Fireballs Festival evokes Salvadoran volcano eruption Dozens of young people, separated into two camps, participate at the Fireballs Festival of Nejapa, some 20 km north of San Salvador. The tradition, more than 100 years old, began after the November 1658 eruption of the El Playon volcano, which forced the town to move to its current location. Authorities warn the festival can become dangerous as there are no rules. IMAGES
