Los Humeros is the largest caldera volcano in the Mexican volcanic belt. Its second largest caldera-forming eruption, the ca. 0.1 Ma Zaragoza eruption, is recorded by two Plinian pumice-fall layers and a zoned intra-Plinian ignimbrite. Diverse pumice types within the ignimbrite provide insights about the way that different magmas within a single ...

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.

Seismic models of the Los Humeros caldera (Mexico) using the GEMEX project data
2020<p>In the framework of the GEMEX project (cooperation between Europe and Mexico for geothermal development), a dense network of 45 stations was deployed in 2017-2018 in the Los Humeros caldera, Mexico.</p><p>Thanks to this network an intense local seismic activity has been recorded in the geothermal ...

Abstract We explored applications (including limitations) of Gauss's theorem to the study of silicic calderas. First it enables us to determine the mass deficiency from calderas. Mass deficiency itself has also other potential applications. It enables to make qualitative comparisons between calderas. We can use the mass deficiency to test, in a quick

We present results of our simulation study of the effects of the depth (top of the magma chamber at 5–10 km) and volume (1000–1400 km3) of the primary heat source beneath the Los Humeros caldera. The thermal gradient in the vicinity of the magma chamber calculated from the temperature excess (difference between the simulated and the initial ...

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).
