We present a detailed three-dimensional (3D) view of a prominence eruption,
coronal loop expansion, and coronal mass ejections (CMEs) associated with an
M4.4 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 successfully
obtained by the Flare Monitoring Telescope (FMT) following its relocation to
Ica University, Peru. Multiwavelength observation around the H$alpha$ line
enabled us to derive the 3D velocity field of the H$alpha$ prominence
eruption. Features in extreme ultraviolet were also obtained by the Atmospheric
Imager Assembly onboard the {it Solar Dynamic Observatory} and the Extreme
Ultraviolet Imager on board the {it Solar Terrestrial Relations Observatory –
Ahead} satellite. We found that, following collision of the erupted filament
with the coronal magnetic field, some coronal loops began to expand, leading to
the growth of a clear CME. We also discuss the succeeding activities of CME
driven by multiple interactions between the expanding loops and the surrounding
coronal magnetic field.
