9316072 DeMets The PI will participate in a collaborative research program to investigate the rate and direction of motion of the Caribbean and North American plates, as well as the intervening geologic terrains in the northeast Caribbean. The PI and collaborators will reoccupy the sites previously occupied in 1986, and analyze their new data to determine plate and microplate motions during the intervening years. In this way they will obtain new information relating to the driving forces for plate motions, changes in local continental margins and associated sea-level changes, strain partitioning between the plates and microplates, fault slip rates, and seismic hazard along the major fault zones. ****

[9316072] DeMets PI将参与一项合作研究计划，调查加勒比海和北美板块的运动速度和方向，以及东北加勒比海的地质地形。PI和合作者将重新占据1986年以前占据的位置，并分析他们的新数据，以确定在这期间板块和微板块的运动。通过这种方式，他们将获得有关板块运动的驱动力、局部大陆边缘的变化和相关的海平面变化、板块和微板块之间的应变分配、断层滑动率以及主要断裂带的地震危险性的新信息。＊＊＊＊
