  We propose a mechanism of reheating after inflation in multi-throat scenarios
of warped extra dimensions. Validity of an effective field theory on the
standard model (SM) brane requires that the position of the SM brane during
inflation be different from the position after inflation. The latter is
supposed to be near the tip of the SM throat but the former is not. After
inflation, when the Hubble expansion rate becomes sufficiently low, the SM
brane starts moving towards the tip and eventually oscillates. The SM fields
are excited by the brane motion and the universe is reheated. Since interaction
between the brane position modulus and the SM fields is suppressed only by the
local string scale, the modulus effectively decays into the SM fields.
