地質学的概要
Volcán Sangangüey, the highest volcano of the NW-SE-trending Tepic-Zacoalco graben, is an eroded andesitic and dacitic stratovolcano that contains a prominent lava spine at its summit. The NW and SE flanks of the Pleistocene edifice have 45 cinder cones that erupted during the past 300,000 years along five parallel lines. Some of the cinder cones appear morphologically similar to cones on nearby Ceboruco volcano that are known to be less than 1,000 years old. There are no confirmed historical eruptions from Sangangüey. An incorrect report of an eruption in 1859 from San Juan (a synonym of Sangangüey) refers to the nearby Pleistocene San Juan volcano. An native tradition records an eruption in 1742 (Sapper, 1917), which may refer to activity from one of the flank cinder cones.
