Why Hawaii's volcano is so UNUSUAL

So plates aren't crushing together.

Big friggin magnets are repelling each other from them becoming so big that those striped plates widen (the stripes become one type of magnetic field instead of multiple) for a while causing two like magnetic fields to push apart.

Being they are just fields then, when magma isn't around them they cool. Thus creating wider bands and then they the same band, becomes too wide and pushes itself apart.

Which allows these large magnetic fields to push each other away.
Not plates but magnetic fields that after they separate from each other the magma is allowed to go towards the surface.

Heat destroys magnetic fields. Which is why after the eruption or flow the field collapses along with dirt etc.

You don't notice the void left from the opening because it's so deep and the cooled magma holds everything in place.

But there has to be all these voids with all these spaces that aren't being filled.....unless the magma is like that expanding foam and voila insta earth holder in place...cooled lava for short.

So possible no voids, except where water fills into them then escapes through whatever.

Everything close to the ocean by earth standards has shallower surface which makes it closer, or magma closer to the surface which is under water.
Which causes more frequent eruptions.

Where land mass is more dense (middle of a continent) it's just thicker and therefore not as active as the areas next to the water.

But possibly more violent or could be less violent since the magnetics would create pockets from not being able to push magma all the way to the surface. And therefore creates a denser rock like granite that over time being pushed closer to the surface changes from cooled magma to granite which goes though the same sort of process dinosaur bones go through when found to be stone.
Granite is fossilized magma/volcanic rock.
