Hawaii's Volcano Meets the Sea
Molten lava entering the sea at Kalapana hawaii is a rare occurrence in Hawaii. This photograph has recorded a split second explosion caused by hot molten rock being super cooled in the sea water. The explosion's pyroclastic fragments are the material which washes back to shore to form the famous black sand beaches in the area.
