Detailed Description
Lava entering the sea on the western side of flow "61g" is building a platform of new land known as a lava delta, which appears deceptively stable. However, the veneer of lava on the delta surface hides a foundation of loose rubble. As a result, lava deltas are extremely unstable, and they can—and do—collapse without warning. The white plume produced when lava enters the sea is a corrosive mixture of superheated steam, hydrochloric acid, and tiny particles of volcanic glass, and should be avoided.
