List and filter real-time global natural disasters from the active 24-48 hour monitoring pool. Use to discover ongoing hazards, search by nation, or filter by hazard type or severity level. Do not use if you already possess a specific event_id (use get_disaster_by_id instead) or to evaluate coordinate proximity (use find_disasters_near_coordinates instead). Pure read-only operation with zero side effects. Returns {'matched_count': 0, 'events': []} when no incidents match filter criteria without raising errors.

Retrieve comprehensive technical telemetry, impact metrics, casualty estimates, and exposed infrastructure for a specific disaster ID. Use exclusively when you already hold a valid event_id obtained from list_active_disasters or find_disasters_near_coordinates. Do not use to browse or discover active disasters (use list_active_disasters instead) or for coordinate proximity queries (use find_disasters_near_coordinates instead). Pure read-only lookup. If the requested event_id is not in the active pool, returns an {'error': '...'} JSON object without raising exceptions.

Locate active natural disasters within a radial distance (km) of target latitude and longitude coordinates. Use when evaluating geographic hazard exposure for specific facilities, cities, ports, or data centers at known coordinates. Do not use for country-wide or categorical queries (use list_active_disasters instead) or if you already hold an event_id (use get_disaster_by_id instead). Calculates great-circle distance via Haversine formula. Results are sorted ascending by distance_from_query_km. Returns {'matched_count': 0, 'results': []} if no incidents fall within radius.
