Table 2 Total lava volumes calculated from Pléiades and airborne stereoimages, in response-mode and reanalysis-mode, using the Islands DEM as the pre-eruption DEM. Volumes are expressed in million cubic meters. All the effusion rates are reported as an average since the start of the eruption, defined on 19 Mar 2021, 21:40 local time
