Shallow seismic activity of the Aeolian islands area is characterized by earthquake Richter magnitudes up to 6. This activity is significantly lower than that which occurred along the E confining zone, ie the S part of the Calabrian arc. Historical and recent instrumental data show a marked difference in the characteristics of the seismicity between the zone located S of the island of Vulcano (gulf of Patti) and W of Lipari and Salina islands. These elements and some previous results on the attenuation of the seismic waves and other medium properties in the Aeolian islands zone lead to explain these experimental data as due to a non-uniform stress field and heterogeneous structure of the crust.

Abstract
Shallow seismic activity of the Aeolian islands area is characterized by earthquake Richter magnitudes up to 6. This activity is significantly lower than that which occurred along the E confining zone, ie the S part of the Calabrian arc. Historical and recent instrumental data show a marked difference in the characteristics of the seismicity between the zone located S of the island of Vulcano (gulf of Patti) and W of Lipari and Salina islands. These elements and some previous results on the attenuation of the seismic waves and other medium properties in the Aeolian islands zone lead to explain these experimental data as due to a non-uniform stress field and heterogeneous structure of the crust.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
