- 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 $L^2$ norm in time of the $L^\infty$ 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 $L^1_t L^\infty(Ω_1)$ norm of the vorticity and the $L^2_t L^\infty(Ω_2)$ norm of the first order conormal derivatives of the velocity where $Ω_1 \cup Ω_2 = Ω$ 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~\cite{AK1}.
