Seismic models of the Los Humeros caldera (Mexico) using the GEMEX project data
, 2020Thanks to this network an intense local seismic activity has been recorded in the geothermal field and surroundings, from which it has been possible to identify high-frequency Volcano-Tectonic events (VT, >10 Hz) and Long-Period events (LP, 1-8 Hz).

Geophysical Journal International, 2020 This 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

Journal of Volcanology and Geothermal Research, 2021 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 Volcanologique, 1982Geochemistry 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.

Geochemical evidence for a lithospheric source for magmas from Los Humeros caldera, Puebla, Mexico
Chemical Geology, 2000Abstract This study reports new geochemical and Sr–Nd–Pb radiogenic isotope data on hy-normative Quaternary basaltic to rhyolitic volcanic rocks as well as two samples of Mesozoic to Palaeozoic intrusive igneous rocks from Los Humeros caldera (LHC), located in the eastern part of the Mexican Volcanic Belt (MVB).

Alkali and alkaline earth element geochemistry of Los Humeros Caldera, Puebla, Mexico
Journal of Volcanology and Geothermal Research, 1984Abstract Results of the measurements of alkali (K, Rb and Cs) and alkaline earth (Ba and Sr) elements on seven pre-caldera and twenty post-caldera samples of Los Humeros volcanics (Pliocene to Recent) are described. These data are interpreted in terms of the known solid-liquid partition coefficients.

Los Humeros caldera is a Quaternary volcanic structure located on the eastern portion of the Mexican volcanic belt. Geothermal exploration, including well drilling, is presently carried out; geophysical surveys over the 200 km’ structure include aeromagnetometry, gravimetry, tellurics, self-potential, resistivity soundings (Schlumberger).
