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.

Affected people: 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

A magnitude 7.7 earthquake struck offshore, about 30 kilometres northeast of Mbay in Indonesia's East Nusa Tenggara Province, on 15 August. BMKG located the epicentre at 8.41°S, 121.39°E and a depth of 15 kilometres. A tsunami warning was lifted later that morning after small waves were observed. By 24 August, national response reporting cited 100 deaths, 1,603 injured people and 180,327 displaced people. Assessments recorded 73,818 damaged homes and 1,915 affected or damaged public facilities. Authorities continued logistics delivery, emergency health support, evacuation management and temporary-shelter operations while aftershocks continued.

BNPB reporting on 15 September revised the disaster-linked death toll to 142: 48 deaths attributed directly to the earthquake and 94 indirect deaths among people in evacuation centres. The same reporting recorded 1,603 injured. BNPB reported 46,461 people still displaced and 103,427 damaged housing units under re-verification; these are September observations and do not replace the preserved 24 August snapshot above. The distinction between direct and evacuation-phase deaths is retained, and the house-damage count remains subject to verification.
