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.

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.

Effective mapping of large ignimbrites by using a GIS-based methodology; case of the Xáltipan ignimbrite from Los Humeros caldera, Mexico

Terra Digitalis, 2019
The Xáltipan ignimbrite records the largest single-eruption of the Trans-Mexican Volcanic Belt up to date (≥344 km3 uncompacted volume). As most large ignimbrites, this ignimbrite presents common challenges when mapping.

Imaging the deep structures of Los Humeros geothermal field, Mexico, using three-component seismic noise beamform [PDF]

, 2020
We present a 1D shear‐velocity model for Los Humeros geothermal field (Mexico) obtained from three‐component beamforming of ambient seismic noise, imaging for the first time the bottom of the sedimentary basement ∼5  km below the volcanic caldera, as ...

Local Earthquake Tomography at Los Humeros Geothermal Field (Mexico)

Journal of Geophysical Research: Solid Earth, Volume 125, Issue 12, December 2020., 2020
Abstract A passive seismic experiment using 25 broadband and 20 short‐period stations was conducted between September 2017 and September 2018 at Los Humeros geothermal field, an important natural laboratory for superhot geothermal systems in Mexico. From the recorded local seismicity, we derive a minimum 1‐D velocity model and obtain 3‐D Vp and Vp/Vs ...

The impact of hydrothermal alteration on the physiochemical characteristics of reservoir rocks: the case of the Los Humeros geothermal field (Mexico) [PDF]

, 2022
Hydrothermal alteration is a common process in active geothermal systems and can significantly change the physiochemical properties of rocks. To improve reservoir assessment and modeling of high-temperature geothermal resources linked to active volcanic ...
