A sand miner sustained severe burns on Saturday after being struck by superheated volcanic material during an eruption of Mount Semeru in Indonesia’s East Java province. The 33-year-old victim, Very Irawan, suffered burns to approximately 80% of his body and remains in hospital for intensive care, according to local media reports.
Incident Details and Volcanic Activity
The eruption lasted approximately four minutes and produced pyroclastic flows, which are fast-moving avalanches consisting of hot gas, ash, and rock fragments. Mukdas Sofian, a volcano observer at the Centre for Volcanology and Geological Hazard Mitigation (PVMBG), confirmed the nature of the volcanic activity occurring at the summit.

Irawan was working with colleagues to collect volcanic sand deposited by previous eruptions when a mass of unstable material collapsed into a river channel. His brother, Aris Susanto, provided this account to Detik.com regarding the circumstances of the incident.
Safety Risks and Mining Operations
Authorities have previously issued warnings against mining in the area surrounding Besuk Kobokan. Indah Amperawati, the head of the Lumajang district, stated that she had appealed to the public to avoid mining activities within a 13-kilometre radius of the south-eastern sector.
Sand mining remains a significant source of income for local communities. The construction industry highly values the sand and stone deposits left behind by the volcano’s regular eruptions, often drawing miners into hazardous zones.
Future Outlook
Given the location of Mount Semeru within the seismically active Pacific “Ring of Fire,” further eruptions are likely. If mining activities continue in restricted areas, residents may face additional risks from sudden pyroclastic flows or material collapses. Future safety efforts could depend on the effectiveness of official warnings and the ability of local authorities to restrict access to hazardous river channels.
