National Tsunami Warning Center, NOAA/NWS
Kuril Islands Tsunami of 15 January 2009
A major
earthquake with a moment magnitude of 7.4 (USGS magnitude) occurred at
17:49:39 UTC 15 January 2009 (day 015) and was located 270 miles/432 km south of
Severo-Kuril'sk, Kuril Islands, Russia (46.862N, 155.156E, 22.4mi/36.0km depth--USGS location).
This earthquake produced a tsunami that was recorded at tide gages monitored at
the Tsunami Warning Centers. Many observatories provide data to the centers; such as
the NOAA National Ocean Service, the Japanese Meteorological Agency, 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 arrival computed at the National Tsunami Warning Center (NTWC)
based on the origin time and location. The Sample Interval column shows the
time between samples.
For additional information about these tsunami events see the Pacific Tsunami
Warning Center's homepage .
