Abstract
The detection of volcanic plumes produced during explosive eruptions is important to improve our under-
standing on dispersal processes and reduce risks to aviation operations. The ability of Global Position-ing
System (GPS) to retrieve volcanic plumes is one of the new challenges of the last years in volcanic plume de -
tection. In this work, we analyze the Signal to Noise Ratio (SNR) data from 21 permanent stations of the GPS
network of the Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio Etneo, that are located on the Mt.
Etna (Italy) flanks. Being one of the most explosive events since 2011, the eruption of November 23, 2013 was
chosen as a test-case. Results show some variations in the SNR data that can be correlated with the presence of
an ash-laden plume in the atmosphere. Benefits and limitations of the method are highlighted.
