Wildfire on the island of Hawaiʻi caused by pāhoehoe lava flowing on the coastal plain of Kīlauea. The new lava is moving across the old surface, which is covered with a roughly 1-inch (2.54 cm)-thick layer of moss. The burning moss generates the smoke visible in the image. This kind of fire cannot be easily prevented or suppressed.Photo credit: Mila Zinkova
