The small islands of Hunga Tonga (upper right) and Hunga Ha'apai (left) are the peaks a large seamount located about 30 km SSE of Falcon Island. The two islands are about 2 km long. They have inward-facing cliffs that represent the W and N remnants of the rim of a largely-submarine caldera lying E and S of the islands. A shoal is visible 3.2 km SE of Hunga Ha'apai and 3 km south of Hunga Tonga and marks the most prominent historically active vent.
