1 2 The elevation varies with volcanic activity. The volcano last erupted on November 22, 2018. It is frequently given as 3,350 m (10,990 ft), but many sources that support this concede that this is approximate. The coordinates given, which are consistent with SRTM data, are from a 2005 GPS survey. The elevation data are based on a LIDAR (Light Detection and Ranging) survey carried out in June 2007, see Neri, M.; และคณะ (2008), "The changing face of Mount Etna's summit area documented with Lidar technology", Geophysical Research Letters, 35 (9): L09305, Bibcode:2008GeoRL..3509305N, doi:10.1029/2008GL033740
