Whenever I talk about plate tectonic settings, there's three different types I can really talk about.
Number one is whenever you've got plates pulling apart.
That's what's happened here.
We also have plates sliding past each other.
That really only leads to things like earthquakes.
And then the other one is whenever we've got plates going towards each other.
So whenever you've got them going towards each other, what will generally happen is you'll get one plate going beneath, or they'll simply be pushed together and they'll form mountains.
And they tend to produce very different types of volcanoes.
They are the volcanoes in people's heads.
They think of the cone volcanoes, the classic volcano.
Here it's a very different plate tectonic setting, so we get very different types of rock formations.
So if I'm going to be honest with you, a volcano here would have been really unimpressive.
It would have been a fissure eruption.
So it essentially would have been a crack in the earth up through which lava bubbled and it would have flowed out across the surface.
So we're talking about volcanic activities as opposed to classic volcanoes.
Pretty much.
So Indonesia is not exactly the same.
They do have the same type of rocks in that they are basalt, but basalt has got many different types of variations depending on the slight differences in composition.
And the difference between here and Indonesia is also the volcanic setting.
So here we've got volcanoes that formed from seafloor spreading, from tectonic plates moving apart.
