High-Resolution Teleseismic Virtual-Source Reverse-Time Migration Imaging of Crustal Structure beneath the Central Tan-Lu Fault Zone, East China

The central Tan-Lu Fault Zone (TLFZ) is located at the eastern edge of the North China Block. The lack of a high-resolution crustal structural model hinders understanding of the uneven earthquake distribution and interactions among tectonic blocks adjacent to the TLFZ. The teleseismic data 'data_evt*.mat' are acquired by two linear seismic arrays crossing the TLFZ in 2008 and 2021, respectively. Another data named 'ImageProfile.mat' is the image results of teleseismic virtual-source reverse-time migration (TV-RTM). We construct a high-resolution seismic reflection profile across the central TLFZ using data from two dense seismic arrays and TV-RTM (Zou et al., 2025). Those data are also partially used by Zou et al. (2022).
