The earthquake measured 6.2 on the moment magnitude scale and had a maximum Mercalli intensity of VIII (''Severe''). The earthquake was caused by an unknown fault buried under the surface. The shock was felt from the greater Los Angeles Area, north to Susanville in Lassen County, and from the coast east to western Nevada. Through July 31, more than 5,000 aftershocks were recorded, of which 894 had a magnitude of 2.5 or larger. Most of the larger magnitude shocks were felt in Coalinga.〔 ==Earthquake== The Coalinga earthquake was caused by an 0.5-meter uplift of the anticline ridge northeast of Coalinga, but surface faulting was not observed. Ground and aerial searches immediately after the earthquake revealed ground cracks and fissures within about of the instrumental epicenter, none of which appeared to represent movement on deeply rooted fault structures. About five weeks later, on June 11, however, an aftershock caused surface faulting about northwest of Coalinga. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1983 Coalinga earthquake」の詳細全文を読む スポンサード リンク
