Near San Juan Opico, San Salvador, El Salvador — Central America (West Coast)
The San Salvador Volcano Complex
Centroamérica se halla en una zona de contacto entre dos placas tectónicas: la Placa de Cocos y la Placa del Caribe, que interactúan creando una cinta volcánica llamada Cinturón de Fuego del Pacífico. Así, podemos encontrar volcanes del oriente hasta el poniente del país.
El Volcán de San Salvador
El Volcán de San Salvador, con una altura de 1960 msnm. Se halla señoreando la capital San Salvador. Está conformado por los restos de erupciones múltiples: una silueta de elevada y aguda cumbre en su parte oriental (El Picacho, 1960 m.), una parte central más chata con un gran cráter (El Boquerón, 1893.39 m.) y una cima menos prominente al noroeste, llamada El Jabalí. Todo el complejo abarca una superficie de 110 km2.
El Volcán ha hecho erupción en varias ocasiones en los últimos 70.000 años, a través de su cráter central, así como por fisuras en sus flancos. En un radio de 10 kms. alrededor se encuentran diversos conos de escoria-cenizas y cráteres de explosión.
Sabría usted que: Prácticamente todo el subsuelo del país (más de un 90%) está formado por materiales volcánicos.

The Volcano of San Salvador
The Volcano of San Salvador has a height of 1960 masl (meters above mean sea level). It overlooks the capital of San Salvador. It is formed by the remains of multiple eruptions: a silhouette with a high and sharp summit on its eastern part (El Picacho, 1960 m.), a more flat central part with a large crater (El Boquerón, 1893.39 m.) And a prominent lower summit, called El Jabalí (The Wild Boar). The whole complex covers an area of 110 square kilometers.
The volcano has erupted several times in the last 70,000 years, through both its central crater as well as through fissures on its flanks. Within a radius of 10 kms. around it are various cones of slag-ash and explosive craters.
Did you know? Practically all the subsoil of the country (more than 90%) is formed by volcanic materials.
