9618125 Wolfe This project will compare seismic structure at two major hotspots located in contrasting environments; Iceland, a mid-ocean ridge hotspot located on young, thin lithosphere and Hawaii, an intraplate hotspot located on old lithosphere. Regional and teleseismic earthquake data will be used to investigate the effects of hotspot upwellings on lithospheric structure and asthenospheric flow.

小行星9618125 该项目将比较两个主要热点的地震结构，这两个热点位于截然不同的环境中;冰岛是位于年轻薄岩石圈上的洋中脊热点，夏威夷是位于老岩石圈上的板内热点。将利用区域地震和大震资料研究热点上升对岩石圈结构和软流圈流动的影响。
