Izalco is an icon of the country of El Salvador, a very young parasitic cone on the flank of Santa Ana volcano. From its first activity in 1770 until 1958, it was in almost continuous eruption and was known as the "lighthouse of the Pacific." Since then it has been nearly inactive.
Izalco was known for strombolian activity, the kind of lava fountaining that Stromboli, in Italy, is famous for. That eruption style may well have been the inspiration for "roman candle" fireworks.
