Late Aftershocks, Tectonic Stress and Dilatancy

Nature, 1973
THE focal mechanisms of micro-aftershocks occurring 3.5 yr after the Inangahua (New Zealand) earthquake of May 23, 1968 (magnitude 7.1), differ drastically from those of the main shock and early aftershocks and are in apparent conflict with the known tectonic stress.

Seismic activation of tectonic stresses by mining

Journal of Seismology, 2013
Hard coal mining in the area of the Bytom Syncline (Upper Silesia Coal Basin, Poland) has been associated with the occurrence of high-energy seismic events (up to 109 J; local magnitude up to 4.0), which have been recorded by the local mining seismological network and regional seismological network. It has been noticed that the strongest seismic events

Tectonic stress field in the Indian subcontinent

Journal of Geophysical Research: Solid Earth, 1992
A map of maximum horizontal compressive stress orientation in the Indian subcontinent has been prepared using orientations derived from three different stress indicators: borehole elongation breakouts, in situ hydraulic fracturing measurements, and earthquake focal mechanisms. Most part of the subcontinent appears to be characterized by a compressional

Mapping Tectonic Stress Using Earthquakes

AIP Conference Proceedings, 2005
An earthquakes occurs when the forces acting on a fault overcome its intrinsic strength and cause it to slip abruptly. Understanding more specifically why earthquakes occur at particular locations and times is complicated because in many cases we do not know what these forces actually are, or indeed what processes ultimately trigger slip.

Stress variability and brittle tectonic structures

Earth-Science Reviews, 2005
The problem of stress variability, both in space and time, during brittle deformation of rocks is faced in this note. Several possible causes of the temporal and spatial variations of the stress tensor are reviewed and discussed. A genetic partitioning of the stress tensor is proposed, showing that any stress field within a crustal volume can be seen ...

Tectonic stress field in East Eurasia

Physics of the Earth and Planetary Interiors, 1983
Abstract The overall pattern of the recent tectonic stress field in the eastern part of the Eurasian plate is inferred from the geological features of large transcurrent and reverse faults, graben structures and from focal mechanism solutions of shallow earthquakes. NE-SW striking trajectory lines, of maximum horizontal tectonic stress axis (σ Hmax),

Tectonic stress distribution of New Zealand

New Zealand is considered as one of the most active earthquake sources in the world, experiencing the deadly 2011 M6.3 at Christchurch, as well as more than 180,000 earthquakes from 1964 to 2016. One important parameter in earthquake statistics is the b value in the frequency magnitude distribution (Gutenberg and Richter, 1954).
