Active stress field in central Italy: a revision of deep well data in the Umbria region

Active stress field in central Italy: a revision of deep well data in the Umbria region

In this area the active stress from borehole breakout analysis shows a prevalent NE-SW extension, perpendicular to the main tectonic structures, in agreement with stress inferred from earthquake focal mechanisms and with the strain velocity field. A detailed analysis of active stress data allows to...
