Geological summary
The small 1.2 x 2.8 km island of Tafahi is a conical stratovolcano about 7 km N of the island of Niuatoputapu in the northern Tonga Islands. It is the northernmost subaerial volcano of the Tofua volcanic arc. The basaltic andesite volcano is elongated N-S, and the summit is located on the SW side of the island. The W side of the volcano is the most dissected, and a narrow fringing reef partially encircles the island. No eruptions have been reported, but its youthful morphology, which resembles that of the larger Kao volcano in the central Tonga Islands, suggests recent activity.
From Wikipedia
Tafahi is a small island in the north of the Tonga archipelago, in fact closer to Savaiʻi (Samoa) than to the main islands of Tonga. It is only 9 km (5.6 mi) north-northeast away from Niuatoputapu, and fishermen commute in small outboard motorboats almost daily between the two. The island has a population of 14.
