Several lava flows continue to travel over the southern and eastern slopes (image: Sentinel-2, processed by Martin Kelko)

The elevated effusive eruption at the volcano continues.

The Sentinel-2 satellite acquisition over the volcano on 17 February confirmed that multiple lava flows continue to emerge from the summit cone. descending mainly over the eastern and southern flanks.

The southern branches are currently about 1,79 km long, and the eastern one approx. 2,42 km.
