Sicilian site of some volcanic lightning sightings (4)

I believe the answer is:

etna

(Other definitions for etna that I've seen before include "Explosive type" , "Dangerous peak" , "Volcano; reverse of stake" , "Europe's highest active volcano" , "Sicilian landmark" .)

I've seen this clue in the USA Today.
