Sanganguey volcanSangangüey volcano is an eroded andesitic and dacitic stratovolcano stratovolcano 50 km from the west coast of Mexico. It is the highest volcano in the NW-SE-trending Tepic-Zacoalco graben.
Sangangüey contains a prominent lava spine at the summit and has 45 cinder cones on its NW and SE flanks, which are the youngest features of the volcano. They erupted during the past 300,000 years along 5 parallel NW-trending fissures.
There are no confirmed historic eruptions, but an Indian legend has recorded the memory of an eruption in 1742, which could have been from one of the flank cones that are similar to those of nearby Ceboruco volcano.
