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, backarc 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 geologic data, zircon age spectra, earthquakes, high resolution crustal to mantle imaging, and Big Data. These new data show the detailed space-time evolution of subduction zones, mountain building, slab stagnation, crustal deformation, continental dynamics, backarc spreading, and other East Asian geodynamics cannot be fully explained by classic theories; 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 this dynamic environment.
