The effusive eruption at the volcano continues.
Ambrym’s Marum crater seems to be filled with lava from two vents, as seen in the attached time-lapse by NISAR (NASA-ISRO Synthetic Aperture Radar) GSLC (Geocoded Single Look Complex) radar products during the August- October period.
An eruption was reported at Mayon, with the latest observation at 03:50 UTC on 30 October 2026. No ash cloud was identifiable from satellite data at that time.
