Sanganguey

Stratovulcano · Mexico · 2340 m

Sangangüey is an eroded stratovolcano that is seen here from the SW across farmlands of the Tepic basin, with a spine visible in the summit crater. The NW and SE flanks contain 45 scoria cones that erupted during the past 300,000 years; some of these NW-flank cones are visible below the left horizon.

Sintesi geologica

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.

There has been no confirmed historical eruptions, and the volcano is believed to be dormant; although an indigenous legend recorded the volcano erupting in 1742. The eruption is believed to be one occurring on a flank cinder cone on the volcano. Within the last 300,000 years however, the volcano has produced 45 cinder cones and lava flows.
