Yasur is a small stratovolcano located inside a large caldeira, in the south-eastern part of Tanna Island (South Vanuatu). The summit crater is occupied by three vents: the vents A and B in the southern subcrater and the vent C in the northern subcrater. Yasur's activity is characterized by explosions of gas bubbles and the emission of small ash plumes. In order to better understand the volcanic processes that occured inside the edifice, a large seismic network, consisting of 12 antennas and 10 broadband stations, was deployed around Yasur volcano in 2008, recording continuously the seismic signal. The superficial velocity structure of Yasur volcano and of the Siwi caldeira was estimated up to 200 meters using the Spatial Autocorrelation an...
