We investigate the interaction between two filaments and the subsequent
filament eruption event observed from different view angles by Hinode, the
Solar and Heliospheric Observatory (SOHO), and the Solar Terrestrial Relations
Observatory (STEREO). In the event, the two filaments rose high, interacted
with each other, and finally were ejected along two different paths. We measure
the bulk-flow velocity using spectroscopic data. We find significant outflows
at the speed of a few hundreds of km/s during the filament eruption, and also
some downflows at a few tens of km/s at the edge of the eruption region in the
late stage of the eruption. The erupting material was composed of plasmas with
a wide temperature range of 10^4-10^6 K. These results shed light on the
filament nature and the coronal dynamics.
