Figure S1. Temperature (a) and pressure (b) versus depth. For the 15–40-km depth range, the parameters of the geotherm are the following: thermal conductivity of 2.4 W m−1 K−1, mantle heat flow of 27.6 × 10−3 W m−2, volumetric radiogenic productivity of 2.8 × 106 W m−3, exponential characteristic length of 8 km, and surface temperature of 288 K.

Figure S2. Strain rate versus depth calculated from equations (1) (dashed red line) and (2) (black line). The force of gravity is the only load.
