Although its epicentre lay just offshore near Chōshi city, the shallow magnitude 6.1 Mj earthquake produced considerable shaking inland through much of the Bōsō Peninsula and lower Ibaraki Prefecture. It occurred as a result of normal faulting in a seismically quiet region, possibly in response to the magnitude 9.0 Mw 2011 Tōhoku earthquake. ==Effects== Despite its considerable magnitude the earthquake caused only localised light to moderate structural damage in Chiba, owing in part to Japan's advanced earthquake engineering. The most significant effects occurred in Chōshi and Katori cities, where a few walls collapsed and several buildings sustained damage. In Funabashi city an elderly resident suffered a fatal heart attack during the quake, and a falling object caused one minor injury in Kisarazu city. 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「2012 Chiba earthquake」の詳細全文を読む スポンサード リンク
