East Asia is one of the most tectonically active regions on Earth and includes the Eurasian continental margin, the western Pacific subduction zones and many of Earth's marginal seas. The region has a long history of subduction, collision, back-arc basin opening and closing, and other plate boundary interactions. In recent years, a wide range of new observations have been collected from the land, oceans and Earth interior, including detailed surface and bedrock geologic observations, earthquake data, high resolution crustal to mantle imaging and Big Data. These new data show that classic theories no long explain the detailed space-time evolution of subduction zones, mountain building, slab stagnation, crustal deformation, continental dynamics, back-arc spreading, and other East Asian geodynamics; new perspectives are needed. Here we seek to share new insights on the geologic history, paleomagnetism, and geophysical character of East Asia since the Paleozoic. We also invite geodynamic models that integrate diverse datasets into a more holistic view of the dynamic environment.
