Investigation of Local Seismicity Recorded by the MELT Array

小行星9712176 利用MELT海底地震仪实验的数据，可以对东南太平洋海隆一段沿着300公里长、南纬15至18度、两侧离轴达400公里的地方地震活动进行全面分析。 该实验部署了51个地震仪7个月，并提供了一个机会，以检测构造和岩浆事件和地内地震活动在一个超快速扩展的山脊。 这项研究有两个组成部分。 第一个是确定海脊轴线处和附近的地震活动特点，将地震活动与火山和轴带构造特征沿走向的变化联系起来，并利用地震活动的空间和时间模式来评价海洋地壳形成基本过程的现有模型。 第二部分是评估板内地震活动的水平和性质及其与海底年龄、海山、重力线理或其他构造特征的相关性。

9712176 Shen A comprehensive analysis of the local seismicity along a 300 km-long stretch of the Southern East Pacific Rise, 15 to 18 degrees south, and off-axis out to 400 km on either flank is possible using data from the MELT ocean-bottom seismometer experiment. This experiment deployed 51 seismometers for 7 months, and provides an opportunity to detect tectonic and magmatic events and intraplace seismicity at a super-fast spreading ridge. The study has two components. The first is to characterize seismic activity at and near the ridge axis, to relate seismicity to variations along-strike in volcanic and tectonic features of the axial zone, and to use the spatial and temperal patterns of seismicity to evaluate the existing models of the basic processes of the formation of the ocean crust. The second component is to assess the level and nature of intraplate seismicity and its correlation with seafloor age, seamounts, gravity lineations, or other tectonic features.
