[QUOTE=Ravager]Yeah, but I suppose Yellowstone erupting would be worse...
Your teacher might be impressed of you mention La Palma at least.

[/QUOTE]
I hope so
It isn't only volcanoes, but also earthquakes. I figured the reasons people move to an area with earthquakes would be the same as the reason they move to areas with volcanoes. Earthquakes is very often found in areas where the tectonic plates meet. I guess the earth there is fertile as well.
Correct me if I'm wrong

I suppose it's fertile earth again, though I'm not sure on that.

Why would it be particularly fertile there? Real question. I have no idea. But I have an irresistable notion that the earth would fall down the crack and so make it infertile. Ridiculous, but it piqued me

That's why I wasn't sure, I have a feeling it's the ash that makes the soil more fertile around volcanos, which obviously wouldn't apply to earthquale zones.
I don't think you cn say someonevolunteers to live in such a place thanks to an effect from an earthquake, they choose to live there, because they can, for whatever reason. Space, Money, Family etc.

I agree Rav.And they stay because they can't move or because it is home? Things like that?

Earthquakes and volcanoes tend to be in the same areas. If there was a volcano, and it exploded, the earth around would get fertile and the volcano would be gone. If the tectonic plates move to much, you get an earhquake.
Now if all that happens in the same area over a period of time, you'd move to an area with earthquakes and fertile earth

Or you'd be smart enough to move to the other side of the world.
@Fiona, And the hope that the catastrophe of an earthquake will not happen to them...or in the case of Japan, that technology may help to protect them.

You might well be right, Fib, and I am not in a position to argue. But the way you put it looks like building a card tower. Too many ifs. Reads like the Holy Blood and the Holy Grail. Might want to put in some evidence for us

I can't prove it. It's was an possibility that came to my mind when I was writing earlier today. I have to hand this in on Tuesday. I'll ask my teacher tomorrow if this is possible.
I know that volcanoes have exploded (Krakatau, or Krakatoa if you like

)
And a volcano rumble when it erupts. This is all I can prove

@ Fib. Not criticising or disagreeing, honestly.
Just a comment on the form of the argument. No offence

@ Fiona: It was not a argument, I just stated what I knew was possible. I was also hoping that someone here knew more about the matter than I do

When the lava from Krakatoa cools, it creates more land for people to live on, it'll take a while but volcanoes are providing as well as destroying...

Fib, I don't know anything about it sadly
I did find this which seems to have some useful links in it, though you might find it a bit patronising. Maybe it will help

and this, which is a report from the discovery channel. That is a tv thing but I cannot vouch for its reliability
Why we choose volcanoes as neighbours
If volcanoes are so dangerous, why, one might ask, do so many people live near them? The answer lies in the soil. Over thousands to millions of years, volcanic materials break down to form some of the most fertile soil on Earth, the cultivation of which has produced abundant food and fostered civilizations. In tropical, rainy regions, the process can take as few as a hundred years. And, given enough rainfall, areas buried with new lava recover quickly enough that re-vegetation can begin less than a year after eruption.
Some of the earliest civilizations – Greek, Etruscan, Roman – settled on the rich, fertile soil in the Mediterranean-Aegean region. In Indonesia, some of the best rice-growing regions are in the shadows of active volcanoes. And in the western United States, many prime agricultural areas have soil that is wholly, or largely, of volcanic origin.
In fact, the Earth's crust, on which we live and depend, is in large part the product of millions of once-active volcanoes, and magma that didn't erupt but cooled below the surface instead.
Volcanic eruptions also give us minerals. Most of the metallic minerals mined in the world – copper, gold, silver, lead and zinc – are associated with magmas found deep within the roots of extinct volcanoes located above subduction zones. Magma provides a ready supply of heat that circulates ore-bearing fluids. These fluids can re-deposit metals in concentrated amounts under the right temperature and pressure conditions.
Volcanoes, each with their own personalities and patterns of behaviour, may pose catastrophic dangers, but they also have some valuable qualities to share with their human neighbours.

@ Fiona: Thanks!

That last bit gave me more stuff to write as to why we choose to live next to them.

I think Obsidian is a volcanic by-product too...a rock formed by intense heat.
This one is linked to why people live in eartquake zones...

It was good, kind of boring at the end, but you won't believe what happened.

Lennon-Hair had a thing after my jazz thing and I saw him and I smiled at him but I don't know if he saw and his mom was there and it was so awkward and he was wearing a Beatles shirt and his hair was so SHINY! :speech: :laugh:
