The NOAA VENTS program has deployed a series of hydrophone arrays in the South Pacific and these arrays have recorded several seismic swarms on the East Pacific Rise. Seismic swarms located at 3 degrees 25 minutes north, at 9 degrees south, and at 22 degrees south are interpreted as magmatic or volcanic. This project will reanalyze the t- phase seismic data and refine the epicenter locations, and then collect a baseline geologic and geophysical data set to ground truth the seismic data.

NOAA风口计划在南太平洋部署了一系列水听器阵列，这些阵列记录了东太平洋隆起上的几个地震群。位于北纬3度25分钟、南纬9度和南纬22度的震群被解释为岩浆或火山。该项目将重新分析t相地震数据并细化震中位置，然后收集一组基线地质和地球物理数据集，以使地震数据真实。
