We establish a new BKM-type blow-up criterion for solutions of the incompressible Euler equations that belong to Sobolev or H" older spaces. Our criterion involves the L2 norm in time of the L^∞ norm of the first order tangential derivatives. Moreover, it applies to various domains such as the full space, the half-space, torus, (in)finite channel, and domains with curved boundaries. Additionally, we provide a mixed criterion involving the L1t L^∞(Ω1) norm of the vorticity and the L2t L^∞(Ω2) norm of the first order conormal derivatives of the velocity where Ω1 ∪ Ω2 = Ω is a suitable decomposition of the physical space. Finally, we prove a blow-up criterion for the class of solutions that belong to the Sobolev conormal spaces that is recently constructed in~\citeAK1.
