Who erupted the lava?

Description from original post (created 2014-04-27 00:14):

Volcanoes erupt due to underground force pushing up the magma causing lava to splatter everywhere.

Or do they?

Long ago, probably when the dinosaurs roamed the earth, volcanoes where everywhere, and a young goddess named Volcania was born, but in a strange way. She erupted from a volcano. She was rumored to have the power to cause magma to erupt from far into the depths of the world. So she was hidden undergrond to prevent lava leakage. She grew up in the Earth's core. she managed to find resources such as dirt and coal, for strangely creating clothing, because she controls the Earth core and resources. She rests for centuries. When awakened, which is pretty hard because only a severe earthquake can wake her up, she erupts magma from certain volcanoes across the world, depending on where she rested. When you see a large amount of lava, you know she is close.
