Resonance effect existence or not for landslides triggered by 2008 Wenchuan earthquake: A reply to the comment by Drs. Xu Chong and Xu Xiwei

摘要

We are very grateful to receive these remarks about our paper. In our paper, we found that more landslides occurred in the block located between F2 and F3 than that in the hanging wall of the seismogenic fault of F2 (see Figure 6 in our paper) based on a database of 13,085 landslides in a distributed area of 418.85 km2 (the smallest landslide in this inventory covers an area of 306.5 m2), and we thought that this is maybe the result of resonance of the block between F2 and F3 under the combination movement of the seismogenic faults F2 and F3 and then the motion there is amplified. In their discussion, Xu and Xu (2012) point out that there is no resonance effect of the block between F2 and F3 combination movement, or the resonance effect is rather small based on a more detailed database, with landslides of 197,000 and an area of 1160 km~2.
