Formation
Lava lakes can form in three ways:
- From one or more vents in a crater that erupts enough lava to partially fill the crater
- When lava pours into a crater or broad depression and partially fills the crater
- Atop a new vent that erupts lava continuously for a period of several weeks or more and slowly builds a crater progressively higher than the surrounding ground.
