Source + Feed Reliability Matrix

Each card combines provider provenance, coverage scope, expected cadence, current freshness, and known limits.

Earthquakes Composite

Obsoleto
  • Providers
    USGS, INGV, EMSC
  • Coverage
    Global + Italy regional relevance
  • Cadence
    ~60s dashboard refresh, ingest target <= 10 min
  • Freshness snapshot
    max observed age: 112 min
  • Latency target
    Target freshness: <= 10 min
  • Reliability note
    High when at least two providers are fresh; medium in single-provider fallback.
  • Known limits
    Magnitude revisions and location refinements can appear after first publication.

Volcanoes Activity

Obsoleto
  • Providers
    Smithsonian GVP + observatory channels
  • Coverage
    Global active volcano reports
  • Cadence
    Event-driven + periodic refresh (target <= 20 min)
  • Freshness snapshot
    max observed age: 358 min
  • Latency target
    Target freshness: <= 20 min
  • Reliability note
    High for bulletin-backed activity context; medium for very recent local changes.
  • Known limits
    Observatory reporting cadence is not uniform across regions.

Tsunami Advisories

In ritardo
  • Providers
    NOAA / NWS bulletins
  • Coverage
    Active tsunami watch/warning/advisory regions
  • Cadence
    Bulletin-driven updates (target <= 30 min)
  • Freshness snapshot
    max observed age: 43 min
  • Latency target
    Target freshness: <= 30 min
  • Reliability note
    High for alert-state visibility; requires source bulletin verification for legal decisions.
  • Known limits
    Advisory texts can change quickly during evolving events.

Space Weather

In ritardo
  • Providers
    NOAA SWPC
  • Coverage
    Kp index, storm level, flare context
  • Cadence
    Frequent ingest (target <= 20 min)
  • Freshness snapshot
    max observed age: 43 min
  • Latency target
    Target freshness: <= 20 min
  • Reliability note
    High for operational awareness; medium for short-term forecast certainty.
  • Known limits
    Solar conditions can shift faster than fixed polling windows.

Operational Support Feeds

Obsoleto
  • Providers
    Institutional pages and curated endpoints
  • Coverage
    Bulletins, volcano cams directory, resources support
  • Cadence
    Target <= 30-45 min depending on source
  • Freshness snapshot
    max observed age: 358 min
  • Latency target
    Target freshness: <= 45 min
  • Reliability note
    Medium-high for context, not for immediate hazard detection.
  • Known limits
    Some endpoints are curated and may include temporary unavailability.
