Magnitude 7.3 earthquake off the Coast of Fukushima Prefecture

My guess would be that ice melting in the caps triggers a release tension cascade in several parts of the crust, but is just a feeling. Less weight in the poles could make the planet tend to go more "sphaerical".

Just my own stupid theory. I'm not a geologist and could be wrong by a mile.

In any case since several years ago I have noticed a sort of end of the winter pattern: Eyjafjallajökull (2010), Fukushima (2011), Villarica Chile (2015), Fagradalsfjall (2021), New Zealand earthquakes (2022)... all in March.

And then is a waterfall later travelling towards equator: Volcan de Fuego Guatemala (may 2012). Feels a little like a tennis play with eruption waves bouncing, but maybe I'm just cherry picking facts together.

Interesting theory, but wouldn't the ice only melt at one pole cap at a time?

Good point. Dunno. Antarctic and Arctic are very different in terms of Geology. First is a continent with mountains. This means that has a thick crust. North Pole is submerged with some Islands around. Crust here is more thin and should be more prone to move when you remove weight or apply forces in any other direction.
