Tiberium vein detonation

Yet another in a long line of Nod military applications of Tiberium, the Vein Detonation is an extremely lethal support power. Although exact damage is unknown, it is believed that the vein detonation is about as powerful as Nod's standard nuclear weaponry

As Tiberium has spread throughout the Earth, underground veins of the mineral also are found worldwide. Using similar technology to the catalyst missile, the vein detonation causes the subterranean deposits under a given locale to explode. However, the vein explosion is significantly more violent and destructive than the catalyst missile, and it causes massive damage to any target above the vein.
