After concentrating chakra around their body, chakra races from the users body outwards, traveling far from the user. The user then concentrates chakra in their body before releasing it directly under their feet. Seconds later, super heated magma burst out of the ground, racing outwards at high speed, covering everything in its path for 40+ meters. Because of the sheer scale of this jutsu, it consumes a lot of the users chakra, making this a jutsu not normally used more than once per battle.
