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 Click Me Load More product (below) showed that there were initially high levels of ash loading, which then decreased as the volcanic cloud expanded across the region.
