Eruption of Lewotobi in Indonesia
Himawari-9 Ash Height product [click to play MP4 animation]
The Lewotobi Laki-laki volcano in Indonesia erupted shortly before 0940 UTC on 17 June 2025 — and the radiometrically-retrieved Ash Height product from the NOAA/CIMSS Volcanic Cloud Monitoring site (above) indicated that ash reached altitudes of 16-18 km.
The corresponding Ash Loading product (below) showed that there were initially high levels of ash loading, which then decreased as the volcanic cloud expanded across the region.

Himawari-9 Ash RGB images created using Geo2Grid(below) revealed that the volcanic cloud was composed of either primarily ash (shades of red), a mixture of ash and SO2 (shades of yellow) or primarily SO2 (shades of cyan).
