Mount Merapi, an active volcano in West Sumatra's Tanah Datar District, erupted on 30 May 2026, sending a column of ash approximately 2 kilometres into the air. Authorities have maintained a 3-kilometre exclusion zone around the volcano since a previous eruption in 2023. The eruption underscores the ongoing threat posed by Merapi, one of Indonesia's most active volcanoes, to communities in the surrounding region.
