2016年8月24日，意大利中部地震（Mw 6.0）后，我们提出了一些关于同震诱发地面破裂的初步结果。干涉合成孔径雷达和地震学数据突出显示，孕震源在两个相邻的结构上破裂：Vettore和Laga断层。我们收集了地面破裂的现场数据沿着整个变形区和两个不同的情况下，故障同震位移从这些观察。向北，沿着山。Vettore断层，表面断层可以沿着一个定义明确的断层链相当连续地映射，而这些功能几乎不存在南部，沿着拉加断层，在那里的夫理石状泥灰岩单位。主要岩性控制了断层的展布，形成了复杂的变形模式。
We present some preliminary results on the mapping of coseismically-induced ground ruptures following the Aug. 24, 2016, Central Italy earthquake (Mw 6.0). The seismogenic source, as highlighted by InSAR and seismological data, ruptured across two adjacent structures: the Mt. Vettore and Laga faults. We collected field data on ground breaks along the whole deformed area and two different scenarios of on-fault coseismic displacement arise from these observations. To the north, along the Mt. Vettore fault, suiface faulting can be mapped quite continuously along a well-defined fault strand while such features are almost absent to the south, along the Laga fault, where flysch-like marly units are present. A major lithological control affects the suiface expression of faulting, resulting in a complex deformation pattern.
