Abstract
Recent corrections to some of the GONG+ intensity images of flares allow us to image the acoustic power of white light flare signatures. The images clearly show compact regions of white light power at 6 mHz, which are well correlated spatially with the seismic signatures of the flares, when the flare proved to be acoustically active. It has been a puzzle why some of the white light flares, mainly very strong flares, did not induced any seismic waves into the photosphere. We believe that a comparison of the white light spectral hardness of two flares (one seismically active and another one seismically quiet) is the clue to understand the physics of the sun quakes.
