Scientists have discovered a vast reservoir of magma bubbling beneath the Tuscan soil that may not yet have erupted. With no obvious volcano to mark the spot, the immensity of the system and its extreme heat had gone unmeasured until now. The Tuscany region is home to only sparse volcanic activity, and yet, 8 to 15 kilometers (5-9 miles) deep, scientists estimate that more than 5,000 km 3 of magma and partial melt roils and churns. That's a volume of supercritical fluids roughly on par with the
