How the score is calculated
The score starts at 8. It adds points from recorded affected, deaths, displaced and casualty counts, plus terms found in the story title, event type or status. For each count, only its highest matching band is used.

- 1–999: +5 · 1,000–9,999: +12 · 10,000–99,999: +20 · 100,000–999,999: +28 · 1 million+: +35
- Deaths
- 1–9: +8 · 10–99: +14 · 100–999: +22 · 1,000+: +30
- Displaced people
- 1–9,999: +6 · 10,000–99,999: +12 · 100,000+: +18
- Casualties
- 100 or more: +8
- Story wording
- +10 for terms such as catastrophe, famine, war, conflict, major earthquake, mass casualty or critical. Otherwise, +5 for active, ongoing, emergency, outbreak, cyclone or hurricane.
Score bands: Watch 0–24 · Moderate 25–49 · High 50–74 · Critical 75–100. Scores are capped at 100. Missing or unparseable figures add no points.

Situation
Three fishers disappeared after leaving by speedboat at about 05:30 WIT on 19 September 2026 to check fishing nets around Muara Kali Mooi, Waan district, Merauke regency, South Papua. The initial report named Frederikus Yolmen, Andreas Koboon and Abelbertus Game Yolmen as missing and prompted a joint search by Basarnas Merauke, police, military personnel and local fishers.
Andreas Koboon was recovered deceased on 21 September and Frederikus Yolmen was recovered deceased on 22 September. After seven days of searching, Basarnas Merauke closed the active operation on 27 September following a final evaluation and consultation with the family. Abelbertus Game Yolmen remained missing when the operation closed. The initial three-missing report and the later one-death, two-missing observation remain preserved in the evidence history rather than being silently overwritten.
