As before I will talk in an expansive BBC fantasy tone, and the pesky physics brackets will correct me.
Middle Earth, for me, is the zone between Japan and New Zealand. The Good Tectonics Guy gave up all thought of clean lines for this area (pure chance). Directly opposite is the Caribbean Giant Thumb, so maybe there is something about the middle.
Anyway ME is a magical place (comon'!). It's the only place I've looked at that has two oceans subducting at each other. Over at India, the oceanic plate jammed the whole subcontinent at Asia, and formed the Himmies, but here, the Indian Ocean thinks it can push around the Pacific.
The two plates dive beneath the earth and cannot give each other a punch in the nose. That's because their feet are too long and meeting on the 'down low'. (subducting plates collide). That whole zone is the bubble-froth of the two plates fighting it out. Will one stay on top? Who knows? Lots of volcanoes and lots of interior earthquakes. We saw the Phil earthquake recently.
This zone is a mess, and you can't predict anything with it. Sorry. However, the inhabitants should expect an earthquake at any time. Again, the return period is a few hundred years at any one spot. This is the worst, as people fall asleep at the switch. If you have a big earthquake every 50 years, that's 'living memory' and you get "Old granpa said put steel in everything.'
- next New Zealand
ps - getting sleepy. I need more people to buy me a coffee.
