Q hinted in 2527 that the unusual earthquake off Mayotte on Nov 11 may be connected.
As we all know, Q highlighted 11-11 in advance. When asked what happened afterwards (by Freddy!), Q said "Think WAVES / WW" which points at the earthquake (worldwide signature of earthquake waves.)
I don't think anyone here knows what actually happened with that earthquake. But since Q seems to have pointed to it, this remains a very valid subject of investigation.
