2009 L'Aquila earthquake concrete elements of the fallen buildings "seemed to have been made poorly, possibly with sand". An official at Italy's Civil Protection Agency, Franco Barberi, said that "in California, an earthquake like this one would not have killed a single person". According to Italian media, L'Aquila's chief prosecutor has opened a probe into possible criminal blame for the collapses. Many people reported seeing peculiar sightings of light glows, flashes, lightning, flames and fireballs, all of which were considered candidates for earthquake light. 241 luminous phenomena were collected including photos and videos. At least 99 of such phenomena occurred before the main
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
