Using some observational evidences of filament disturbances associated with microflares we point out the following results:
1. The filament destabilization begins at one of its footpoint,
2. Glose to this footpoint one of two pores are observed, they move with an anomalous velocity as seen in white light pictures.
3. Bríghtenings in Hα and in C IV overlie the location of the pores. The pores may be the signature of new emerging flux.
4. The dynamics observed in Hα filament is generally associated with heating of the filament transitíon zone.
5. The excess energy is released at different places along the filament, but this process does not seem to imply a heating conduction front.
