Sorry put the wrong link up ...fixed now

Nope it's just normal and a product of humans living in places that are stupid but historically made sense given the geography and abundance of food etc....it's like how towns and cities are situated near rivers that flood.

 

With volcanoes soil is very very fertile so early humans would get bumper crops and be able to grow more livestock etc.

We get plenty in the UK as well but they're deep and of low magnitude

Yeah I know its normal but we definitely been having more higher magnitude ones the last few weeks

6.9 magnitude?

All the ones that happen in the pacific rim and also the ones on the west coast of South America are generally caused by plate tectonics at subduction zone boundaries where the earths crust is colliding with other plates. This is a decent video but note that the speed this happens at in the video will take is sped up very fast and you are watching thousands of years per second. It's not a continuous movement, rather pressure builds up and then something gives way which causes the big earthquakes.

Yep there's been a few this year....apart from the death, destruction and misery it's pretty cool

By the way (you are going to regret opening this topic lol) the trenches at subduction zones are full of mashed up rocks in what's called a 'melange' or mixture, as the plates are pushed down wedges get scraped off and deposited in a accretionary arcs or prisms which fill the deep trenches....if you come here to Anglesey you can see one of the best preserved examples of this in the world

I've been to Iceland and stood between the two plates ... sounds like you know your tectonics nik
