Large amount of SO2 concentrations in the atmosphere following the Ambrym volcano on 20 September (image: Sentinel-5P)A new eruption started at the volcano.Based on strong thermal radiation from MODIS satellite imagery and also from ESA's Sentinel-2, it seems that an effusive eruption has been ongoing within the Marum crater since 18 September. Visibility of the new lava flow activity was very limited due to dense cloud cover, but the intense thermal anomaly might indicate lava flows.Thermal radiation from Ambae volcano on 19 September (image: Sentinel-2, credits to Volcano Culture)
