Delta Erosion

 

Delta Erosion...

The Kamokuna delta on Kīlauea's south flank continues to erode from wave action against the rock. A small sea arch present only 2 weeks ago has now collapsed, with only a small column sticking up above the waves (far left of the image). An unstable sea cave is being eroded into the delta (dark area in the middle of the image), and will continue to change with wave action. The tumulus that formed at the end of the delta's activity in November is still visible as a double-peaked mound.
