Data from the Global Volcanism Program of the Smithsonian Institution
Details for: San Miguel
Symmetrical San Miguel volcano towers 2000 m above a barren basaltic lava flow erupted from a SE-flank vent in 1819. The conical volcano is not the highest volcano in El Salvador, but is one of the most prominent, since it rises from near sea level on the Pacific coastal plain. San Miguel (also known as Chaparrastique) is one of the most active volcanoes of El Salvador, with more than two dozen eruptions recorded since the beginning of the Spanish era.

The symmetrical cone of San Miguel, one of the most active volcanoes in El Salvador, rises from near sea level to form one of the country's most prominent landmarks. A broad, deep, crater complex that has been frequently modified by eruptions recorded since the early 16th century caps the truncated unvegetated summit, also known locally as Chaparrastique. Flanks eruptions of the basaltic-andesitic volcano have produced many lava flows, including several during the 17th-19th centuries that extended to the N, NE, and SE. The SE-flank flows are the largest and form broad, sparsely vegetated lava fields crossed by highways and a railroad skirting the base of the volcano. Flank vent locations have migrated higher on the edifice during historical time, and the most recent activity has consisted of minor ash eruptions from the summit crater.
