The Lumajang Regency Government has issued a stern warning to the public, particularly traditional miners, to increase vigilance against latent threats along Mount Semeru's lahar flow paths. This appeal follows a recent workplace accident involving a miner in the area.
Regent of Lumajang, Indah Amperawati, emphasized that volcanic material deposited along riverbeds is not always stable and cool. Much of it still retains high temperatures despite appearing settled on the surface. This condition has the potential to trigger secondary explosions that threaten the safety of anyone working nearby.
"The public should not be fooled by the outer appearance of material piles. Material carried from the mountain slopes can still hold extreme heat for a long duration. The potential for secondary explosions is a real threat that is often overlooked by people operating around Besuk Kobokan," Indah said in Lumajang.
In addition to the latent heat hazard, the Lumajang Regency Government also highlighted increased risks during extreme weather. Heavy rainfall on the peak and slopes poses a risk of re-mobilizing deposited volcanic material, making lahar flow paths highly dangerous zones for mining and other activities.
Indah stressed that disaster mitigation must not focus solely on the eruption phase. Literacy regarding the dangers of residual volcanic material must become part of the community's collective awareness. Her administration pledged to continue intensifying disaster education and safety socializations so that residents can remain productive without ignoring personal safety risks.
