Well, not quite the centre. Some magma chambers – underground reservoirs of molten rock – lie just a few kilometres below Earth’s surface, putting them within reach of modern drills. They occasionally leak magma to the surface, where it spews out as lava. That is exactly what was starting to happen, to spectacular and devastating effect, around the town of Grindavík in southern Iceland, as this story went to press. The trouble is, we don’t normally know where magma chambers lie. “No geophysical technique has been shown to satisfactorily locate magma reservoirs,” says John Eichelberger at the University of Alaska Fairbanks.
So then how the frick do they know what the planets cross-section looks like?

I was considering going to Iceland for a week over the Holidays. I did a little research and was surprised to see the average temperature in December was 36F. I expected much colder (single digits). Apparently the "Warm" ground causes a sort of microclimate making it warmer in the winter than it rightly should be.

Yep, good ole Leif pulled a fast one on everybody.

Iceland has a geologic rift plate under it so as the tectonic plates pull apart magma wells up to fill the gap. That puts a lot of magma either very near the surface or literally on it.
Yeah, there's that and a mantle plume (hot spot) under it also. Why else would the mid Atlantic ridge be above sea level instead of being under thousands of feet of water?

It will be Lake Peigneur in reverse with the added bonus of molten lava.
