Supervolcano Eruption Technique

By pouring a huge amount of chakra into the earth, the user creates a destructive to appear out of the earth and cause a violent eruption. The eruption causes lava and debris to come out of the volcano and destroy everything in it's path. Despite it's power, this technique is classed as Kinjutsu due to the fact that this requires a lot of chakra to use, killing the user in the process. Even if the user manages to survive, they can still be killed in the crossfire due to the nature of this technique (behaving like an actual volcanic eruption). This technique also vastly changes and damages the surrounding landscape.
