Kink oscillations, which are frequently observed in coronal loops andprominences, are often accompanied by extreme-ultraviolet (EUV) waves. However,much more needs to be explored regarding the causal relationships between kinkoscillations and EUV waves. In this article, we report the simultaneousdetection of kink oscillations and EUV waves that are both associated with anX2.1 flare on 2023 March 03 (SOL2023-03-03T17:39). The kink oscillations, whichare almost perpendicular to the axes of loop-like structures, are observed inthree coronal loops and one prominence. One short loop shows in-phaseoscillation within the same period of 5.2 minutes at three positions. Thisoscillation could be triggered by the pushing of an expanding loop andinterpreted as the standing kink wave. Time lags are found between the kinkoscillations of the short loop and two long loops, suggesting that the kinkwave travels in different loops. The kink oscillations of one long loop and theprominence are possibly driven by the disturbance of the CME, and that ofanother long loop might be attributed to the interaction of the EUV wave. Theonset time of the kink oscillation of the short loop is nearly same as thebeginning of an EUV wave. This fact demonstrates that they are almostsimultaneous. The EUV wave is most likely excited by the expanding loopstructure and shows two components. The leading component is a fast coronalwave, and the trailing one could be due to the stretching magnetic field lines.
