National Data Buoy Center


The National Data Buoy Center (NDBC) is a part of the National Oceanic and Atmospheric Administration's (NOAA) National Weather Service (NWS). NDBC designs, develops, operates, and maintains a network of data collecting buoys and coastal stations.


NDBC’s mission is to provide marine meteorological, oceanographic and geophysical observations accurately and in real-time to assist warning centers, marine forecasters, the military, ocean platform operators and the public.

Pacific Tsunami Warning Center .



The Pacific Tsunami Warning Center (PTWC) is operated by NOAA in the United States. Headquartered in 'Ewa Beach, Hawaii, the PTWC is part of an international tsunami warning system (TWS) program and serves as the operational center for TWS of the Pacific issuing bulletins and warnings to participating members and other nations in the Pacific Ocean area of responsibility. It also monitors the Caribbean Sea & Gulf Of Mexico. As well as being the warning center for the State of Hawaii.


Tsunami Information Bulletin: means that though a threat exists, there is no evidence that a tsunami has been created .


A tsunami advisory means there is a threat of a potential tsunami which may produce strong currents or waves dangerous to those in or near the water. Coastal regions historically prone to damage due to strong currents induced by tsunamis are at the greatest risk.



Tsunami Watch is when the PTWC has determined the earthquake may very likely have created a tsunami and is advising parties to be alert.


Tsunami Warning means the PTWC finds conditions serious enough to issue immediate concern to areas that might be in danger. The message will include approximate arrival times.
