Fig. 2From: Tonga volcanic eruption and tsunami, January 2022: globally the most significant opportunity to observe an explosive and tsunamigenic submarine eruption since AD 1883 KrakatauChanges in the Hunga Tonga–Hunga Haʻapai volcano over time. Note the subaerial growth during a constructional phase of volcanic activity from 2014 to early 2022. Two separate islands existed on the rim of the caldera in 2014. These were connected by an eruption in 2014–2015, but subsequently disconnected and almost completely destroyed by the explosive eruption on 15 January 2022. The image in the bottom right is from 18 January 2022, three days after the most recent eruption. Credits for satellite images: CNES/Airbus and Maxar TechnologiesBack to article page
