About this Research Topic
There has been a big step forward in understanding the geodynamics and tectonics in northeast Asia during the last few decades due to the massive amount of data primarily collected based on land. However, the scope of our understanding of marginal seas in northeast Asia, which hold critical information to understand geodynamics and tectonics of the region, has been limited due to political barriers and difficulties in accessing the study area. Coastal areas in northeast Asia also host multiple mega-cities and major industrial facilities. They are growing in size, and the population burst forth into a new era of urbanization. Consequently, exposures to the submarine geohazards are ever-increasing. Risk/hazard analysis involves understanding many geologic processes. Earthquakes frequently occur below the seafloor. Submarine landslides and tsunamis threaten populations and structures along the coast and offshore. Characterizing submarine geohazards and improving our understanding requires multi-disciplinary and international collaborations.
Although our understanding of offshore tectonics and hazards in northeast Asia is incomplete compared to that onshore, scientists have made significant efforts to advance the knowledge of the region. In this Research Topic in Frontiers in Earth Science, we collect, present and review recent achievements. We believe the collection will serve as an efficient and effective method to promote an open exchange of ideas and information for the scientists as well as engineers and the authorities in national, international governments, and the general public. Toward the end, we would like to propose a new research project involving the deployment of new instruments on the seafloor, additional multichannel seismic profiles across national boundaries, joint interpretations of geophysical data collected on- and offshore, applications of innovative techniques (e.g., ocean bottom seismic networks, artificial intelligence, big data, etc.) and multi-disciplinary sciences to tackle long-standing questions in the region.
This Research Topic aims to gather new ideas, results, and interpretations of the present and developing studies to understand the marginal Seas of northeast Asia for tectonics, submarine mineral resources, and submarine geohazards. Manuscript submissions include, but are not limited to, developments and applications of submarine instruments, data acquisition and processing of multichannel seismic, gravity, and magnetic studies, paleo- and historic submarine earthquakes, monitoring submarine earthquakes, identification of active submarine faults and their potential to generate major earthquakes, submarine landslides, tsunami, risks to the onshore and offshore structures, sedimentary process, paleontology, and paleoenvironment. Multi-disciplinary approaches are highly recommended. Since the purpose of the collection includes fostering marine geologic science in tectonics and submarine geohazards, topics addressing current issues in the field and ideas to make international and/or multi-disciplinary efforts are also highly encouraged to contribute. Potential contributors are encouraged to contact one of the Guest Editors for potential submissions and related inquiries.
