Happy birthday Pu‘u ‘Ō‘ō! A look back at what happened in 2018
Detailed Description
Glow from an active ocean entry on Kīlauea Volcano's Kamokuna lava delta was visible on the evening of September 27, when the 2017 delta was near its maximum size of 8-10 acres. Since then, the edges of the delta began to crumble into the sea. With no lava entering the ocean since November, ocean waves slowly erode the lava delta, further reducing its size. USGS image.
