The 1980, 1997 and 1998 Azores earthquakes and its seismotectonic implications [PDF]

, 2007
We have studied the focal mechanisms of the 1980, 1997 and 1998 earthquakes in the Azores region from body-wave inversion of digital GDSN (Global Digital Seismograph Network) and broadband data. For the 1980 and 1998 shocks, we have obtained strike– slip

Optimization method for predicting coal reservoir fractures in the Laochang area of Eastern Yunnan using paleotectonic stress inversion

Frontiers in Earth Science
IntroductionCoal reservoir fractures serve as critical storage spaces and migration pathways for coalbed methane (CBM), significantly influencing CBM enrichment. The characteristics of coal reservoir fracture development can be obtained using traditional

Quaternary rupture of a crustal fault beneath Victoria, British Columbia, Canada [PDF]

, 2017
The seismic potential of crustal faults within the forearc of the northern Cascadia subduction zone in British Columbia has remained elusive, despite the recognition of recent seismic activity on nearby fault systems within the Juan de Fuca Strait.

Lowland river responses to intraplate tectonism and climate forcing quantified with luminescence and cosmogenic 10Be [PDF]

, 2013
Intraplate tectonism has produced large-scale folding that steers regional drainage systems, such as the 1600 km-long Cooper Ck, en route to Australia’s continental depocentre at Lake Eyre.

Up-squeezing of magma under tectonic stress.

Journal of Physics of the Earth, 1989
That some volume of magma could be squeezed up from the magma reservoir triggering a volcanic eruption when compressional tectonic stress is strengthened by plate motion has been proposed as a possible explanation of successive occurrences of volcanic eruption and large earthquake.

Evolution of the overlying strata structure and characteristics of ground pressure behavior under the influence of tectonic stress

Frontiers in Earth Science
The evolution of overlying strata structures significantly influences the manifestation of ground pressure behavior in working faces. The mechanism through which tectonic stress influences the evolution of overlying rock structures remains unclear.

Tectonic stress fields in Northeast Bulgaria

Geologica Balcanica, 1990
The reconstruction of the stress fields in Northeast Bulgaria by means of tectonic fracture patterns and physical anisotropy of rock species from the Lower Cretaceous period up to the Upper Pliocene shows that in the investigated area exists a stable trend towards a clockwise rotati on of the maximum and minimum compress ion axes.
