According to a warning given by French and Italian researchers, Etna “is slowly transforming itself from an effusive volcano, which means one with a slow lava flow and low gas emission, into an explosive volcano. ”
Franču un itāļu speciālisti brīdina, ka Etna ” pamazām pārtop no tāda vulkāna, kam raksturīga lēna lavas plūsma un nelieli gāzu izmeši, vulkānā, kura izvirdumus pavada sprādzieni ”.
