The eastern Trans-Mexican Volcanic Belt is characterized by a diversity of volcanoes that are related to different processes and eruptive styles. The spectacular exposures of late Pleistocene and Holocene volcanism provide a unique opportunity to explore a variety of volcanic features and deposits that may be relevant for volcanic hazard assessments within the area. This three-day field guide describes selected representative examples of the regional volcanism showing volcanic features including thick pyroclastic successions derived from the explosive activity of Los Humeros caldera volcano, caldera-rim effusions, alternating explosive and effusive activity of a vitrophyric rhyolite dome (Cerro Pizarro), and the eruptive activity of two composi-tionally contrasting maar volcanoes: Atexcac, a classic basaltic maar and Cerro Pinto, a rhyolitic tuff ring—dome complex.
