A Giant Pool of Lava Has Been Hiding Under Italy This Whole Time!

Deep beneath the beautiful hills of Tuscany, a giant pool of magma [hot, melted rock] has been discovered hiding underground. Using special sensors to listen to Earth's vibrations, scientists mapped this secret underground reservoir which is big enough to fill over two billion Olympic swimming pools! It is completely safe and won't erupt, but it makes you wonder what other giant secrets are hiding right beneath our feet.
