It is believed that subphotospheric shearing flows play important role in creating unstable magnetic topology that leads to initiation of flares and CME. However, the relationship between the flows and flaring activity is not well understood. Using the flow maps obtained by local helioseismology and magnetic and coronal data we attempt to search for this relationship. In particular, we study the evolution of active region NOAA 9393 in the context of changes in magnetic topology and flaring activity. 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.
