The sequence of events leading up to prominence activation in two different cases is studied. In one case, observed on September 3, 1980, strong velocity shears were produced indicating filament twisting. In the other case, observed on June 22, 1980, activation results in the ejection of prominence material. The paper presents new evidence for a common initial triggering mechanism, the birth or motion of pores at one end of the activated filament sections. This is taken as an indication of emerging magnetic flux and current induction in the filaments. The difference in the final results is partly due to the different ambient magnetic field structures. In particular in the case leading to material ejection there is a subsequent associated flare occurred indicating the storage of magnetic energy in the region. Models are proposed for the two sequences of events, clarifying the underlying similarities and interpreting the distinct features of the two sets of observations.
