Abstract
Tepev Mons is a large volcanic structure of about 250 km in diameter with an elevation of 5 km above the surroundings, located at the southwestern edge of Bell Regio. It is surrounded by a moat with a depth of about 0.5 km. If this moat is considered to be caused by bending of the lithosphere due to the load of the volcano, then elastic bending models give limits for the effective flexural rigidity FR and the effective elastic thickness of the lithosphere L: 2 x 1023 Nm ≲ FR ≲ 3 x 1024 Nm and 30 km ≤ L ≤ 100 km. High flexural rigidities are associated with small depressions and large thicknesses of the lithosphere and vice versa.
