Modelling of earthquake swarms suggests magmatic fluids in the upper crust beneath the Eger Rift

Communications Earth & Environment
Earthquake swarms are enigmatic seismic phenomena that occur across diverse tectonic settings, from volcanic to intraplate regions, and are often associated with fluid migration, magmatic activity, or stress redistribution. The Northwest Bohemia/Vogtland

Coseismic crustal seismic velocity changes associated with the 2024 MW 7.5 Noto earthquake, Japan

Earth, Planets and Space
The 2024 $$\hbox {M}_{\textrm{w}}$$ M w 7.5 Noto earthquake, Japan, was preceded by an intense seismic swarm thought to be driven by upward fluid migration.

Tectonic Inversion of the SCS from 3-D Magnetization Vector Clustering: Evidence for Differential Rotation and Ridge Jump

Applied Sciences
The eastern and southwestern sub-basins of the South China Sea (SCS) display starkly contrasting magnetic lineation patterns, yet quantitative 3-D mapping of the subsurface magnetic architecture—essential for deciphering basin evolution—remains ...

Stress field in northeastern Japan and its relationship with faults of recent earthquakes

Earth, Planets and Space
Inversion tectonics, in which old normal faults act as reverse faults in current stress fields, are frequently observed in northeastern Japan (Tohoku District); however, the conditions that control these fault activities remain unclear.

Fine slab structure and mechanism of deep earthquakes beneath central Japan

Communications Earth & Environment
Deep-focus earthquakes (> 300 km depth) are widely distributed in global subduction zones, but their mechanism is still debated because the fine structure of deep subducting slabs is unclear.

Earthquakes and earthquake engineering in China

Bulletin of the New Zealand Society for Earthquake Engineering, 1987
China is one of the most earthquake-prone countries in the world and has suffered many disasters. During the last twenty years, especially since the Tangshan earthquake of July 1976 which killed 242,000 people and disabled almost 200,000 people, the Chinese government and the whole society have paid more attention to and made a huge effort to deal with

Coseismic slip distribution of the 2024 Noto Peninsula earthquake deduced from dense global navigation satellite system network and interferometric synthetic aperture radar data: effect of assumed dip angle

Earth, Planets and Space
The Mw 7.5 Noto Peninsula earthquake, which occurred on January 1, 2024, was considerably hazardous to the peninsula and surrounding regions owing to a strong motion, large-scale crustal deformation, and subsequent tsunami.
