Izalco is an active stratovolcano[2] on the side of the Santa Ana Volcano, which is located in western El Salvador.

The volcano erupted on highly arable land which was used for the production of coffee, cacao, and sugar cane.

Today, Izalco experiences only fumarolic activity in the form of rainwater seeping into the volcano and contacting hot rocks, rather than steam emissions from underground gases.

It is the type locality for the copper vanadium minerals: bannermanite, blossite, fingerite, howardevansite, lyonsite, mcbirneyite, stoiberite and ziesite.

[6] The volcano is visited and climbed regularly by tourists to El Salvador via the Cerro Verde National Park and is a national icon of the country, even featured on the 10 colón bank note (US dollars replaced the colon in 2001, so the bank note is no longer in circulation).
