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.

- 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
Affected countries: Bosnia and Herzegovina, Czechia, Croatia, Germany, Hungary, Italy, Montenegro, Romania, Slovakia, Slovenia, Serbia, and Austria 3 km from Petrinja, Croatia · 29 Dec, 11:19 A strong earthquake in central Croatia has killed at least seven people, injured more than 20 and caused a significant destruction in Petrinja, a town southeast of the capital Zagreb. Tuesday’s earthquake, which cut phone lines and sent Croatians into a state of shock, was felt throughout the country, neighbouring Serbia, Bosnia and Herzegovina and as far away as the Austrian capital, Vienna. It was the second quake in the area in as many days. Croatian Defence Minister Tomo Medved reported six deaths. “We have a lot of victims. In the vicinity of Glina, in the town of Majske Poljane, five deaths have been confirmed so far. With a girl from Petrinja, a total of six people died in this devastating earthquake,” Medved told reporters in Glina.
