伊萨克火山是萨尔瓦多西部的火山，位于圣安娜火山的南麓，是圣安娜火山的寄生复式火山，自1770年形成至1958年几乎持续爆发，1966年发生火山爆发。1926年的爆发把附近的一个村落淹埋，造成56人死亡。

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
