Abstract. The faults system mapped in the northern Marche Apennines, the NW sector of Monte Nerone, Italy, shows many indications of recent activity. This area has been affected by some strong historical earthquakes, such as the Cagli earthquake of 1781, similar to seismic events close by affecting the southern Marche, Umbria, Lazio, and Abruzzi areas in recent years, we focused our investigation on this sector. The original field mapping work integrated with seismic and subsurface data suggests very similar genesis and kinematics to those of the recent seismic events in the south of Marche region. In addition, this interpretation could also attest the extensional tectonic activity affecting the whole Adriatic side of the watershed backbone of this sector of the Apennines, with probable inversion of involved previous compressional features, such as thrust ramps.

Monte Nerone 地区的正常断层系统及其在北翁布里亚-马尔凯亚平宁山脉（意大利）近期地震构造环境中的意义

摘要。绘制在意大利蒙特内罗内西北地区马尔凯亚平宁山脉北部的断层系统显示了许多近期活动的迹象。该地区曾受过一些强烈的历史地震的影响，例如 1781 年的卡利地震，类似于近年来影响南部马尔凯、翁布里亚、拉齐奥和阿布鲁齐地区的地震事件，我们将调查重点放在这一领域。与地震和地下数据相结合的原始野外测绘工作表明，其成因和运动学与马尔凯地区南部最近发生的地震事件非常相似。此外，这种解释还可以证明影响亚平宁山脉这一部分分水岭主干的整个亚得里亚海一侧的伸展构造活动，可能与先前的挤压特征发生反转，
