Geological constraints for a conceptual evolutionary model of the slope deformations affecting Mt. Nuovo at Ischia (Italy) [PDF]

, 2015
ischia island was the scenario of several Holocene slope in- stability events occurred at different scales, from shallow mass movements, triggered by meteo-climatic forcing, up to massive rock slope failures such as large debris avalanches these last ...

A case study on the stability of a big underground powerhouse cavern cut by an interlayer shear zone in the China Baihetan hydropower plant

Deep Underground Science and Engineering, EarlyView.
A 9‐year study on the deformation and stability problem of the large deep underground cavern in Baihetan power station was carried out. Abstract The big underground powerhouse cavern of the China Baihetan hydropower plant is 438 m long, 34 m wide, and 88.7 m high.

Shear deformation of fold structures in coal measure strata and coal-gas outbursts: Constraint and mechanism

Energy Exploration & Exploitation, 2018
The coal measure strata formed in the late Paleozoic era underwent tectonic movements on several occasions, leading to the development of a range of fold structures in the strata as a result of highly interlayered gliding and shearing deformation.

Damage evolution of surrounding sandstone rock under charging–discharging cyclic loading in the natural gas storage of abandoned mines based on the discrete element method

Deep Underground Science and Engineering, EarlyView.
This study established a true triaxial numerical model of rock mass with the discrete element method and explored the crack evolution of surrounding rock of underground roadway gas storage during cyclic loading and unloading and the damage numerical model considering residual deformation.

Episodic Lithospheric Deformation in Eastern Tibet Inferred From Seismic Anisotropy

Geophysical Research Letters, 2020
Mechanisms for uplift and deformation of the Tibetan Plateau remain vigorously debated; hypotheses include stepwise growth, distributed thickening, and crustal channel flow, each with a distinct anisotropic signature.

Seismological structure of the 1.8 Ga Trans-Hudson Orogen of North America [PDF]

, 2016
Precambrian tectonic processes are debated: what was the nature and scale of orogenic events on the younger, hotter, and more ductile Earth? Northern Hudson Bay records the Paleoproterozoic collision between the Western Churchill and Superior plates—the ∼
