I feel like she could've probably sealed that volcano with her power lol

“Nothing grows from the ground she’s stepped on” is perfect lol

That was my first reaction, too, that she could just pump a bunch of water at the magma to cool it off. Then I remembered that steam exists. A lot of the explosive power of a volcano explosion can come from underground water being heated past the boiling point. Steam expands to 1,600 times as much space as liquid water, and magma is certainly hot enough to get it there quick enough to blow the top off of the volcano.
