Detailed Description
A wide view of the ocean entry, showing the broad lava delta on the right. Lava deltas (new land formed at the ocean entry) are built on a foundation of rubble, so they can (and do) collapse without warning. Because of this, lava deltas are one of the most hazardous areas on Kīlauea, and people are urged to enjoy the beauty of the ocean entry from a safe distance.
