Home Reef volcano grows to 6 hectares (15 acres), Tonga
Home Reef volcano re-emerged above sea level on September 9, 2022, prompting authorities in Tonga to issue a Hazard Alert to all marines to sail at least 5 km (3.1 miles) away from the volcano. The volcano is located midway between Metis Shoal and Late Island in the central Tonga islands. It was first reported active in the mid-19th century when an ephemeral island formed.
