2025 July 29, Kamchatka Tsunami Event

NOAA DART®, NOAA/NOS/CO-OPS On 2025 July 29, following a magnitude 8.8 (Mw) earthquake.

This page provides data from the Deep-ocean Assessment and Reporting of Tsunami (DART®) buoys and processed NOAA/National Ocean Service (NOS)/CO-OPS coastal tide-gauge stations. 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 was provided by the National Data Buoy Center. 

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.
