This earthquake catalog has 105756 records spanning the time range from 2009 Julian day: 022 to 2010 Julian day: 109. The events were located using phase arrival time data from networks of both moored hydrophones and Ocean-Bottom Seismometers. The data file is in ASCII format, with the following columns: Origin time Year, Julian Day, HR, MN, Sec, tenths Sec, Number stations, Station ID, lat, Long, laterr, Longerr, Origin Time error, Acoustic Magnitude (dB). The data file was generated as part of the projects called Assessment of T-wave Processes and Hydroacoustic Monitoring Capabilities in the Lau Basin, and Continuous acoustic and volcanic debris records of the deepest explosive submarine eruption ever observed. Funding was from NSF awards OCE08-25330, OCE08-25295, OCE08-25424, OCE10-29278, and from the NOAA/PMEL Vents Program.
