Abstract
The relationship between the subphotospheric flows and flaring activity is not well understood. It is believed that subphotospheric shearing flows play important role in creating unstable magnetic topology that leads to initiation of flares and CMEs. In this paper, we study subphotospheric flows and their relationship with two flares observed in active region NOAA 9393. One of the flares is connected with halo CME. SOHO/MDI and helioseismology data are used for determining the changes in morphology and are compared with changes of the topology as observed by TRACE. We find evidence of some connections between subphotospheric flows within 12 Mm below the photosphere and changes of photospheric magnetic fields and also the flaring activity.
