Ripplocations provide a new mechanism for the deformation of phyllosilicates in the lithosphere

Nature Communications, 2019
Phyllosilicate minerals are critical components of seismogenic fault, shear and subduction zones. Here, the authors provide a new deformation mechanism for phyllosilicates, based on newly discovered crystallographic defects in biotite (ripplocations ...

Crustal Thermal Structure and Exhumation Rates in the Southern Alps Near the Central Alpine Fault, New Zealand

Geochemistry, Geophysics, Geosystems, 2020
We investigate orogenic uplift rates and the thermal structure of the crust in the hanging wall of the Alpine Fault, New Zealand, using the hypocenters of 7,719 earthquakes that occurred in the central Southern Alps between late 2008 and early 2017, and ...

Downdip Variations in Megathrust Seismogenic Behavior in the Japan Trench Subduction Zone Affected by Mantle Wedge Serpentinite

Geophysical Research Letters
It is important to seek geological context for the geophysically observed downdip segmentation of seismogenic behavior of subduction megathrusts. Here we focus on how mantle wedge serpentinite may affect megathrust seismogenesis at Japan Trench—an end ...

Seismic risk study based on 3D active fault model of the Ningxia area, northeastern margin of Tibetan plateau

Geoenvironmental Disasters
Background The three-dimensional structural model of active faults are essential for seismic zoning and hazard assessment. Constructing models that accurately represent fault geometry has become a key focus in seismic research. The northeastern margin of

SEISMOGENIC ZONE OF CAPE SHARTLAY (LAKE BAIKAL): SPECIFIC FEATURES OF STRUCTURE, DISPLACEMENTS AND RUPTURE GROWTH

Геодинамика и тектонофизика
Seismogenic deformations of Cape Shartlay represent a very young fault system on the northwestern coast of Lake Baikal. Their study is providing an important opportunity to measure earthquake magnitudes, to identify areas where earthquakes are more ...

Background Seismicity Highlights Tectonic Asperities

Geosciences
The heterogeneity of a tectonic fault interface controls both the spatial features of seismicity and the locations of the foci of shallow earthquakes. Strong earthquakes are associated with ruptures of asperities.
