The quake’s epicenter was in L'Aquila. The narrow streets of the historic center were filled with rubble, and parked cars were crushed under large blocks of debris. AP Photo/Alessandra Tarantino

Normal Faulting Generalized extensional tectonics ANGELIER J. and COLLETTA B. (1983). - Tension fractures and extensional tectonics. Nature, 301, 5895, p This earthquake in Central Italy (~90 km or 55 miles NE of Rome) occurred as a result of normal faulting on a NW-SE oriented structure in the central Apennines, a mountain belt that runs through Italy. Magnitude 6.3 CENTRAL ITALY Monday, April 06, 2009 at 01:32:42 UTC

The Apennines Mountains o ~ 1,350 km long (the length of the Italian Peninsula) o Formed when the Eurasian and African plates collided o Initially formed as a fold and thrust belt striking NW-SE o Thrusting is no longer active in the Central Appennines o It is experiencing E-W extensional tectonics related to o opening of the Tyrrhenian basin o subducted slab retreat o Includes two active volcanoes (Etna and Vesuvius) Magnitude 6.3 CENTRAL ITALY Monday, April 06, 2009 at 01:32:42 UTC

Historical Seismicity Source: USGS European-Mediterranean Seismological Centre "Around half past 3 a.m. I distinctly felt the bed trembling and the whole house shaking, much like a tree when a strong wind is blowing, and a window opened, too. This happened two times in a short interval, the second time in a stronger and more persistent way: it was 3:34 a.m." Witness location : Latina (107 km / 66 miles from epicenter) Intensity – determined from instrument recordings Magnitude 6.3 CENTRAL ITALY Monday, April 06, 2009 at 01:32:42 UTC

Aftershocks following the Magnitude 6.3 event Multiple significant aftershocks occurred in the hours following the main earthquake. Source: European-Mediterranean Seismological Centre Aftershocks are common following a large earthquake and often hamper rescue efforts that are underway.
