From: The 2019–2020 volcanic eruption of Late’iki (Metis Shoal), Tonga
Satellite imagery of the 2019–2020 eruption phases. (A–I) Sentinel imagery59 showing the same region before, during and after the October 2019 eruption. Superimposed 100 m contours are from the GMRT grid60 but are not very accurate in this area and are for orientation only. (J–L) MAXAR WorldView-2 and WorldView-3 satellite data of the region showing key events53. Contours are the same as in panels (A–I) but the maps are shown at a different scale. Red arrows in panel K show floating material in the water surrounding the volcano. (M) Drone view of the remains of New Late’iki island on December 3 (taken by Darren Rice of Matafonua Lodge). The island has been reduced to sea level, being continually wave swept and comprises outsized metre-sized blocks of dacitic lava resting on lapilli to ash sized fragmented lava material generated by phreatic explosions. The island is surrounded by an extensive hydrothermal plume.
