What it is Derived, awaiting review
This meta-model describes hazards and what they do: the kinds of hazard and where they can originate, the occurrences that actually happened with their measured intensity and attributed impact, the zones and elements exposed to them, and the alerts issued to people at risk.
Note: First sentence of the legacy card introduction.
Why it exists Filled
Earthquakes, floods, droughts and hazard exposure
Distinguishing features Derived, awaiting review
- It is its own model because a hazard is a standing property of a place while an occurrence is a dated event and an alert is a communication act, and confusing the three is the classic failure of risk data.

Owners Filled
Steward
A hazard monitoring steward maintains the characterization, occurrence and exposure register and an emergency management operator issues and withdraws alerts, each accountable for what it publishes.

What else AI and robots need to interact with it Incomplete
Identity and identifiers required Derived, awaiting review
- hazardType: a kind of hazard; key attributes: identifier, definition, onset speed, typical duration, source classification
Direct properties not applicable Not applicable
Not applicable
Institutional or informational subject: no invented physical properties.
Recognition optional Missing, in the backlog
Not described yet. This gap is in the card backlog.
Capabilities and actions required Derived, awaiting review
- hazardOccurrenceDetected: monitoring or report established that an event was underway
- alertIssued: a graded notice was published for an area with onset, certainty and expiry
- alertUpdated: severity, area or timing of an active notice changed
- alertCancelled: an active notice was withdrawn or allowed to expire
- hazardOccurrenceClosed: the event was declared over and its footprint finalized
- impactAssessmentFiled: attributed damage and affected counts were reported for an occurrence
- exposureZoneRevised: a zone was redrawn after new occurrence data or a new model version
- returnPeriodRecalculated: frequency statistics for a hazard and area were updated with a longer record
Legacy events listed as state transitions.
Hazards and failure modes optional Missing, in the backlog
Not described yet. This gap is in the card backlog.
Standards and interfaces required Derived, awaiting review
- alertFeedContract: terms for redistribution of alerts to broadcasters, applications and neighbouring registers, including no-alteration and timeliness conditions
- exposureContributionContract: terms under which asset registers contribute elements at risk, including grain, refresh and confidentiality limits
- lossReportingContract: terms for reporting attributed impact into the occurrence record, including definitions and revision windows
- sensorAndDetectionFeedContract: terms for real-time detection feeds from monitoring networks operated by others
- publicAlertFeed: current alerts with area, severity and plain-language guidance; omits internal deliberation and contributing sensor diagnostics
- planningHazardZoneMap: zones and return levels for planning use; omits identified elements at risk and their holders
- lossStatisticsSeries: impact totals per occurrence and period; omits per-holder and per-address detail
Context of use required Filled
- Exposure contributions stay owned by the registers that supplied them under S1, disclosure of identified elements at risk happens only through S2 access contracts shaped by S3, and every read is logged in S4.
