Kīlauea's Kamokuna ocean entry reaches its 1-year anniv.

Kīlauea Volcano's Kamokuna ocean entry photographed on May 23, 2017 (left) and July 13, 2017 (right) show how lava flowing from the tube has both widened and thickened the delta. Near the sea cliff, the delta appears to have doubled in thickness over the past seven weeks, creating a distinctly sloped surface from the base of the cliff to the sea. As of mid-July, the Kamokuna lava delta was estimated to be about 1150 feet (350 m) wide and about 6 acres in area. Large cracks on the delta indicate its instability and potential for collapse.
