We encourage the public to subscribe to notifications of tsunami messages sent by the Pacific Tsunami Warning Center. To determine whether you should subscribe to alerts from PTWC or WCATWC, please refer to our page describing the areas of responsibility served by each tunami warning center.
Tsunami messages from PTWC are available via email through either GovDelivery or ITIC. The ITIC option includes all international PTWC tsunami messages, whereas the GovDelivery option allows you to select messages for the area(s) that interest you (Pacific, Hawaii, or Carribbean). Please note that both services also include options for WC/ATWC tsunami messages and include unsubscribe options for users to manage their subscriptions.
Another related option is the USGS Earthquake Notification Service (ENS), which allows users to receive custom automated earthquake alerts via email or SMS. More email subscription options from third parties are listed on the NWS Subscribe page.
Tsunami messages from PTWC are available via SMS (text message) on mobile phones through either GovDelivery or RANET. GovDelivery's SMS service is open to the public on all U.S. cellular carriers. RANET is only available to emergency managers in select Pacific, Asian, and African countries. Note that there are also various RSS-to-SMS and Email-to-SMS services on the Internet that allow users to receive SMS alerts from RSS feeds or emails.
