The volcano erupted on 8 May sending ash 10km into the sky and tragically causing the deaths of three hikers and injuring several others who were in the area.

Mount Dukono has been erupting almost continuously since 1933, making it one of Indonesia’s consistently active volcanoes.

There are around 130 active volcanoes in Indonesia which are part of the Pacific Ring of Fire, a 40,000 kilometre horseshoe-shaped region of the Pacific Ocean that contains the majority of the world’s active volcanoes.

EUMETSAT operates the Sentinel-3 satellites, in cooperation with ESA, and delivers the marine and atmospheric data on behalf of the European Union.
