Natural Hazard Event Records — NASA EONET

Keyless. Pay per record. Global natural-event tracking from NASA.

This actor turns NASA's Earth Observatory Natural Event Tracker (EONET) into clean, per-event records — a structured feed of the world's ongoing and historical natural hazards. Each run reads NASA's keyless public EONET API and delivers one row per event: the title and category, whether it is open or closed, the first and last observation dates, the latest position, the reported magnitude, and the primary source that reported it. Event grain, structured for engineering use, in the public domain, with NASA's own fitness disclaimer on every record.

What this is, in one paragraph

EONET is NASA's curated catalogue of natural events — wildfires, severe storms, volcanoes, floods, sea and lake ice, dust and haze, landslides, drought, and more — assembled from many authoritative sources into one consistent metadata layer. This actor reads EONET's events API category by category, de-duplicates events that appear under more than one category, and flattens each event into a single analysis-ready record: identity, category, status, the date range it has been tracked over, its most recent location and magnitude, and the source agency behind it. Values are exactly as served by NASA's public API. You are billed only for records actually delivered.

Who buys this and for what job

• Insurance, reinsurance, and catastrophe modellers building a structured event log of global natural hazards for exposure and loss analysis.
• Climate, environmental, and disaster researchers studying the frequency, distribution, and duration of natural events across categories and years.
• Data engineers and app builders who want a clean, keyed event feed for dashboards and maps without writing an EONET client.
• Supply-chain, logistics, and risk teams watching open events — active storms, wildfires, volcanic activity — near assets and routes.

Public-domain data — with NASA's fitness caveat

Two honesty riders travel on every record. First, licensing: NASA content, including EONET's curated event metadata, is generally not subject to copyright in the United States and is free to reuse — acknowledge NASA as the source. Second, fitness: EONET's own disclaimer states its metadata is intended for visualization and general information only and should not be construed as "official" with regard to spatial or temporal extent — event footprints and timings are drawn from multiple sources and are often approximations. This is not a feed for emergency, navigational, or safety-of-life decisions; verify against the cited primary source before acting.

Event grain — no person data

This actor works at event grain: hazards, categories, dates, locations, and magnitudes. There are no natural-person fields in EONET event metadata, and this actor emits none, with a person-key guard on every record as a backstop.

An unbilled RUN_RECEIPT records the robots check, the category and status, unique events seen and delivered, whether charged equals delivered, and the public-domain / not-official notice.

Field reference

Each record is one event. Identity: record_id / event_id, title, description, and the event link event_link. Classification: category_id, category_title, and categories (all category titles, comma-joined for cross-listed events). State: status (open/closed) and closed_at. Timing and track: date_first, date_last, observation_count, and latest_date. Location and size of the most recent observation: latest_latitude, latest_longitude, latest_geometry_type, magnitude_value, and magnitude_unit. Provenance and caveats: source_ids, source_urls, source, source_url, licence, attribution, disclaimer, and observed_at.

How a run works

A run first re-reads the source host's robots posture from your runtime — EONET's host serves a permissive robots file — and stops at the door if that ever changes. It then reads EONET's events endpoint one category at a time (the combined all-category call is heavy and can transiently error; per-category reads are lighter and retried with backoff), de-duplicates any event listed under more than one category, and flattens each event to a single record: identity, classification, status, date range, latest position, and magnitude. Each record is delivered before it is charged, so a blocked or empty run costs you nothing. Your optional category and status filters bound the pull, and the actor stops at your maxRecords ceiling and records charge_equals_delivered in the receipt.

Categories you can pull

EONET organizes events into a stable set of categories, and this actor surfaces the category on every row so a mixed pull stays self-describing. The categories span the natural-hazard spectrum: Wildfires (by far the largest category), Severe Storms (tropical cyclones and major storms, often with wind-speed magnitudes), Volcanoes, Floods, Sea and Lake Ice (including tracked icebergs), Drought, Dust and Haze, Landslides, Earthquakes, Snow, Temperature Extremes, Water Color, and Manmade events. Pass a single category to build a focused feed — say, only severe storms with their magnitudes — or pull across all categories and group by category_title downstream. Paired with status, you can narrow to just open events (a live hazard monitor) or just closed ones (a historical archive), which is the difference between an operational feed and a research dataset.

Cost guidance

One event_record per delivered event: cost = events delivered × your plan's per-record price. EONET tracks tens of thousands of events across its full history, dominated by wildfires and severe storms, so scope with category and status to keep runs bounded — a single category's open events is typically a few dozen to a few hundred. 1,000 events is $50 (Free) / $33.50 (Gold).

Honest limitations

• Not official. EONET metadata is for visualization and general information; spatial and temporal extents are approximations, not authoritative determinations.
• Not for safety-of-life use. Do not use this feed for emergency, navigational, or evacuation decisions — consult the cited primary source and official warnings.
• Event grain, latest observation. Each record summarizes one event and carries its most recent position and magnitude, plus the tracked date range — not the full geometry track.
• As served. Values are exactly as NASA distributes them; this actor reformats, it does not recompute.
• No person data is emitted.

Differentiation

This actor is the natural-event catalogue angle — global hazards as clean, category-keyed event records from NASA EONET, spanning wildfires, storms, volcanoes, floods, and more. It is distinct from any single-hazard or single-agency feed: EONET's value is the unified, cross-source event layer with a consistent schema, so one pull covers every category at once. The record names its underlying source_ids and source_urls so a buyer who needs the authoritative primary feed for a given event can follow through to it.
