Abstract: We apply the ring diagram technique to source regions of halo coronal massejections CMEs to study changes in acoustic mode parameters before, during,and after the onset of CMEs. We find that CME regions associated with a lowvalue of magnetic flux have line widths smaller than the quiet regions implyinga longer life-time for the oscillation modes. We suggest that this criterionmay be used to forecast the active regions which may trigger CMEs.
