How to interpret a tsunami alert in Australia
Competent national authority
The hub is available, but GDE does not yet have a specific operational national source integrated for this country.
National priority
When an official national assessment exists, it takes priority for that country over regional or international sources.
No inference
EarthSentra does not automatically turn an undersea earthquake or a regional bulletin into a national alert.
In an emergency, follow evacuation orders and official channels from local authorities. EarthSentra is an information service and does not replace official warning systems.
