From Wikipedia
Niuatahi or Volcano O is a submarine volcano located in the far northern territory of Tonga. Since the cone in the middle is named Motutahi, the volcano is sometimes referred to as Niuatahi-Motutahi. Despite not having any record of any eruption, Niuatahi does have a record of recent hydrothermal activity.
