September 29 , 2009 DART Data

On 2009/09/29 at 17:48:10 UTC a magnitude 8.1 earthquake occurred 190 km (120 miles) South of Apia, Samoa. This page will provide you with data collected from the Deep-ocean Assessment and Reporting of Tsunami (DART) buoys. These data files contain raw observations, fitted tidal components, and residual tide values. There are 2 types of data:
1) 15-sec values as recorded by the Bottom Pressure Recorded (BPR) or
2) real-time water level data as recorded by the Bottom Pressure Recorder (BPR) in extended-reporting mode.

If 15-sec data is not available at this time, it may become available after the 2011 field season. We have also provided the computed tides, details on the harmonic tidal analysis results, spectra, and wavelet analysis on 15-sec data files. The source 15-sec data are in pounds per square inch absolute [psia], the tidal analysis is performed on that data, but the tsunami event data here are provided in meters water column using conversion factor of 670.0 mm of water/PSIA. The station's co-ordinates and ocean depths are based on ship measurements at time of BPR deployment. DART data processing description. For event details please visit the 2009 Samoa tsunami event page. If you have questions, please contact haz.info@noaa.gov.
