Tsunami of 17 December, 2016
A major earthquake with a moment magnitude of 7.9 (USGS magnitude) occurred at 10:51:12 UTC 17 December, 2016 (day 352) and was located 90 m/145 km ESE of Rabaul, New Briatin, P.N.G. ( 4.509S, 153.450E, 103.0 km/ 64.4 mi depth -- USGS location).
This earthquake produced a tsunami that was recorded at tide gages monitored by the National Tsunami Warning Center (NTWC).
Many observatories provide data to the centers; such as the NOAA National Ocean Service, the U. of
Hawaii Sea Level Center, the Chilean Navy, the Japan Meteorological Agency and the National Tidal Facility in Australia among others.
Click on the site name to see a graph of the tsunami, when available. Listed wave heights are maximum
amplitude in cm (above sea level). Observed Arrival time is the actual tsunami arrival time in UTC on
gages where it could be determined. The Computed Arrival time is the estimated time of wave arrival
computed at the NTWC based on the earthquake origin time and location. The Sample Interval column shows
the time between data samples.
