We study the motion of fronts for an extended version of the nonlinear wave equation, ∈2φtt + ∈2γφt = ∈2 Δφ + f (φ) + ∈h + ∈4ηΔφt with positive ∈ ≪ 1 in cartesian and polar coordinates and give a local description of the front in terms of its normal velocity, acceleration and curvature. We study analytically and numerically the motion of planar and circular fronts and perturbations on them.
