The ash plume drifted southwest, toward Padang Panjang City. Officials from the Marapi Volcano Observation Post said they await assessments by the Volcanic Ash Advisory Centre Darwin and ASHTAM to determine how far ash may spread.
The ash column appeared gray and thick. Seismic instruments recorded a maximum amplitude of 30.4 millimeters, with the eruption lasting about 38 seconds.
Marapi, standing at 2,891 meters above sea level, was still active when the report was filed.
A resident in Agam, Noviardi, said he was startled by a loud explosion from the volcano that was clearly heard in Baso Subdistrict.

Mount Marapi remains at alert Level II (“Waspada”). The Geological Agency (PVMBG) has issued warnings to avoid activity within a 3-kilometer radius of the Verbeek Crater.
Residents living along rivers originating from the volcano’s summit are especially warned of potential cold lahars (volcanic mudflows), particularly during heavy rain.
Authorities advise wearing masks that cover nose and mouth if caught in ashfall to prevent respiratory issues.
Officials also pointed to the risk of material accumulation from the eruption, which could trigger sudden water flow laden with volcanic debris.
Such hazards are especially dangerous during periods of intense rainfall. The most severe recent comparable event was on May 11, 2024, when lahars claimed dozens of lives in the region.
