The comparison of the volcano’s summit crater before and after the eruption in mid-April this year (image: Sentinel-2)
A rare cloud-free satellite image of the volcano was captured during the latest Sentinel-2 acquisition on September 9th. The image revealed significant morphological changes to the summit crater, which underwent intense paroxysmal episodes in mid-April. The crater has noticeably widened and deepened, as shown in the attached animation comparing it to a cloud-free, pre-eruption image from late January.
Before the eruption, the summit crater had a diameter of approximately 1.57 km with an area of about 0.19 km². After the violent paroxysmal activity, the crater expanded to a diameter of 2.12 km with an area of about 0.28 km².
