In order to improve the reading efficiency of information from command screen and to better carry out earthquake prevention and disaster reduction,a series of studies on the visualization of command screen for seismic information are carried out in this paper. We discuss the visualization content of detailed seismic information on command large screen,including large screen layout,design idea,color matching,text expression,icon design,interactive display and overall display effect.
