Slab2 model for the Middle America slab in Mexico. Main panel shows a cross-section of Slab2 (blue dot-dashed) vs Slab1.0 in this region (red dashed). The Slab2 model shows a more northeasterly extent to the flat slab than is imaged by earthquake data and focal mechanisms (circles and beachball symbols). Earthquakes and focal mechanisms are colored by depth, according to the scale used in the inset. The location and focal mechanism solution of the September 19, 2017, M7.1 intraplate earthquake near Mexico City is highlighted. The projection width of the cross-section is +/- 50 km.
