Normal‐faulting intraslab earthquakes in the subducted Cocos plate occur as close as 112 km from Mexico City at depths of ∼50–55  km (Fig. 1). The incident wavefield in the Valley of Mexico from these earthquakes is dominated by body waves (Furumura and Singh, 2002). The stress drops of these earthquakes are relatively large (García et al., 2004). In contrast, interplate earthquakes affecting the city occur along the Pacific coast of Mexico at distances greater than about 300 km and at shallower depth (∼15–20  km), and they involve lower stress drops relative to intraslab earthquakes...
