An aerial view, looking west, of the two active ocean entries on Kīlauea Volcano’s lower East Rift Zone. The large white plume (foreground) is the eastern ocean entry; the weaker, western plume can be seen in the distance. The white plume, referred to as “laze,” is a mixture of condensed acidic steam, hydrochloric acid gas, and tiny shards of volcanic glass that can irritate lungs, eyes and skin.
