【摘要】 磐安3.5级地震最高烈度为Ⅴ度,等震线形状呈椭圆形,等震线长轴总体呈北东向,Ⅴ度区主要涉及磐安县方前镇、尚湖镇和天台县街头镇。震害特征主要表现在人和器物反映、房屋震害以及地震宏观异常3个方面。通过野外地质调查,断层物质测年等手段,认为奉化—丽水断裂活动时代为中更新世,具备发生中强地震的发震能力,且走向与地震烈度等震线一致。更多还原

【Abstract】 The highest intensity of Pan’an M3.5 earthquake is V, and the isoseismal line is elliptical in shape.The long axis of the isoseismal line is generally northeastwards. The V-degree area mainly involves Fangqian Town, Shanghu Town in Pan’an County and Jietou Town of Tiantai County. The characteristics of earthquake damage are mainly reflected in human and artifacts, house earthquake damage, and seismic macroscopic anomalies. Through the field geological survey, fault material dating and other means, it is believed that the Fenghua-Lishui fault activity era is the Middle Pleistocene, with the ability to generate the middle and strong earthquakes, and the trend is consistent with the the seismic intensity contour.更多还原
