Abstract: A detailed magnetoseismic analysis of the active region AR10720 on 15 January 2005 is presented. The X1.2 solar flare generated the most powerful seismic emission discovered to date. We study the configuration of the l-o-s magnetic field lines in the quaked area, using extrapolations of the photospheric magnetic field (Sudol & Harvey 2005). Temporal properties of the 6 mHz egression power maps in the area of interest are also analysed. We then describe a number of mechanisms believed to trigger a seismic source during a flare and discuss the likelihood that one of these would generate a sunquake. For this particular sunquake the McClymont effect does not seem to explain the high seismicity of the region.
