Slab dip and trench-parallel curvature controls the trench-normal horizontal seismicity length

The datasets provided include key geophysical data focusing on seismic activity along specific profiles (A-E) and FF (parallel with trench), with each profile corresponding to different sections of the subduction zone. The projection segments include the both dip and age provide critical information on the angle of the subducting plate and its geological age, respectively, which influence seismic behavior along the trench. The suma_seafloor_age dataset provides the age of the seafloor in the region, contributing to understanding the subduction process. The suma_slab2_dep dataset represents the depth of the subducting slab. The suma_slab2_dip dataset gives the dip angle of the subducting plate. The scripts include statistical measures such as Pearson’s r, p-value, slope, and intercept, offering insights into the relationships between these factors and seismic depth. The GCMT Thrust data captures thrust faulting mechanisms along the trench. The USGS Suma2000 data contains earthquake magnitude and focal depth information from 2000 to 2025, providing a comprehensive view of seismicity along the region.
