On 9 September, an eruption started at the Home Reef underwater volcano located in the Tonga archipelago.
As shown in this image acquired by one of the Copernicus Sentinel-2 satellites on 14 September, the eruptive activity formed a new island, approximately 70 metres wide and 10 metres tall.
The new island is more than 90 km away from the nearest inhabited island, so there is currently no danger resulting from the eruptive activity. At the moment, its monitoring relies mainly on satellite images. Find out here how Copernicus contributes to the monitoring of volcanoes located in the most remote places on Earth.
