Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake, Volcano, LANDSAT and Water information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown.
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.
