How to interpret a tsunami alert in Mexico
Centro de Alerta de Tsunamis de SEMAR (CAT-SEMAR)
The official tsunami threat assessment for Mexico is issued by CAT-SEMAR.
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.
