We present a detailed three-dimensional (3D) view of a prominence eruption,coronal loop expansion, and coronal mass ejections (CMEs) associated with anM4.4 flare that occurred on 2011 March 8 in the active region NOAA 11165.Full-disk H$\alpha$ images of the flare and filament ejection were successfullyobtained by the Flare Monitoring Telescope (FMT) following its relocation toIca University, Peru. Multiwavelength observation around the H$\alpha$ lineenabled us to derive the 3D velocity field of the H$\alpha$ prominenceeruption. Features in extreme ultraviolet were also obtained by the AtmosphericImager Assembly onboard the {\it Solar Dynamic Observatory} and the ExtremeUltraviolet Imager on board the {\it Solar Terrestrial Relations Observatory -Ahead} satellite. We found that, following collision of the erupted filamentwith the coronal magnetic field, some coronal loops began to expand, leading tothe growth of a clear CME. We also discuss the succeeding activities of CMEdriven by multiple interactions between the expanding loops and the surroundingcoronal magnetic field.
