We study butterfly effect in D-dimensional gravitational theories
containing terms quadratic in Ricci scalar and Ricci tensor. One observes that
due to higher order derivatives in the corresponding equations of motion there
are two butterfly velocities. The velocities are determined by the dimension of
operators whose sources are provided by the metric. The three dimensional TMG
model is also studied where we get two butterfly velocities at generic point of
the moduli space of parameters. At critical point two velocities coincide.Comment: 16 pages, references adde
