タファヒ島

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.
