Recent Eruption at Mount Marapi
Mount Marapi, an active volcano located in the Agam and Tanah Datar Districts of West Sumatra, Indonesia, erupted on Monday, November 3, 2025. The eruption, which occurred at approximately 10:57 a.m. local time, lasted for about 29 seconds, according to reports from the Volcano Post (PGA) of Mount Marapi. An ash column, observed at approximately 300 meters above the summit, was white to gray in color and thick, tilting toward the southeast.
Ongoing Caution Status and Exclusion Zone
Following the event, Mount Marapi remains at Caution Level II (Alert status). The Center for Volcanology and Geological Hazard Mitigation (PVMBG) has issued several critical recommendations to ensure public safety. These include prohibiting the public, tourists, and visitors from engaging in any activities within a three-kilometer radius of the center of activity, specifically the Verbeek Crater.
Potential Hazards and Public Safety Measures
Authorities have also warned of the potential threat of cold lava flows, particularly for communities residing along rivers that originate from the volcano's summit. This danger is especially acute during periods of rain or the rainy season. In the event of ashfall, residents are advised to wear masks covering their noses and mouths to prevent respiratory tract infections. The PGA and PVMBG continue to monitor the accumulation of volcanic material on the mountain's slopes, which could trigger cold lava floods, a situation that has historically proven dangerous.
Geographical Context of Mount Marapi
Mount Marapi, whose name means 'Mountain of Fire', is recognized as the most active volcano in Sumatra. It is situated in the Padang Highlands and is part of the Pacific 'Ring of Fire', a region known for its significant seismic and volcanic activity. The volcano's unpredictable nature, with eruptions often not preceded by deep magma movement detectable by seismic monitors, makes continuous vigilance essential for nearby communities.
