WarningAdvisoryWatchThreat messageInformationOfficial forecast and observation pointsTide gauge
Official alert areas are not modelled inundation zones. The source country identifies the earthquake, not necessarily an affected coastline. Historical events and monitoring stations can be toggled separately.
Arrival times at coastal locations
294Expected first arrival according to the published NOAA products, with countdown and in your local time. These are warning-centre forecasts; the first wave is often not the largest, and the threat can last for hours.

Raw data from IOC/UNESCO and NOAA tide gauges, de-tided by QuakeMap24 (moving quadratic fit over ±90 minutes). A signal counts only if the first excursion of at least 5 cm and five times the background noise falls within the physically possible arrival window, the sea level stays clearly more disturbed than before the quake for two hours, and it exceeds anything this gauge showed beforehand. Shown is the largest rise above normal sea level. Noisy or gappy gauges are discarded. Wind, seiches or sensor faults can still mimic signals; official statements take precedence.
