January 15, 2022 Tonga Tsunami

On 2022/01/15, a major explosive eruption from Hunga Tonga-Hunga Ha'apai in Tonga occurred. The volcano had been actively erupting since 20 Dec 2021.

This page provides data from the Deep-ocean Assessment and Reporting of Tsunami (DART®) buoys and processed NOAA/NOS/CO-OPS coastal tide-gauge stations, and two altimeter tracks from the Jason-3 satellite. Files with DART® and tide gauge data contain raw observations, fitted tidal components, and residual tide values. The DART® data are the real-time water level data (in meters) as recorded by the Bottom Pressure Recorder (BPR) in extended-reporting mode containing measurement types of 15 minutes, 1 minute, and 15 seconds. Real-time data were extracted from the National Data Buoy Center. Files with satellite altimeter data contain tracks’ coordinates, raw and filtered sea surface height anomalies (SSHA) and sampled times. A two-level median filter was used to suppress significant spikes not affecting other observations.

Below are links to individual data files under column Data. The columns in those files are as follows: Time is in Julian days from the beginning of the year, Year, Month, Day, Hours, Minutes, Seconds, Raw Observations, Fitted tidal component, and computed residuals in meters water column.
Details on the data processing methods.

The Jason-3 mission Interim Geophysical Data Records (IGDR) are archived and distributed by NCEI's Jason Mission Project with the user's handbook, including information about the Jason-3 satellite, its mission, ground tracks, data, etc.
