Tectono-Geodynamic Settings in the Conjugation Zone of the Lomonosov Ridge, Eurasian Basin, and Eurasian Continental Margin
AbstractInterpretational analysis of new seismic data allowed us to reconstruct the geodynamic settings that led to the formation of an ensemble of...

Pre-collisional extension of microcontinental terranes by a subduction pulley
Terrane accretion is a ubiquitous process of plate tectonics that delivers fragments of subduction-resistant lithosphere into a subduction zone,...

Oceanic crustal structure and tectonic origin of the southern Kyushu-Palau Ridge in the Philippine Sea
A new high-resolution velocity model of the southern Kyushu-Palau Ridge (KPR) was derived from an active-source wide-angle seismic...

Petrogenesis, U–Pb Age, and Lu–Hf Systematics of Rocks of the Garevka Complex (Northern Yenisei Ridge): Evidence of the Grenville Events at the Western Margin of the Siberian Craton
AbstractIt is established for the first time that biotite plagiogneisses from the Garevka metamorphic complex of the North Yenisei Ridge have...

Crustal underplating and overriding across the collision-subduction transition in the northern Manila subduction zone offshore southwestern Taiwan
The northern South China Sea (SCS) plate between Taiwan and the Philippines experienced complex underplating and overriding. Ocean-bottom...

Thick slab crust with rough basement weakens interplate coupling in the western Nankai Trough
The westernmost Nankai Trough, southwest Japan, exhibits a rapid along-strike reduction in plate coupling in the proximity to the subducting...

Crustal Sinking and Formation of the Main Tectonic Structures and Igneous Provinces in the Arctic in the Late Cretaceous–Cenozoic: A View from the Subduction–Convective Model
AbstractA new geodynamic model of the Cretaceous–Cenozoic evolution of the Arctic has been developed in recent years at the Shirshov Institute of...

Tsunami Modeling in the South American Subduction Zone Inferred from Seismic Coupling and Historical Seismicity
Throughout its history, South America has experienced megathrust earthquakes which have produced large tsunamis, devastating coastal cities in the...

Rapid transition from MORB-type to SSZ-type oceanic crust generation following subduction initiation: insights from the mafic dikes and metamorphic soles in the Pozantı-Karsantı ophiolite, SE Turkey
The Pozantı-Karsantı ophiolite is one of the well-preserved supra-subduction-zone oceanic lithosphere slices. It offers a unique opportunity to study...

The Vp/Vs Kinematic Parameter in the Southern Segment of the Kamchatka Seismic Subduction Zone during the Precursory Period of the March 25, 2020, MW = 7.5 Earthquake and Its Aftershock Process
AbstractThe Vp/Vs kinematic parameter for the Kamchatka seismic subduction zone has been long monitored on a regular basis. This has allowed...

Weakening behavior of the shallow megasplay fault in the Nankai subduction zone
The Nankai Trough megasplay fault hosts diverse modes of fault slip, ranging from slow slip events to megathrust earthquakes, and is responsible for...

Supra-subduction zone mantle peridotites in the Tethyan Ocean (East Anatolian Accretionary Complex–Eastern Turkey): Petrological evidence for melting and melt-rock interaction
The East Anatolian Accretionary Complex formed as a result of the natural process of collision between the Arabian and Eurasian plates and the...

Spatio-temporal distribution of shallow very-low-frequency earthquakes between December 2020 and January 2021 in Kumano-nada, Nankai subduction zone, detected by a permanent seafloor seismic network
We estimate the hypocenter locations and the centroid moment tensor solutions of the shallow very-low-frequency earthquake (sVLFE) activity that...
