Is the volcano in Iceland slowing down? How can lava travel so far? How does the pressure build up to make it erupt? Can the lava pouring out leave a vacuum inside the planet? Can magma melt again after getting hard? Could you dig a tunnel for the Lava to travel through? Is the Lava hot?

These are some questions we answer in today's Q&A video! If you have more questions for Geologist Ólafur Ingólfsson then please post them down below!
