Description:
The TOMO-ETNA experiment was devised to image of the crust underlying
the volcanic edifice and, possibly, its plumbing system by using passive
and active refraction/reflection seismic methods. This experiment
included activities both on-land and offshore with the main objective of
obtaining a new high-resolution seismic tomography to improve the
knowledge of the crustal structures existing beneath the Etna volcano and
northeast Sicily up to Aeolian Islands. The TOMO-ETNA experiment
was divided in two phases. The first phase started on June 15, 2014 and
finalized on July 24, 2014, with the withdrawal of two removable seismic
networks (a short period network and a broadband network composed
by 80 and 20 stations respectively) deployed at Etna volcano and
surrounding areas. During this first phase the oceanographic research
vessel (R/V) “Sarmiento de Gamboa” and the hydro-oceanographic vessel
(H/V) “Galatea” performed the offshore activities, which includes the
deployment of ocean bottom seismometers (OBS), air-gun shooting for
wide angle seismic refraction (WAS), multi-channel seismic (MCS) reflection
surveys, magnetic surveys and ROV (remotely operated vehicle)
dives. This phase finished with the recovery of the short period seismic
network. In the second phase the broadband seismic network remained
operative until October 28, 2014, and the R/V “Aegaeo” performed additional
MCS surveys during November 19-27, 2014. Overall, the information
deriving from TOMO-ETNA experiment could provide the answer
to many uncertainties that have arisen while exploiting the large amount
of data provided by the cutting-edge monitoring systems of Etna volcano
and seismogenic area of eastern Sicily.
