Hunga Tonga
Before the 2014–15 eruption, which connected them into a single island, the islands were separated by about 1.6 km (0.99 mi) of ocean water. Before the 2022 eruption, the highest point in the former Hunga Tonga reached an elevation of 149 m (489 ft), while Hunga Haʻapai was only 128 m (420 ft) above sea level. Neither island was large; before they were connected in 2015, each island was about 2 km (1.2 mi) long, with Hunga Tonga being roughly 390,000 m2 (0.15 sq mi) and Hunga Haʻapai being 650,000 m2 (0.25 sq mi) in size. They are much smaller after the 2022 eruption. Neither island was developed due to a lack of an acceptable anchorage, although there were large guano deposits on each island.
