There are no Holocene eruptions known for Los Humeros. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title. Additional discussion of data sources can be found under Volcano Data Criteria.

Los Humeros is the easternmost of a series of silicic volcanic centers with active geothermal systems located north of the axis of the Mexican Volcanic Belt. The first major silicic eruption produced the 230 cu km Xáltipan Ignimbrite about 460,000 years before present (BP), which covered about 3500 sq km and resulted in formation of the 15 x 21 km Los Humeros caldera. The emplacement of post-caldera lava domes and eruption of the 40 cu km Faby Tuff about 240,000 years BP was followed by eruption of the Zaragoza Tuff about 100,000 years BP and formation of the nested 10-km-wide Los Potreros caldera. A third and much smaller caldera (El Xalapazco) was formed about 40,000-20,000 years BP. The most recent eruptions at Los Humeros produced extensive morphologically youthful basaltic lava flows that are undated, but are younger than a 20,000 years BP rhyolitic lava flow and could be in part of early Holocene age (Negendank et al., 1985). Hot springs and fumarolic activity continues at Los Humeros, which is a producing geothermal field, the second developed in the Mexican Volcanic Belt.
