Looking across floor of Puka Nui on southwest side of Pu`u `O`o, showing new lava pond in crater, new flow descending far (west) crater wall, and fuming 55 cone-pit in background. All black flows were emplaced in past day or two. Floor of Puka Nui is 30-40 m across.
Closer view of crusted lava pond in Puka Nui, looking east. Relatively smooth crust indicates at least one episode of crustal overturning on stagnant lava pond.
View of incandescent Humble vent at base of southwest crater wall of Pu`u `O`o. New lava flows coat floor of crater, and heated rain water rises as steam. View from north rim of crater.
