PANABO CITY (April 28) — Authorities have halted retrieval operations for three men believed trapped in a deep underground tunnel, after conditions at the site were deemed too dangerous for rescuers.
The excavation in Barangay Upper Licanan has been classified as a high-hazard zone, with responders warning that the tunnel—estimated at up to 270 feet deep—poses life-threatening risks, including toxic gas exposure and structural instability.
From rescue to recovery—and now suspension
The operation, initially launched as a search-and-rescue effort, had already shifted to retrieval mode before being suspended on April 25 due to worsening conditions.
Air monitoring inside the tunnel detected ammonia and carbon monoxide, according to the Bureau of Fire Protection, making entry increasingly perilous even for trained responders.
Two bodies have already been recovered:
- A 59-year-old man from Tagum City on April 23
- Another victim, also 59, retrieved the following day
