Alertes de tsunami

Recommandations spéciales sur la CAP pour les tsunamis

Paramètres structurés du tsunami

Une alerte de tsunami doit idéalement inclure certaines ou toutes les informations suivantes:

  • Heures d'arrivée, hauteurs et emplacements des vagues
    • Les heures et les hauteurs doivent inclure à la fois les valeurs prédites et les valeurs observées. Pour les hauteurs, il peut s'agir d'une valeur exacte (par exemple, "0,5 m") ou d'une plage (par exemple, "0,3 m à 0,5 m"). Pour les heures, elles doivent être exactes (par exemple, 2012-04-11T17:00:13-07:00).
    • Les lieux doivent être indiqués sous forme de points avec une latitude et une longitude pour que les alertes publiques Google affichent les heures et les hauteurs d'arrivée. Les noms des lieux doivent être uniques et faciles à utiliser.
  • Formes de segments côtiers, qui peuvent être fournies au format de fichier de forme ou KML tant que le nom de géocodage figure dans le fichier
  • Ressources multimédias riches, telles que des cartes énergétiques ou des cartes de temps de trajet

Autres formats

Étant donné que la spécification OASIS CAP ne contient pas de consignes sur la manière dont les émetteurs d'alertes doivent fournir des informations spécifiques aux tsunamis, nous avons identifié des formats que nous avons déjà utilisés et qui sont donc compatibles avec les alertes publiques Google. Pour obtenir des exemples détaillés, veuillez nous contacter à l'adresse google-public-alerts@google.com.

    <description>The tsunami Advisory remains in effect for the coastal areas of California from San Onofre State Beach, California (45 miles SE of L.A.) to Ragged Point, California (50 miles NW of San Luis Obispo). - Event details: Preliminary magnitude 8.3 (MWP) earthquake / Lat: -31.500, Lon: -72.000 at 2015-09-16T22:54:31 UTC Tsunami advisories mean that a tsunami capable of producing strong currents or waves dangerous to people in or very near the water is expected.  Significant widespread inundation is not expected for areas under an advisory.  Currents may be hazardous to swimmers, boats, and coastal structures and may continue for several hours after the initial wave arrival. </description>
    <instruction>  If you are in an advisory area - move off the beach and out of harbors and marinas.  Widespread inundation of land is not expected for advisory areas.   Be alert to instructions from your local emergency officials.   Do not go to the coast to observe the tsunami.   Do not return to the coast until local emergency officials indicate it is safe to do so.Next update and additional information:   This message will be updated in 60 minutes or sooner if the situation warrants.   The tsunami message will remain in effect until further notice.   Refer to the internet site ntwc.arh.noaa.gov for more information.</instruction>
