The adjusted Mercalli estimate surface. The adjusted Mercalli estimate surface combines the effect of Mercalli point estimates and support in a collection of sigmoids stretched by intensity. The level of activation is a parameter of our intensity scale. For instance, this surface shows an activation level fixed at Mercalli 6, driving the method towards detecting high energy events
