Volcano Type: Stratovolcano
Volcano Status: Historical
Last Known Eruption: 2005
Summit Elevation: 2381 m 7,812 feet
Latitude: 13.853°N 13°51’12″N
Longitude: 89.630°W 89°37’48″W
Santa Ana, El Salvador’s highest volcano, is a massive, 2381-m-high, dominantly andesitic-to-trachyandesitic stratovolcano that rises immediately west of Coatepeque caldera. Collapse of Santa Ana (also known as Ilamatepec) during the late Pleistocene produced a voluminous debris avalanche that swept into the Pacific Ocean, forming the Acajutla Peninsula. Reconstruction of the volcano subsequently filled most of the collapse scarp. The broad summit of the volcano is cut by several crescentic craters, and a series of parasitic vents and cones have formed along a 20-km-long fissure system that extends from near the town of Chalchuapa NNW of the volcano to the San Marcelino and Cerro la Olla cinder cones on the SE flank. Historical activity, largely consisting of small-to-moderate explosive eruptions from both summit and flank vents, has been documented since the 16th century. The San Marcelino cinder cone on the SE flank produced a lava flow in 1722 that traveled 13 km to the east.
Santa Ana Crater
Santa Ana volcano is located 30 miles west of San Salvador.The summit contains several crescentic craters, and a series of parasitic vents and cones have formed along a 20-km-long fissure system. San Marcelino cinder cone on the SE flank produced a lava flow in 1722 that traveled 13 km to the east. A sudden eruption occurred at Santa Ana volcano at 0820 hr on 1st October 2005. Ash was emitted to a height of 14 km and fell in towns west of the volcano, including in Naranjos, Nahuizalco, Juayúa, Ahuachapán, and La Hachadura. Two people were killed by landslides in the town of Palo Campana, and thousands of residents near the volcano were evacuated. Storms on 12th October produced lahars which traveled towards Coatepeque.
