San Martin Tuxtla
The isolated San Martin Tuxtla volcano is a shield volcano which rises above the Gulf of Mexico. It has had eruptions in historical times. It occurs in the Tuxtla volcanic field in Veracruz, Mexico. Lavas from San Martin vary between basanite and alkali basalt.〔(Nelson, Stephen A. and Gonzalez-Caver, Erika; ''Geology and K-Ar dating of the Tuxtla Volcanic Field, Veracruz, Mexico,'' Bulletin of Volcanology, Volume 55, Issue 1-2, pp. 85-96 )〕 Locally the volcano is also known as Tiltépetl (Black mountain in the Nahuatl language).
==Morphology==
San Martin forms a broad shield volcano, it rises to a height of 1680 m and is capped by a 1 km wide summit crater which is 150 m in depth. The crater contains two pyroclastic cones that were the source of the large 1793 eruption. The flanks of the volcano are dotted with 250 pyroclastic cones and maars, some of which have been active in historical times. The volcano is currently densely forested.〔(Global Volcanism Program )〕
