Lava is still approaching the Hawaiian town of Pāhoa. It already destroyed a house (see below; the red-roofed structure still standing is a garage) and is continuing its march, oozing slowly towards other structures, including the town’s solid waste transfer station (a garbage facility) and power lines. In the picture above, the billowing smoke isn’t coming from the lava, but from the asphalt parking lot that it is burning. Here are some of the more amazing pictures from this week, taken by the United States Geological Survey (USGS).
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.
