The Izalco volcano ( Spanish: Volcán de Izalco ) is a volcano in the Santa Ana department in El Salvador .
Emergence
The Izalco volcano is the youngest volcano in El Salvador and one of the youngest on the American continent. It was created in 1770 when smoke and ash poured from a stroma on the southern flank of the Volcán Santa Ana . 196 years to 1958 the new volcano had almost uninterrupted eruptions. The eruptions were so regular that it was used as a Faro del Pacífico (Lighthouse of the Pacific) for orientation for shipping on the Pacific . The eruptions formed a cone 650 m high above the plain, which corresponds to 1,952 m above sea level. In a volcanic eruption in 1926, the village of Matazano was buried and 56 people were killed.
The crater has a diameter of 250 meters. The last eruption was in 1966. A hotel had been built on nearby Cerro Verde , overlooking the erupting volcano, but the volcano stopped erupting shortly before the hotel was completed.
Since then, a reduction in the activity and temperature of its smoke gases has been noted. The Izalco is a stratovolcano with strombolian activity . The last eruption was massive and destroyed the top of the volcano, causing the height of the volcano to decrease by 200 meters. The volcano is located in a productive area of coffee fincas, cocoa trees and sugar cane fields.
