Details for: San Martin
Volcán San Martín, part of the Tuxtla volcanic field, is a broad alkaline shield volcano on the coast of the Gulf of México. San Martín is elongated in a NW-SE direction. The summit and flanks of the 1650-m-high volcano are dotted with more than 250 pyroclastic cones and maars. The two largest historical eruptions took place in 1664 and 1793. The 1793 eruption occurred from two cinder cones in the 1-km-wide summit crater and produced widespread ashfall and lava flows that extended 3.5 km down the NE flank.
