Lava
Lava is molten rock that erupts from a volcano and flows on the Earth's surface before cooling and solidifying.
How big is it?
1,373 K
Also 2,012 °F
Temperature · defined reference
A little perspective
Lava is 300 K warmer than Wood fire.
Wood fire: A wood fire is the burning of wood in air, producing heat, light and flames.
Measurements, assumptions & sources +
Lava
A chosen 1,100 °C lava-temperature model; composition and eruption conditions vary.
Defined examples — our methodology
The marked temperature is calibrated. Unmeasured illustration details are representative.
Wood fire
A chosen 800 °C flame-temperature example. Fuel, air supply and position in the flame matter.

Why we use 1,373 K
For comparison, this page uses temperature. This is labelled defined reference: an explicit comparison model rather than a claim that every example has the same value.
