Large earthquakes can and do occur repeatedly within short timeframes, as evidenced by empirical observations of seismic clustering and successive megathrust ruptures.
The claim is specific, empirical, and falsifiable regarding earthquake clustering in time. Retrieved papers [1] and [2] provide direct empirical evidence and statistical modeling showing that large earthquakes cluster temporally and that successive major ruptures can occur within short timeframes (e.g., twin ruptures). No papers refute this. Therefore, the verdict is SUPPORTED.
