Nea Kameni and the neighbouring small island Palea Kameni (the new and old burnt islands) have formed over the past two millennia by repeated eruptions of dacite lava and ash.
Nea Kameni e o veciño illote de Palea (ou Palia) Kameni (a nova e vella illas queimadas) formáronse nos últimos dous milenios polas repetidas erupcións de lava dacita e cinzas.
