in Geodynamics of the Mediterranean: The Alps and the Apennines
Faults are fractures in the crust that mostranno evidence of movement. The Trocchi undergone a tectonic stress accumulates energy until you reach the breaking point of the rock. The rock can no longer CA storage and energy that behaves in a brittle fracturing and faulting for releasing the stored energy in the form of volume waves (seismic waves). Formed in this way an earthquake. The faulting produces a relative movement of the two three major moving parts:

a fault is said to live when the roof falls from the wall. In this case, the field of the Earth's crust is covered by a relaxing or divergent tectonic regime (eg in the course of a rift). Usually these faults have a plane with an inclination high, around 60 degrees. a reverse fault is called if the roof rises from the wall. In this case the area of \u200b\u200bthe crust is shortened due to a compressive tectonic stress field. The angles of the fault plane are quite bassi (attorno ai 30°). Nel caso di angoli molto bassi o nulli si parla di sovrascorrimenti.
