Dr. Patricia Gregg is awarded an NSF Earth Science Postdoctoral Fellowship to carry out a program of research and education at Lamont-Doherty Earth Observatory, Columbia University. Dr. Gregg will investigate the role that magma injection and dike propagation have on the break up of continents along rift zones. The research goals will be accomplished by examining data from local arrays of seismic stations, GPS networks, and InSAR deformation data. These data will be integrated in computer models that take into account changes like temperature and strength of the rocks with increasing pressure and depth into the crust. The results from this investigation contribute to better understanding of the rift systems and they will help in the assessment of hazards like earthquakes and volcanic eruptions. In addition, Dr. Gregg will work with undergraduate and graduate students in assisting with their mentoring in research projects. This investigation will contribute to a larger international effort.

帕特里夏·格雷格博士被授予NSF地球科学博士后奖学金，在哥伦比亚大学拉蒙特-多尔蒂地球观测站开展研究和教育计划。格雷格博士将调查的作用，岩浆注入和岩脉传播的大陆分裂沿着裂谷带。研究目标将通过检查来自当地地震台站阵列、GPS网络和干涉合成孔径雷达变形数据的数据来实现。这些数据将被整合到计算机模型中，该模型考虑到岩石的温度和强度等随着地壳压力和深度的增加而发生的变化。这次调查的结果有助于更好地了解裂谷系统，并有助于评估地震和火山爆发等灾害。此外，格雷格博士将与本科生和研究生合作，协助他们指导研究项目。这项调查将有助于更大的国际努力。
