Yes, there was fountaining last December! I think that noise we heard then was the lava falling back into the caldera, or just the movement overall

The noise from the crater rim sounded like a freight train. It felt big.

When we saw it last December, the guides mentioned it has been a fairly long eruption. More than a year.

Nope. The lesser eyes are objects. The greater eye is a unique creature. Perhaps an object that became sentient or was enchanted, like a gearforged.
