A harrowing volcanic eruption on Indonesia’s Mount Dukono has left three people dead, sparking a major investigation into safety protocols and unauthorized mountain expeditions. The incident occurred on Friday when the volcano, located on Halmahera island in North Maluku, unexpectedly ejected massive amounts of debris while a group of 20 hikers was navigating the summit. Two Singaporean nationals and one Indonesian hiker lost their lives in the disaster, while the remaining members of the group were eventually evacuated.

Reza Selang, the guide leading the expedition, described the terrifying sequence of events, noting that the mountain had appeared calm moments before the eruption. According to Selang, he was monitoring the group with a drone when the summit suddenly erupted, showering the area with volcanic material. In a desperate attempt to save his clients, Selang and another hiker, Timothy Heng, attempted to rescue a fallen group member. Tragically, a large boulder, estimated to be two meters wide, struck Heng and the injured hiker, killing them instantly. Selang narrowly escaped the same fate, later describing the overwhelming guilt and trauma he has experienced since the incident.

Local authorities have since confirmed that the expedition took place in direct violation of a standing ban. Since mid-April, officials had prohibited climbing within a four-kilometer radius of the crater, citing persistent volcanic activity and numerous minor eruptions. Despite warnings posted at trailheads and through social media, the group proceeded with the ascent. Investigators are now examining whether negligence by tour operators contributed to the tragedy, with police confirming that they have begun questioning those involved in organizing the climb.

As the investigation unfolds, the Indonesian government has moved to permanently secure all entry points to Mount Dukono, warning that future violations will face strict legal sanctions. The incident has reignited a broader debate regarding safety management on Indonesia’s active volcanoes, which are part of the Pacific ‘Ring of Fire’ and frequently attract tourists despite documented risks. For now, the focus remains on the legal proceedings and the recovery of the victims’ families, as the guide faces potential prosecution for his role in the unauthorized trek.
