9530146 Toomey This project will analyze a seismic data set from natural earthquakes recorded on the Mid-Atlantic Ridge at 35'N. Three- component seismometers collected a set of P and S waves which will be jointly inverted and used to produce three dimensional images of Vp and Vs structure. Anisotropy will be examined from splitting of shear waves. New algorithms will be developed, including ray- tracing routines, inversion of delay-time data, and analysis of anisotropy.

小行星9530146 该项目将分析在北纬35度大西洋中脊记录的自然地震的地震数据集。三分量地震仪收集了一组P波和S波，它们将被联合反演并用于产生Vp和Vs结构的三维图像。各向异性将从剪切波的分裂来考察。将开发新的算法，包括射线追踪程序、延迟时间数据的反演和各向异性分析。
