The link between actual fault rock/structures and multi-mode slip behavior of faults, such as earthquakes, tremors, creep and others is controversial.

Abstract
The link between actual fault rock/structures and multi-mode slip behavior of faults, such as earthquakes, tremors, creep and others is controversial. We addressed this topic for carbonate-hosted, mature faults carrying out field and microstructural analyses and performing friction experiments on three thrusts exposed in the Umbria-Marche Apennines (Central Italy). Geological observations and mechanical data are in good agreement, suggesting heterogeneous faults characterized by patches with strong materials and localized deformation surrounded by weak materials with distributed deformation. © Società Geologica Italiana, Roma 2013.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
