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.

Meanwhile, the impact across eastern Indonesia and Timor-Leste has increased after the passage of SEROJA. National authorities in Indonesia report 138 fatalities, 61 missing individuals, and up to 1,114 destroyed or damaged houses across East Nusa Tenggara Province. In Timor-Leste, heavy rainfall that started affecting the country since the end of March, resulted in flash floods and landslides. According to UN OCHA, at least 42 people died and up to 9,779 people have been temporarily displaced in Dili capital city. The International Disaster Charter and Copernicus Emergency Management Service have been activated to support the damage assessment across Timor-Leste. SEROJA is forecast to strengthen as it moves south and could make landfall over Peron Peninsula (central Western Australia) on 11 April, with maximum sustained winds up to 205 km/h. From 10 April, heavy rainfall, strong winds and storm surge have been forecast for the West Coast of Western Australia, between Perth and Coral Bay.
