At the Earth's Core, revisited...

The rankest form of hobbyist's speculation here, as someone who hasn't formally studied geology for forty years, but...

I have to wonder if the (at least since 1996) posited cycles of faster or slower rotation of the inner core of the Earth--in relation to the outer core, mantle and crust/surface--might also result in what (anecdotally, at least) seems to be a current uptick in notable seismic and volcanic activity around the world, including in the last several hours in the border areas in Turkey and Syria and in Buffalo (otherwise, clearly the gods are today targeting the territories English-speakers like to name for fellow chordates)...contrasting firmer data may be useful.
