There were countless miles of lava tunnels there, left by retreating magma from a time when the Moon was a burning young rock.
Pockets of hot molten rock called magma collect beneath the surface of the Earth.
And then this tremor that everybody's talking about, it lasted for about 50 minutes, meaning that the lava or the magma, which is lava that's below the surface, is actually making its way up towards the surface.
Now scientist first thought magma, which is lava that hasn't yet made it to the ground wasn't moving to the surface.
The resultant body of molten liquid, called magma, will solidify to produce the igneous rock, granite, but if it is still in liquid form as it approaches the surface, lava results.
They form when molten rock called magma up and breaks through a weak area
Instead, it will collect into huge underground reservoirs known as magma chambers.
The mystery lies in the origin of the magma, which is molten rock that forms within the Earth.
Like all volcanos, the eruption started when boiling hot subterranean liquid rock, known as magma, found a weak spot in the Earth's crust and burst through.
As the plates move, rock partially melts and forms magma, which is forced to the surface through a weak spot in the crust.
