Booker 9418401 The PI has suggested that crustal seismicity in the Pugen Lowland is largely controlled by the deformation properties of material below the volcanic basement and that this sub-volcanic basement may be fluid-bearing and hence electrically conductive. To test this hypothesis he has collected 20 magnetotelluric (MT) and 10 magnetovariation (MV) sites. With current funding, he expects to collect 5 mare MT sites and 10 more MV sites. The MT data appear consistent with the hypothesis, but higher resolution will be achieved when new seismic results are used to provide structural constraints. When combined with earlier data, the MV data will beused to test whether large-scale three-dimensional effects are distorting the interpretation. Funds will support completion of the analysis. ****

Booker 9418401 PI提出，普根低地的地壳地震活动主要受火山基底以下物质变形特性的控制，这种次火山基底可能含有流体，因此具有导电性。 为了验证这一假设，他收集了20个大地电磁（MT）和10个磁变（MV）站点。 在目前的资金支持下，他预计将收集5个mare MT站点和10个MV站点。 MT数据似乎与假设一致，但当使用新的地震结果来提供结构约束时，将实现更高的分辨率。 当与早期数据结合时，MV数据将被用来测试大尺度三维效应是否扭曲了解释。 资金将用于支持完成分析。 ****
