A new eruption, likely submarine, has occurred (or is still in progress) during the past days west of Vava'u Island in the Tonga archipelago. Its origin volcano is still a bit unclear, but the eruption, evidenced by fresh pumice rafts and steam plumes is most likely from a submarine volcano near or a vent of the small Fonualei volcano. On 7 Aug, an observer sent us the following report: "At around 10:40am on Wednesday 7 August, we noticed large clouds of smoke on the horizon at the location of Fonualei volcano. The plume continued to get larger over the next few hours. It seemed to pause and then erupt again."
