Vintage volcanism, used as B-roll in an early 1960s NASA film. Here are some hot lava fun facts: When first erupted from a volcanic vent, lava is a liquid at temperatures from 700 to 1,200 °C (1,292 to 2,192 °F). Up to 100,000 times as viscous as water, lava can flow great distances before cooling and solidifying.
