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)

San Salvador edifice

The San Salvador edifice formed more than 70,000 years ago, creating an edifice about 10 to 14 km in diameter and 3000m above sea level. Later, an explosive eruptive episode called 'G-1' (about 40,000 to 50,000 years ago) formed a crater that was 4.5 km by 6 km in size. The Picacho and Jabali peaks are the remnants of this crater. The G-1 episode erupted a dacitic pumice effusion, likely in a plinian style eruption.

Boquerón edifice

The Boquerón edifice formed between 40,000 and 1580 years ago, filling up the G-1 eruption crater. the lavas of the Boquerón edifice contain more alkali element and iron oxide than the lavas of the san salvador edifice, allowing for a clear...
