Yasur volcano (Tanna Island, Vanuatu): Nov 2017 activity

A group of VolcanoDiscovery visited Yasur volcano as part of their Round The World volcano tour and stayed at the volcano during 19-22 November. The activity was at normal levels with frequent small to moderately strong strombolian explosions from multiple vents at intervals of often less than one minute.
