On the origin of the North Pacific arcs [PDF]
, 2004 We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean.

Deep Underground Science and Engineering, EarlyView.This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Curie Point Depths of the Amur Tectonic Plate
Russian Journal of Earth SciencesBased on the analysis of the anomaly magnetic field for the Amur Plate and adjacent territories, a Curie Point Depth (CPD) map has been constructed, which we identify with the isotherm 578°C — the temperature of the Curie point of magnetite.

Seismo-tectonics in Fennoscandia
, 1978 Studies of seismic risk in Sweden indicate that there is coherence between the epicentres of earthquakes and the tectonics. On the basis of the existing seismic data and the tectonics, eleven seismo-tectonic zones are suggested for the Fennoscandian ...

Deep Underground Science and Engineering, EarlyView.Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.
