Risky actions at Kīlauea's ocean entry are cause for concern

Do not be misguided by the risky actions of this person (upper right), who is standing on an active lava delta that could collapse without warning, amidst a plume of superheated steam, hydrochloric acid, and tiny particles of volcanic glass. To avoid these ocean entry hazards, HVO advises staying at least 400 m (one-quarter mile) from where lava enters the sea. USGS photo, March 2013.
