How to interpret a tsunami alert in Taiwán
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.

Tsunami monitoring in Taiwan: offshore earthquakes and coastal risk
Taiwan lies near the interaction of the Philippine Sea and Eurasian tectonic plates. Strong undersea earthquakes east and south of the island can generate tsunami waves, although not every earthquake causes a tsunami. The severity of any impact depends on seafloor displacement, water depth, coastal shape and local conditions.
How to interpret this monitor
Use the EarthSentra tsunami portal as geographic and historical context, not as an official evacuation alert. An earthquake or a historical tsunami entry does not establish that a warning is currently in force. For immediate decisions, follow Taiwan’s Central Weather Administration and local emergency management authorities. Coastal observations and official advisories are especially important after a major nearby offshore earthquake.
Coastal safety
If you are near the shoreline and experience strong or prolonged shaking, move promptly to higher ground or farther inland without waiting for an online update. Unusual rapid sea withdrawal or a sudden rise in water level may also be a natural warning. Avoid harbors, river mouths and beaches until officials indicate that the danger has passed; several waves may arrive over an extended period.
For regional context, consult Taiwan’s Central Weather Administration, the U.S. Tsunami Warning System and the global tsunami monitor.
