The paper studies the blowup of solutions to the initial boundary value problem for the "bad" Boussinesq-type equation u ttu xxbu xxxx = σ (u) xx , where b > 0 is a real number and σ (s) is a given nonlinear function. By virtue of the energy method and the Fourier transform method, respectively, it
