In 1995, NOAA began developing the Deep-ocean Assessment and Reporting of Tsunamis (DART) system. By 2001, an array of six stations had been deployed in the Pacific Ocean. [16] Beginning in 2005, as a result of the tsunami caused by the 2004 Indian Ocean earthquake, plans were announced to add 32 more DART buoys to be operational by mid-2007. [17]
Each DART station consists of a surface buoy and a seafloor bottom pressure recording (BPR) package that detects water pressure changes caused by tsunamis.The surface buoy receives transmitted information from the BPR via an acoustic link and then transmits data to a satellite, which retransmits the data to ground stations for immediate dissemination to NOAA's Tsunami Warning Centers, NOAA's ...
NOAA's GOES-R Series of satellites is designed to improve the forecasts of weather, ocean, and environment by providing faster and more detailed data, real-time images of lightning, and advanced monitoring of solar activities and space weather. GOES-17 can collect three times more data at four times image resolution, and scan the planet five ...
Multiple earthquakes of magnitude 3.0 and higher struck off the west coast in the Pacific Ocean in the early morning hours of Friday, Oct. 18., according to the Pacific Northwest Seismic Center.
The earthquake occurred at 10:44 a.m. with an epicenter under the Pacific Ocean, about 70 miles southwest of Eureka and 110 miles northwest of Mendocino.

A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
The first rudimentary system to alert communities of an impending tsunami was attempted in Hawaii in the 1920s. More advanced systems were developed in the wake of the April 1, 1946 (caused by the 1946 Aleutian Islands earthquake) and May 23, 1960 (caused by the 1960 Valdivia earthquake) tsunamis which caused massive devastation in Hilo, Hawaii.
