Dataset Information

A Structure from Motion survey was taken of the Yamadu Fault, China in July 2022. Figure 2 shows the Yamadu fault displacement of the piedmont alluvial fan and river terraces. Vertical displacements of ~12.5-15.7 m can be observed on the alluvial fan. Figure 3 shows the Yamadu fault displacement of the piedmont alluvial fan and river terraces. Vertical displacements are ~3.6 m, ~9.1 m and ~15.2 m at the T1, T2 terraces and alluvial fan, respectively.
