Abstract
We present a comparison study of two filament/prominence eruptions driven by helical kink instability. First one, eruptive prominence (EP) on 2010 March 30, is a single magnetic flux rope (FR) that undergoes confined kink induced eruption. The second EP on 2014 May 4 represents kink induced eruptions of two threads of the same filament: the first FR undergoes a confined eruption while the other FR - a full eruption. The physical processes in the EPs environments, such as magnetic emergence, cancellation or shearing, reconnection signatures, overlaying magnetic arcades and the activity events accompanying the eruptions were analyzed. This study laid special emphasis on specific conditions, which are crucial for the type of the filament eruption and its kinematics.
