A close-up of one of several streams of lava entering the ocean at the front of the Kamokuna lava delta on KÄ«lauea’s south flank. The billowy white plume formed by the interaction of hot lava and seawater may look harmless, but it is a mixture of superheated steam, hydrochloric acid, and tiny shards of volcanic glass—all of which should be avoided.
