Tsunami EventsMarch 2011 Japan earthquake and tsunamiThe March 11, 2011 earthquake occurred off the east coast of Honshu, Japan with a magnitude of 9.0. A tsunami was generated which was recorded throughout the Pacific Ocean. CDIP's Scripps Pier pressure sensor showed the tsunami signal arriving at Scripps at approximately 08:50 PST on March 11. Preliminary analysis shows the tsunami arriving with an amplitude of of over 30 cm and a period of 36 minutes. Official NOAA tsunami record from Scripps Tide Station

February 2010 Chile earthquake and tsunami (Not recorded by CDIP)2010 Chile earthquake occurred off the coast of the Maule Region of Chile on February 27, 2010, 06:34 UTC, rating a magnitude of 8.8 on the moment magnitude scale and lasting for about three minutes. A tsunami was generated which was recorded throughout the Pacific Ocean. The CDIP Scripps pier pressure sensor was undergoing maintenance at the time and did not record the event. However, the NOAA tide guage also located on the pier did record it. 
The plot shows first arrival just about at noon, with the wave train still continuing as of 3pm. Maximum amplitude appears to be about 1 foot and period between 20 and 30 minutes.

September 2009 Samoa Islands earthquake and tsunamiAt 17:48 UTC on September 29, 2009 an earthquake of magnitude 8.0 occurred south of Samoa, centered at 15.509° S, 172.034° W. A tsunami was generated which was recorded throughout the Pacific Ocean. CDIP's Scripps Pier pressure sensor picked up the tsunami signal; it arrived at Scripps at approximately 05:00 UTC on September 30.
November 2006 Kuril Islands earthquake and tsunamiAt 11:14 UTC on November 15, 2006 an earthquake of magnitude 8.3 occurred in the Kuril Islands, centered at 46.577° N, 153.247° E. A mild, low-amplitude tsunami was generated which was recorded throughout the Pacific Ocean. CDIP's Scripps Pier pressure sensor picked up the tsunami signal; it arrived at Scripps at approximately 20:50 UTC on November 15.
May 2006 Tonga earthquake and tsunamiAt 15:27 UTC on May 3, 2006 an earthquake of magnitude 7.8 occurred in the South Pacific, centered at 20.03 S, 174.23 W in the Tonga Islands. A very mild, low-amplitude tsunami was generated which was recorded throughout the Pacific Ocean. CDIP's Scripps Pier pressure sensor picked up the tsunami signal; it arrived at Scripps at approximately 02:40 UTC on May 4.
December 2004 Sumatra earthquake and tsunamiThe earthquake occurred at 00:59 UTC on December 26th west of Aceh, Indonesia. It measured 9.0 on the Richter scale, centered at 3.3 S latitude, 95.8 E longitude. (Details of the event's seismology are available from Project IDA.) Although the earthquake and resulting tsunami were generated in the Indian Ocean, the event was of such magnitude that it produced tsunami effects across the globe. These effects were recorded by CDIP sensors in the Pacific at Scripps Pier, California.A pressure sensor measuring water column height was in use at Scripps Pier (Station 073) at the time of the event. For details of the sensor's location and configuration, check the data descriptions below. (More information regarding this event is available through the WC/ATWC.)
October 1994 Shikotan earthquake and tsunamiThe earthquake occurred at 13:23 UTC on October 4 northeast of Hokkaido, Japan. The earthquake measured 8.5 on the Richter scale and its epicenter was at 42.9 N latitude, 147.2 E longitude. CDIP sensors at Kahalui Harbor, Hawaii recorded the resulting tsunami.View full station details and data: 077 079
