Abstract: Let $ M$ be a $ \sigma $-finite, finite von Neumann algebra with a faithful normal tracial state $ \tau $. Let $ \alpha $ be a one-parameter semigroup of normal positive contractions of $ M$. Then it is shown that $ \alpha $ is continuous with respect to the $ {L_p}$-norm $ (1 \leq p < \infty )$ induced by $ \tau $ if and only if it is $ \sigma $-weakly continuous.
