2009 L'Aquila earthquake 2009 L'Aquila earthquake The 2009 L'Aquila earthquake occurred in the region of Abruzzo, in central Italy. The main shock occurred at 03:32 CEST (01:32 UTC) on 6 April 2009, and was rated 5.8 or 5.9 on the Richter magnitude scale and 6.3 on the moment magnitude scale; its epicentre was near L'Aquila, the capital of Abruzzo, which together with surrounding villages suffered most damage. There have been several thousand foreshocks and aftershocks since December 2008, more than thirty of which had a Richter magnitude greater than 3.5. The earthquake was felt throughout central Italy; 308 people are known to have
Olancha Earthquake Sequence (2009) and the nearby Owens Valley are common" and that she expected that the ongoing Ridgecrest earthquake sequence would result in aftershocks in the high 4 magnitude range. Connections between earthquake-prone areas and their history of high magnitude shocks have contributed to the latter liquefaction present in the Olancha earthquake sequence in 2009 also assisting with scientific research. In 1872 an earthquake of magnitude 7.4 to 7.9 occurred in Lone Pine is located 37 kilometres north of Olancha. The 1872 Lone Pine earthquake also demonstrated horizontal ground deformation, eventuating to a 350,000 m graben which eventually was filled with water and
