Earthquakes, explosions and compression waves – a paper from The Institute of Geophysical Research, Kurchatov, Kazakhstan [in English]
This has info on faults and direction of stress.
“Focal mechanisms of “abnormal explosions” and earthquakes are oblique reverse faults along the planes of north-west or north-east extension corresponding to direction of main fault system direction: Karatayu and Northern Tien Shan.”
And something on strain release energy during quakes. These are all from the nuke watchdog site. But they seem suspiciously like big time nuke promoters.
