This is a microseismic study of the East Pacific Rise at 9 degrees 50 minutes north to provide constraints on shallow magmatic and hydrothermal processes. The study will locate areas of seismic activity and compare them to seafloor geological features, determine the depth extent of microseismicity to delimit the region of brittle fracture, and test whether the seismicity is migrating along the ridge. Two deployments of ocean-bottom seismometers will be conducted; the first to delineate regions of high microseismicity, and the second to provide for accurate hypocenter locations.

这是东太平洋海隆的一次微震研究， 北纬50度，限制了浅层岩浆 和热液过程。 这项研究将确定地震发生的地区， 活动，并将其与海底地质特征进行比较， 确定微震活动的深度范围，以划定区域 脆性断裂，并测试地震活动是否迁移 沿着山脊。两个海底地震仪的部署将 进行;第一次划定高区域 第二个是提供准确的震源 地点
