How to interpret a tsunami alert in Argelia
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.

Tsunamis in Algeria: Mediterranean earthquake and coastal hazards
Algeria’s Mediterranean shoreline is exposed to tsunami hazards from certain offshore earthquakes and submarine landslides. The region lies near the boundary between the African and Eurasian plates. One notable historical example is the 2003 Boumerdès earthquake, which generated a tsunami observed across parts of the western Mediterranean.
Reading tsunami information responsibly
Historical records explain what has occurred; they do not indicate that another tsunami is underway. EarthSentra’s monitor is supplementary and should not be used as a substitute for official warnings. For active information, follow Algeria’s civil protection authorities and the Mediterranean tsunami warning and mitigation system coordinated under UNESCO-IOC.
What coastal residents and visitors should know
After severe or prolonged shaking on the coast, head away from the water and towards higher ground as directed by local safety procedures. Tsunami currents can affect harbors and bays even when the waves do not resemble a breaking surf wave. Stay away from the waterfront until authorities provide clearance; the initial surge is not necessarily the largest.
