Research Abstract

In this international project among Japan, China and the United States, we constructed a huge broadband seismic network in the northeastern China. The primary goal of this project is to elucidate the dynamics of the stagnant slab beneath NE China that is originally subducted at the Japan trench islands, as well as the origin of the Chinese continent in the region, but the seismic network can be also used to illuminate the processes occurring in the deepest part of the Earth.
