Two lava arms continue to travel over the southern and eastern slopes (image: Sentinel-2)

The effusive eruption at the volcano continues.

The Sentinel-2 thermal imagery reveals that the lava from the summit lava dome branched off into two main arms, advancing over the southern and eastern flanks.
The eastern lava flow appears to be more active and is currently about 1,6 km long. While the southern one shows signs of weaker thermal anomalies has current length of about 1,3 km.
