It might seem like the lava in some of these pictures has fully solidified, but in some places underneath that black solid-looking surface is still a good amount of molten lava, as you can see in the thermal image below of the leading edge of the lava flow. The purple and red colors are cooler temperatures, while the yellow and white indicate very high temperatures, where the flow is more active. Of course, there are a few places where you can clearly see the bright orange-red glow that you typically think of when you imagine a lava flow. If even these pictures aren’t enough to satiate your desire to see lava, check out videos of the lava flow from The Guardian or NBC.
