Fig. 1

Each circle represents a block with unique geometric dimensions but identical rock properties (see Section ‘Methods’). The colour of circles indicates the block height. The red line shows the analytical trend predicted by the Euler–Bernoulli beam theory for a cantilever with a rectangular cross section, while the orange crosses show the predicted values considering the Timoshenko–Ehrenfest approximation. The shape of three exemplary blocks, representative of specific simulated scenarios, is reported.
