Lava flows within the Manaro Voui caldera as seen from space on 27 April (image: Sentinel-2 prrocessed by Martin Kelko)

A new lava flow effusion started within the summit crater since early April.
Satellite images from Sentinel-2 depict a strong thermal anomaly within the Manaro Voui caldera (also called Lombenben Voui), indicating lava flows.
The activity is accompanied by strong steam-laden plumes with minor amounts of ash.
