2014年云南鲁甸Mw6.1级地震发生在一个构造和地形复杂的山区，造成了严重的破坏，以及罕见的大规模同震滑坡。由于地表疑似发震断层、余震分布和震源机制解不一致，仍难以确定此次地震的真实的发震断层或发震构造。实际上，这可能意味着震源在深部的复杂性。此外，同震滑坡的分布也表现出一定的扩散性，这与一般情况不同，可能与震源结构有关。
The 2014 Ludian Mw6.1 earthquake in Yunnan occurred in a mountainous area with complex tectonics and topography, which caused serious damage as well as co-seismic landslides of an unusual large scale. Because the suspected seismogenic faults on the surface, distribution of aftershocks and focal mechanism solutions are not consistent, it remains difficult to determine what is the real causal fault or seismogenic structure for this event. Actually, it may imply the complicity of the seismic source at depth. In addition, the distribution of the coseismic landslides also exhibits some diffusion that is different from general cases, likely associated with the seismic focus structure.
