This map shows the coastline at the Kamokuna lava entry on Kīlauea Volcano, with labels denoting areas impacted by the large, progressive lava-delta collapse on December 31, 2016. Nearly all the Kamokuna lava delta collapsed into the sea, along with a large section of the older sea cliff east of the delta.
The red line denotes the current (post-collapse) sea cliff; the land seaward of this line collapsed into the ocean. The blue line refers to the rope line that marks the boundary of the area closed by the National Park Service; a section of this rope line was taken out by the collapse on Saturday. These mapped lines, based on handheld GPS points captured on January 1, 2017, are preliminary and subject to change (HVO geologists are in the field again today). For up-to-date information about access to the new ocean entry viewing area, please consult the Hawaiʻi Volcanoes National Park and Hawaiʻi County websites.
