One of the major traditions of Nejapa is Las Bolas De Fuego ("Balls of Fire"), celebrated August 31st.

The historical version explains that the local volcano El Playon erupted in November 1658 and forced the villagers of the old Nejapa village (known as Nixapa) to flee and settle at its current location.

The religious version explains how Saint Jerome fought the Devil with Fire Balls.

Participants engage in a planned fire-fight to commemorate the volcanic eruption in 1922.
