Fig. 2 - S5P TROPOMI (10.08.2020) - SO2 total column. Ash plumes drifted WNW at 9.8 km high at 14:30 & ENE at 4.3 km high at 16:30.
Fig. 3 - S1 (08.08.2020) - South looking view, the day of the first eruption. Authorities began enforcing a 7-km exclusion zone. There were no fatalities or injuries.
Due to the direction of the erupted material, the different phases of the eruption can only be fully seen by mixing ascending and descending point of views, as it is here. For each of the three couples of image, both ascending and descending views have been acquired on the same date.
