CATANIA, Italy, Oct. 5 (UPI) -- A slight increase in shaking was reported at Etna volcano on the island of Sicily but it does not appear in danger of eruption, volcano experts said Friday.
Activity on a recently opened crater has been registered since Wednesday, Italian news agency ANSA reported.
The activity has been accompanied by "a slight increase in volcanic shaking," volcano experts said.
Etna has experienced nine "eruptive events" this year. The volcano belched a plume of smoke in a full-blown explosion in January that led to the temporary closure of Catania airport.
