What determines the size of an earthquake? How can we quantify the control of geometric and material heterogeneities on rupture segmentation? I will present recent progress in our theoretical understanding of earthquake rupture arrest, especially for the largest earthquakes. Recent advances in our group are based on extension of fracture mechanics theory to rupture with large aspect ratio, validated through large-scale 3D simulations as well as reduced 2.5D modeling.
