldera, eastern Mexican Volcanic Belt is a Holocene (6.4 ka B.P.) succession of alternated fallout deposits of contrasting composition (trachydacite pumice and basaltic andesite scoria). The CM covers approximately 250 km2 on its proximal facies and its thickness ranges from 1.5 m to 8.0 m.

Magma genesis and chamber processes at Los Humeros caldera, Mexico—Nd and Sr isotope data

Nature, 1983
The Mexican volcanic belt (MVB), a roughly east–west structure, consists of many late Tertiary and Quaternary cindercones, domes, calderas and stratovolcanoes1,2. Los Humeros caldera (approximately 19°40′ N latitude, 97°25′ W longitude) lies on the northeastern part of the MVB where the belt overlaps with another major volcanic province, the Eastern ...
