Warning Center, NOAA/NWS
TSUNAMI of 11 March, 2011
(Honshu, Japan)
A
great earthquake with a moment magnitude of 9.0 (USGS magnitude) occurred at
05:46:23 UTC 11 March 2011 (day 070) and was located 80 miles/129 km E of
Sendai, Honshu, Japan (38.322N, 142.369E, 19.9 mi/32 km 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, 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.
For additional information about this tsunami event see the Pacific Tsunami Warning
Center's homepage.
