September 20, 2024—Kīlauea middle East Rift Zone recent lava flows

Pāhoehoe lava flows paved the floor of Nāpau Crater during the recent eruption on Kīlauea middle East Rift Zone. Pāhoehoe is characterized by smooth, billowy, and ropy surface textures. Recent lava flowed over tephra that previously coated this area of the crater floor. Tephra is a word for cinders and other volcanic products that travel through the air before being deposited on the ground surface. The vegetated areas outside of the crater, above the crater walls, are visible in the background of the photo. USGS photo by M. Patrick.
