SUMMARY We present a new 2‐D analytical solution of the fourth‐order differential equation, which describes the flexure of a thin elastic plate. The new analytical solution allows the differential equation for an elastic plate to be solved for any irregular shaped topography with a high spatial resolution. We apply the new method to the Central Andes. The flexural rigidity distribution calculated by this technique correlates well with tectonic units and the location of fault zones, for example, the Central Andean Gravity High correlates with the presence of a rigid, high‐density body.
