The Ocean Acoustic/Marine Geophysics Project of the VENTS Program began continuous monitoring of north Pacific Ocean seismicity in August 1991 using the U.S. Navy's SOund Surveillance System (SOSUS) In May, 1996, monitoring was extended to the eastern equatorial Pacific using moored autonomous hydrophones, then to the North Atlantic in 1999, Antarctic in 2005, Indian Ocean in 2006, and Lau Basin (west Pacific) in 2009. The hydroacoustic method allows detection of low-magnitude seismicity and volcanic activity and provides more accurate source locations than land seismic networks.
