Izalco (in Nawat: Itzalku) is a municipality in the Sonsonate department of El Salvador. Volcan Izalco is an icon of the country of El Salvador, a very young Volcano on the flank of Santa Ana volcano. From when it was born in 1770 until 1966, it was in almost continuous eruption and was known as the "lighthouse of the Pacific." Since then it has been nearly inactive.
Izalco is a stratovolcano on the side of the Santa Ana Volcano, which is located in western El Salvador. It is situated on the southern flank of the Santa Ana volcano. Izalco erupted almost continuously from 1770 (when it formed) to 1958 earning it the nickname of "Lighthouse of the Pacific", and experienced a flank eruption in 1966. During an eruption in 1926, the village of Matazano was buried and 56 people were killed. The formation of the volcano actually occupied highly arable land on the southern slope of the Santa Ana volcano which was used for the production of coffee, cacao and sugar cane
