Updated Kamokuna ocean entry map

Updated Kamokuna ocean entry map...

Detailed Description

This map updates the preliminary ocean entry map below, based on mapping conducted on January 3, 2017. The map of the coastline at the lava flow ocean entry at Kamokuna shows the areas of the lava delta and adjacent coastline that collapsed into the ocean on December 31, 2016. The collapsed areas are shown with an 'x' pattern and a blue background and are now part of the ocean. The shape of the eastern Kamokuna lava delta was revised based on satellite imagery acquired on December 25, 2016. The remaining sections of the lava delta, including the inactive western Kamokuna delta, are shown as a stippled pattern with a pink background. The active lava tube is shown with a yellow line and is dashed where its location is uncertain. The current ocean entry point, where lava cascades into the water, is located where the lava tube intersects the sea cliff. The NPS ropeline is shown as a dashed black line. The western extent of the ropeline was not mapped and is therefore not show; the eastern extent of the ropeline was moved on January 3, and has been approximated on this map between the emergency road and the coast. The dotted black line inland from the coast marks the location of the sea cliff before the Pu‘u ‘Ō‘ō eruption began in 1983. The background is a Digital Globe satellite image acquired January 9, 2016; the episode 61g lava flow is the partly transparent area that overlies the background image.
