圣萨尔瓦多火山距圣萨尔瓦市中心18公里。

火山直径1600米，深800米。古代火山喷发后这里形成了湖泊。

1917年6月17日火山再次喷发，湖水被蒸发，湖底留下一个坚固的圆锥形小熔岩，是圣萨尔瓦多火山口的奇特之处。火山北麓是一片宽阔的火山熔岩地带。

The San Salvador Volcano (also known as Quetzaltepec) is a stratovolcano situated northwest to the city of San Salvador.

The crater has been nearly filled with a relatively newer edifice, the Boquerón volcano.

The city of San Salvador is adjacent to the volcano and the western section of the city actually lies among its slopes.

Because of this close proximity, any geological activity of the volcano, whether eruptive or not, has the potential to result in catastrophic destruction and death to the city.

Despite this, the volcano is iconic of the city, and several TV and radio antennas are situated on the El Picacho peaks and the crater of Boqueron. El Picacho, the prominent peak is the highest elevation (1,960 meters altitude).
