Subducted plate geometry, age, and subduction earthquakes beneath Sumatra

The datasets provided include key geophysical data focusing on seismic activity along specific profiles (A-E), with each profile corresponding to different sections of the subduction zone. The Data Frames for 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 correlation results for age and dip include statistical measures such as Pearson’s r, p-value, slope, intercept, R-squared, and standard error, 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.
