Tornado Sample

This page provides a complete sample response for a tornado hazard from the Active Hazards API endpoint. Tornado hazards can be sourced from multiple agencies including ADINet (ASEAN Disaster Information Network), the U.S. National Weather Service (NWS), and other national disaster management organizations. This particular sample originates from ADINet, which reports disaster events within the ASEAN region with a different property structure than CAP-based weather alerts.

Tornado-Specific Properties

Incident Data

The incident.properties object for this ADINet-sourced tornado provides impact assessment data and location details rather than the standard CAP alert fields. Key incident properties include:

• affectedPersons - Number of individuals affected (e.g., 176)

• fatalities - Number of confirmed fatalities (e.g., 0)

• wounded - Number of injured persons (e.g., 0)

• affectedHouses - Number of houses affected (e.g., 44)

• sourceName - Name of the reporting source (e.g., "ADINet")

• admin0 / admin1 / admin2 - Administrative region hierarchy (e.g., "Indonesia" / "" / "Lampung Selatan")

• sourceUrl - Direct link to the ADINet report page

• event - Event type name (e.g., "Tornadoes")

• hazardName - Full hazard display name (e.g., "Tornadoes - SE of Bandar Lampung, Lampung, Indonesia")

• incidentLocationName - Human-readable location (e.g., "SE of Bandar Lampung, Lampung, Indonesia")

• reportDate / eventDate / effective - ISO 8601 timestamps for the event

• sourceDisclosure - Disclaimer about data preliminary nature

• senderName - Full name of the issuing organization

• missing - Number of missing persons

• iso_code - ISO country code (e.g., "ID")

Features

The features property contains a GeoJSON FeatureCollection with a single exposure area feature. Unlike CAP-based weather alerts, ADINet tornado hazards do not include CAP_INFO features. The feature collection also includes incidentType metadata describing the tornado event type and its associated field mappings.

Exposure Areas

Tornado hazards from ADINet use a single exposure level:

• Level 1: 10km buffer around the reported incident location

Note: Coordinate arrays have been replaced with [...] for brevity. In actual API responses, these contain complete GeoJSON coordinate arrays. The incident.properties and source objects have been truncated with "..." to show only key fields. ADINet tornado hazards include additional impact fields such as settlements, refugees, worshipPlaces, schools, health, bridges, livestock, and various cost/damage fields that are omitted here for brevity.
