Abstract

AsubmarinegaseruptionstartedinNovember2002offshoreofPanareavolcano(AeolianIslands, Italy). Theintensityofthe gas emissionandtheconsiderableanomalies of thegeochemical andgeophysical parameters havealarmedthevolcanological communityandtheItalianCivil ProtectionAgencyonthepossibilitythat thisactivitymayrepresent avolcanicunrest at Panarea volcano. WeusedahighresolutionMarineDigital TerrainModel(MDTM), with0.5maccuracy, anddetailedunderwatersurveys byscubadivingtostudytheexhalationcentresandthegeological, morphological andstructural featuresof theseafloor andto clarifytherelationshipsbetweengasventsdistribution,submarinevolcanologicalstructuresandtherecentdeformationofthisarea. Theunderwatersurveysrevealedanexhalativefieldcharacterisedby21mainactivegasventsandcratersfrommetrestotensof metres indiameter, anda pervasive exhalationfromthe seafloor; hundreds of fossil craters associatedwithgas pipes and hydrothermal alterationarealsopresent ontheseafoor: craters, pipesandconduitsarenot associatedwithjuveniledepositsand relatetoalongstandinghistoryof gasexhalationanderuptions.
