We establish Morawetz-type estimates for solutions to the elastic wave equation with singular weights of the form |x|-α or |(x,t)|-α. In particular, we show that space-time weights |(x,t)|-α admit stronger singularities and require weaker regularity assumptions on the initial data compared to purely spatial weights |x|-α.
