Tofua is a non-instrumented, remote, island volcano that is seldom the subject of reports; it continued to emit at least low-level eruptions well into 2011. This small volcanic island lies in southern Tonga (see map and other figures in BGVN 34:02), ~ 1,700 km NNE of New Zealand.

May 7, 2024 · The low, forested Tofua Island in the central part of the Tonga Islands group is the emergent summit of a large stratovolcano that was seen in eruption by Captain Cook in 1774. The summit contains a 5-km-wide caldera whose walls drop steeply about 500 m.

The symmetrical Kao rises steeply from the ocean about 6 km N of Tofua Island in Tonga. It is elongated NNE-SSW and, with the exception of a small flat area on the SSW coast, rises at angles exceeding 35° to the summit, which has a series of small coalescing craters.

4 days ago · The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian's Global Volcanism Program and the US Geological Survey's Volcano Hazards Program. Updated by 2300 UTC every Wednesday and averaging 16 reported volcanoes, this is not a comprehensive list of all eruptions this week, but rather a summary of activity that meet ...
