San Martín volcano

Shield volcano 1650 m / 5,413 ft
Mexico, 18.57°N / -95.17°W
Current status: normal or dormant (1 out of 5)

San Martín volcano (Volcan de San Martín Tuxtla) is a broad basaltic shield volcano that rises above the Gulf of Mexico, and is part of the Tuxtla volcanic field. It has a 1 km wide summit caldera containing 2 smaller scoria cones which formed during the violent 1793 summit eruption that produced wide-spread ash fall and lava flows traveling 3.5 km from the summit.
There are more than 250 flank cones dotted on the flanks of the volcano indicating frequent flank eruptions. The largest historic eruptions were in 1664 and 1793. At present, there is fumarolic activity in the summit caldera.

Background

The massive volcano, also known as , is elongated in a NW-SE direction and is capped by a 1-km-wide summit crater. The upper part of the 1650-m-high volcano is covered with dense tropical rain forests. The summit and flanks of San Martín are dotted with more than 250 pyroclastic cones and maars. Well-preserved cinder cones are abundant between the summit of the volcano and Laguna Catemaco on the SE flank. Holocene cones in this area produced ash deposits that buried recently discovered stone pyramids.
