“…35,900 km 2 ) forms a mountainous terrain (28 peaks >3,500 m) at Eurasia's eastern edge. The island's uplift and emergence began in the Early Pliocene, 4–5 Ma, as a consequence of the passive rifted margin of south‐east China being forced into the subduction zone beneath the Luzon Arc on the west‐north‐west advancing Philippine Sea plate (Figure ; Teng, ; Sibuet & Hsu, ; Lallemand, ), the net convergence rate being c . 8 cm/year (Bird, ).…”

“…As continental lithosphere is relatively buoyant (see Ali, ), the Eurasian plate has resisted the downward forcing. As a result, the upper parts of the crust have been squeezed horizontally and now form a stack of thrust‐fault bounded sheets, most of which have north‐north‐west transport directions (Lallemand, ; Teng, ).

Aim Describe the main geo‐physical features of the various sorts of marine islands that are associated with the continents and consider how the ontogenetic pathways of each landmass type might have shaped the hosted biotas. Location Global. Methods Review of the literature that underpins understanding of the “continental” marine islands, particularly those publications with biological, geological, geophysical, oceanographical and palaeoceanographical foci. Results Based on their geo‐physical settings, islands with continental basements/close connections to the continents can be assigned to one of nine categories: shelf, shelf volcano, orogenic margin, continental arc, continental fore‐arc, rifted arc‐raft, isolated raft atoll, isolated block and micro‐continental terrane. As each functions in a distinctive manner, this must have strongly imprinted the native biotas. Main conclusions “Continental” marine islands can be allocated to one of nine groups based on their respective geo‐physical locations. When geological time is considered, then the unique histories of each insular landmass type will have played a critical role in moulding the land‐locked faunal assemblages that have amassed and evolved atop them. Researchers investigating insular biotas, particularly those exploring biodiversity growth, may wish to accommodate these insights.

As an active margin of the Pacific Plate, the ocean‐continent transition zone records major tectonic events from the Late Mesozoic to the present‐day. The development of the transition zone between the Western Pacific Ocean and the East Asian Continental Margin occurred in two stages. In the first stage, the formation of the Songliao and Bohai Bay basins was initiated earlier in the Mesozoic and then the active tectonic events that moved southeastwards to develop the East China Sea and Japan Sea basins in the Cenozoic. We use the methods of tectonics and geophysical analysis for the tectonic reconstruction of the transition zone in the most significant periods of tectonic activity in this area. We propose that the deep processes have a direct influence on the Meso‐Cenozoic surface geomorphologic system in the transition zone. This paper tries to reveal the mechanism of continental margin dynamics by comparing the stratigraphy, sedimentary character and magmatism for each of the four basins, as well as the gravity anomalies, the results of mantle tomography, and thickness of the crust and lithosphere. Our results show that the Songliao and Bohai Bay basins and the East China Sea and Japan Sea basins have similarities in their geomorphological characteristics and sequential tectonic evolution. The Meso‐Cenozoic morphotectonic processes are dominated by the subduction retreat of the (Palaeo‐)Pacific Plate and the eastward tectonic jump. Copyright © 2016 John Wiley & Sons, Ltd.

At the southernmost part of the Ryukyu subduction zone, six long-offset multi-channel seismic profiles were collected across three forearc basins and the southern Ryukyu accretionary prism during the TAIGER experiment in 2009 and the TAICRUST project in 1995. These profiles were reprocessed to generate pre-stack depth migration (PSDM) sections. In addition, two velocity-interface models were obtained by reanalyzing active source data recorded from 28 ocean-bottom seismometers during the same TAIGER experiment, in consideration of the PSDM sections and previous tomography models. Due to the northwest convergence of the Philippine Sea Plate (PSP), it is suggested that the Gagua Ridge may have been obliquely subducting northwestward beneath the Ryukyu prism and below the Nanao Basin. The PSDM sections and the velocity-interface models indicate the subducted Gagua Ridge causing the uplift of the sedimentary basement and the lower crustal structure below the Nanao Basin. The sedimentary and crustal structures near ~ 122.5° E beneath the Nanao Basin were also uplifted where shallow earthquakes had occurred by the oblique subduction of the Gagua Ridge depicted in the isopach map of the crust. Furthermore, a recent earthquake (Mw ~ 6.0) occurred near the northeast coast of Taiwan in 2018 at a depth of approximately 12 km below the Hsincheng Ridge. Our study suggests that this earthquake was caused by a thrust fault near the décollement, which might have been formed by the subduction of the PSP.
