Tsunami Tracker – live earthquake map and tsunami indicators

The Tsunami Tracker focuses on strong earthquakes and possible tsunami-related indicators. It is designed as a fast overview for users who want to check recent offshore or coastal seismic events.

The map uses recent earthquake feeds and highlights events where a tsunami indicator is present in the source data. This does not replace official warnings, local evacuation orders or emergency instructions.

Use the tracker to understand where strong earthquakes occurred, how large they were, how deep they were and whether the event is marked as potentially tsunami-related.
