Impact verdict

Low impact. LOW: Sources document ongoing explosive and pyroclastic activity at Semeru and a single informal-sector fatality, but provide no evidence of damage to insured commercial or industrial assets, infrastructure loss, or business interruption. The affected zone is a sparsely populated highland area with predominantly artisanal sand-mining exposure, not a concentrated insured property footprint. Potential impact cannot be elevated absent authoritative casualty aggregation, infrastructure damage, or insured-loss figures.
