Corroborating evidence

Independent live sources scanned for disruption-significant entries about this country. Only strict, disclosed rules count — routine entries are never counted.

meteoalarm-eumetnet1 matching entriesSnapshot
Rule: count the event country's Meteoalarm entry only when its max severity is Severe or Extreme with at least one active warning; Moderate/minor warning loads are routine
- ES — 162 — Severe
viaggia-sicuri-it1 matching entriesSnapshot
Rule: count Viaggiare Sicuri 'ultimi avvisi' entries for the event country ONLY when the item's classified phenomenon (from its free-text title/excerpt) can corroborate the event type — a rail-strike or protest notice does not corroborate a seismic event; the feed only lists destinations with an active alert
