Measured waves at tide gauges

Own analysis, not official

A tsunami signal was detected at 0 of 1 analysed tide gauges.

Tide gaugeDistanceSignalMax. riseLargest excursionFirst arrivalBackground noise
Ascension
United Kingdom
1,008 kmno signal———1.2 cm

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. Analysed: Oct 28, 2026, 6:16 AM UTC
