For infinite-area, geometrically finite surfaces X=Γ2, we prove new omega lower bounds on the local density of resonances D(z) when z lies in a logarithmic neighborhood of the real axis. These lower bounds involve the dimension δ of the limit set of Γ. The first bound is valid when δ>12 and shows logarithmic growth of the number D(z) of resonances at high energy, that is, when |Re(z)|+. The second bound holds for δ>34 and if Γ is an infinite-index subgroup of certain arithmetic groups. In this case we obtain a polynomial lower bound. Both results are in favor of a conjecture of Guillopé and Zworski on the existence of a fractal Weyl law for resonances.
