San Miguel volcano rises from an elevation of approximately 100 m on the eastern coastal plain of El Salvador. With respect to its relief and general symmetry it is the most impressive volcano of El Salvador. Northeast of the volcano (approximately 15 km) lies the city of San Miguel (population ~300,000), which is the center of commercial activity of the eastern half of El Salvador.

Structurally, San Miguel volcano lies on the southern fault of the Central American graben at an intersection with NW-SE faults, which are evident by the alignment of radial fissures that erupted lava flows in 1844 and 1855.
