Since early this year, more and more activities have occurred on the solar disk indicating that we are entering the ascending phase of the solar cycle 24. The active region NOAA 11045 appeared to be incredibly dynamic and produced more than 40 flares above C-class from 2010 February 06 to 14. The Global H-alpha Network (GHN) observed most of these flares from its nine stations world wide with 1 minute cadence and 1 arcsecond pixel resolution. We present the dynamics of filaments during 3 M-class flares on 2010 February 07 and 08. On February 07, we found that the filament shrank after the flare, which could be one of the forms of the "implosion" due to the reduction of the magnetic pressure. Partial eruptions were observed during the February 08 events. Erupted material was found to be cooled and returned to the surface along a filament channel, which was invisible in H-alpha lines prior to the flare.
