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.

“Those who were skillful in Anatomy among the Ancients, concluded from the outward and inward Make of an Human Body, that it was the Work of a Being transcendently Wise and Powerful. As the World grew more enlightened in this Art, their Discoveries gave them fresh Opportunities of admiring the Conduct of Providence in the Formation of an Human Body.”
