Volcano San Martin Tuxtla dominates the San Andrés Tuxtla
skyline. The central cone towers to 5700 feet topped with a
3/4 mile wide crater. There are dozens of other named
volcanic cones in the area, and many host the remnants of
the previously extensive rain forests.
Access to the higher reaches of the volcano is severely limited, although
guide service is offered in Ruiz Cortines. The village of Nacimiento de
Xogapan is actually the closest access, and is the startup for annual
pilgrimages to the top of the volcano to pick flowers alleged to bring luck and
happiness.
Volcán San Martín Tuxtla is also known as Titépetl (Nahuatl language for
Cerro de la Lumbre o del Fuego, Fire mountain), and actually showed a little
bit of a snowy top in 1997.
The two largest historical eruptions took place in the early 1500's, 1664 and
1793. The 1793 eruption occurred from two cinder cones in the summit
crater and produced widespread ash fall and lava flows that extended 2
miles down the NE flank. 2 other disputable minor seismic events may have
occured in 1838 and 1932. Fumaroles have been reported as late as the mid
20th century.
