... and frequently. Stress districts with stress direction, regime type and stress value transformation are concentrative zones of strong earthquakes. Stress districts with local stress differentiation but in the homogeneous stress background are the places where strong earthquakes are relatively concentrated...

The current stress tensor exhibits a heterogeneity in its orientations and magnitudes, possibly...

Finally I recommend that whenever available, independent supporting evidence of hydraulic fracturing results be sought...
