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.

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 ...

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 ...

Regional gravity of los humeros volcanic area

Geofísica Internacional, 1978
En el extremo este del Eje Volcánico Transmexicano se encontró una anomalía gravimétrica negativa. Tectónicamente, dicha anomalía parece corresponder a un hundimiento en el que han tenido lugar varias.
