Project continues seismologic studies of the thermal regime and dynamics of ocean ridges, the oceanic lithosphere and aesthenosphere. Investigates the relationship between earthquake seismicity, source characteristics to the thermal and mechanical structure of the oceanic lithosphere. Determines the seismic and thermal structure of the crust and mantle below the oceanic ridges and hot spots. Investigates the relationships of earthquake cycles and fault geometry, the state of stress across major fault zones.

该项目继续对洋脊、海洋岩石圈和软流圈的热机制和动力学进行地震学研究。研究了地震活动性、震源特征与海洋岩石圈热力学结构的关系。确定大洋脊和热点下地壳和地幔的地震和热结构。研究地震周期和断层几何形状的关系，主要断裂带的应力状态。
