Mount Semeru, straddling the border of Lumajang and Malang Regencies in East Java, erupted on Wednesday, November 19th. The powerful eruption sent hot cloud avalanches soaring up to 8.5 kilometers from the volcano’s peak, a dramatic display of its destructive force.
The devastating impact of the eruption was acutely felt in three hamlets within Supiturang Village, Pronojiwo District, Lumajang Regency: Kamar A, Sumbersari, and Gumukmas. These communities bore the brunt of the disaster, engulfed and severely damaged by the relentless flow of volcanic material.
During a visit by kumparan to Sumbersari Hamlet on Friday, November 21st, the lingering heat and immediate aftermath were still strikingly evident. Massive chunks of volcanic rock continued to emit smoke, a stark reminder of the recent cataclysm. Our reporters observed that even drops of water would instantly vaporize upon contact with these scorching rocks, and the intense heat was palpable when approaching the smoking debris. Furthermore, the sandy soil, laden with fresh volcanic material, also steamed visibly as a light drizzle fell across the devastated landscape.
Presently, Kamar A and Sumbersari hamlets lie eerily silent and deserted, devoid of any residents. The destructive force of the eruption left a trail of devastation, with numerous homes visibly damaged and volcanic debris still scattered across the abandoned settlements.
