TLDR
In this paper, it was shown that about half of the old faults will be oriented approximately perpendicular to the axis of least compressive stress, forming favorable sites for fluid intrusion, and that the fault-plane solutions for such shocks should yield P -axes aligned with the dip of the seismic zone and T-axes parallel to the zone, although circumstances where the axes are interchanged can arise.About:

The Mechanics of Earthquakes and Faulting
TL;DR: The connection between faults and the seismicity generated is governed by the rate and state dependent friction laws -producing distinctive seismic styles of faulting and a gamut of earthquake phenomena including aftershocks, afterslip, earthquake triggering, and slow slip events.

Distribution of stresses in the descending lithosphere from a global survey of focal‐mechanism solutions of mantle earthquakes
Bryan L. Isacks,Peter Molnar +1 more
TL;DR: A region-byregion analysis of 204 reliable focal-mechanism solutions for deep and intermediate-depth earthquakes strongly supports the idea that portions of the lithosphere that descend into the mantle are slablike stress guides that align the earthquake-generating stresses parallel to the inclined seismic zones as mentioned in this paper.

Bending-related faulting and mantle serpentinization at the Middle America trench
TL;DR: It is documented that bending-related faulting of the incoming plate at the Middle America trench creates a pervasive tectonic fabric that cuts across the crust, penetrating deep into the mantle.
Journal ArticleDOI
Metastable mantle phase transformations and deep earthquakes in subducting oceanic lithosphere
TL;DR: In this paper, the authors show that the olivine → spinel transformation should be kinetically hindered in old, cold slabs descending into the transition zone, and that wedge-shaped zones of metastable peridotite probably persist to depths of more than 600 km.

Conduction of Heat in Solids

TL;DR: In this paper, a classic account describes the known exact solutions of problems of heat flow, with detailed discussion of all the most important boundary value problems, including boundary value maximization.

Seismology and the new global tectonics
TL;DR: In this article, a comprehensive study of the observations of seismology provides widely based strong support for the new global tectonics which is founded on the hypotheses of continental drift, sea-floor spreading, transform faults and underthrusting of the lithosphere at island arcs.

Mantle Earthquake Mechanisms and the Sinking of the Lithosphere
Bryan L. Isacks,Peter Molnar +1 more
TL;DR: In this paper, a pull on the portions of plate left at the surface of the Earth's lithosphere was studied. But the authors did not consider the impact of the slabs of the lithosphere on the surface.

Tensional character of earthquake foci beneath the Aleutian Trench with relation to sea-floor spreading
TL;DR: In this paper, the authors examined six Aleutian earthquakes of the decade 1957-1966 and found that the hypocenters of these shocks were uniformly extensional in character with axes of tension aligned normal to the local axis of the trench.
