Seismic stress perturbation and triggering patterns induced by the 2016 Central Italy earthquake sequences

Numerous shallow earthquakes, including 24 th August Amatrice, 26 th October Visso, and 30 th October Norcia earthquakes, ruptured the segments of Mount Vettore-Gorzano fault system in the central Apennines(Italy) in 2016. In order to investigate the stress perturbation and triggering patterns among the earthquake sequences, we introduce a more realistic nonplanar coseismic fault geometry model, which improve the rupture model by assimilating relocated aftershocks and the GPS observations. We adopt the seismic slip inversion program of the steepest descent method(SDM) to create the detailed coseismic rupture models and optimize Coulomb Failure Stress model by varying the coefficient of friction and received fault parameters. The results indicate that the nonplanar fault geometry model is more reflective of the deep slip of the coseismic rupture than planar model. As evidenced by the coseismic Coulomb stress changes caused by the three mainshocks at different depth slices, the stress loading mainly distributes on the active fault zones and the stress changes can well explain the spatial distribution of aftershocks. The first large Amatrice mainshock accelerates the occurrence of the Mw 5.9 Visso and Mw 6.6 Norcia earthquakes, with the positive stress changes at the hypocenter exceeding the stress triggering threshold(0.010×10^(6) Pa) and up to 0.015×10^(6) and 0.257×10^(6) Pa, respectively. Furthermore, the Mw 5.9 Visso earthquake as well encourages the occurrence of the Mw 6.6 Norcia event with the increased stress changes of 0.052×10^(6) Pa on the hypocenter. It is concluded that the stress transfer and accumulation play crucial roles on the linkage triggering mechanism among the mainshock-mainshock and mainshockaftershocks. Noteworthily, the cumulative stress changes on the southwest segment of the Norcia Fault(NF), the southeast parts of the Montereale Fault System(MFS) and Mount Gorzano Fault(MGF) of the main regions are up to(1.5~3.5) ×10^(6) Pa. The cumulative

An Algorithm for Voxelizing Non-manifold Triangle Geometry

引用

科技视界 2018年第4期 82-83,95页

作者： zhang lu-peng JIA Shi-yu WANG Ji-qiang College of Computer Science and Technology Qingdao University

Taking advantage of the characteristic of distance field and octree, we brought up a method which can discrete any triangle-geometry into voxel. As many triangles used for cutting simulation are unoriented, non-manifold or self-intersecting, which leads to ambiguity in mathematical terms. The algorithm firstly computes sign distance field and use the threshold value to reconstruct the surface, which is very close to the original mode. At last, the reconstructed surface is voxelized. Also we can produce voxelized model which is suitable for cutting simulation.
