Ash movement is estimated towards the east at 25 knots, with the latest advisory issued at 14:33 UTC on 26 October 2026.Original VAAC bulletin: continuous low-level eruption as of 26 Oct 2026, 14:33 UTCKilauea (Hawai'i): The interferometric Sentinel-1D pair in VV polarisation of the volcano, acquired on 24 September and 6 October 2026, shows a compact set of concentric fringes confined to the summit caldera, superimposed on broad, long-wavelength phase gradients across the wider scene.The displacement corresponds to 9.8 cm of relative displacement in the satellite line of sight over the 12-day interval. One full colour cycle corresponds to 2.77 cm of displacement in the satellite line of sight. Concentric fringes within the summit caldera indicate a localised deformation source. The broad, long-wavelength colour gradients elsewhere in the scene are consistent with tropospheric delay rather than ground motion, and the speckled areas are decorrelated, mainly over vegetated terrain...26 Oct:The attached time-lapse includes NISAR (NASA-ISRO Synthetic Aperture Radar) GSLC (Geocoded Single Look Complex) and GCOV (Geocoded Polarimetric Covariance) radar products during June-October period within the Halemaʻumaʻu summit crater.Popocatépetl (Central Mexico): Explosive activity continues.
