Accretionary wedges exhibit complex deformation structures, and recent studies suggest a correlation between landward-vergent thrust faults and shallow earthquakes in subduction zones. Sandboxes can simulate the subduction process and exhibit thrusts similar to those observed. This study aims to elucidate the mechanisms controlling fault vergence in accretionary wedges based on numerical sandbox experiments. The synthesis of simulation results with field observations will provide insights into the first-order controls on vergence patterns.
