Allerte tsunami

Consigli speciali su CAP per gli tsunami

Parametri tsunami strutturati

Un avviso tsunami include idealmente alcune o tutte le seguenti informazioni:
Tempi di arrivo, altezze e località delle onde
- Tempi e altezze devono includere sia i valori previsti sia i valori osservati. Per le altezze, possono essere esatte (ad es. "0,5 m") o un intervallo (ad es. "0,3 m - 0,5 m"). Per gli orari questi devono essere esatti (ad esempio 2012-04-11T17:00:13-07:00).
- Per consentire a Google Public Alert di mostrare orari e altezze di arrivo, i luoghi devono essere indicati come punti con latitudine e longitudine. I nomi delle località devono essere univoci e facili da usare.
Forme di segmenti costieri, che possono essere forniti come file di forma o KML a condizione che il nome geografico sia presente nel file
Risorse rich media come mappe energetiche o mappe dei tempi di percorrenza
Altri formati

Poiché la specifica OASIS CAP non dispone di linee guida su come gli enti avvisi potrebbero fornire informazioni specifiche per tsunami, abbiamo identificato i formati con cui abbiamo lavorato in precedenza e che sono quindi compatibili con Google Public Alert. Contattaci all'indirizzo google-public-alerts@google.com per avere esempi dettagliati.

    <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>
