The active lava lake in Pu‘u ‘Ō‘ō and its levee

View looking east into Pu‘u ‘Ō‘ō, its crater partly filled by lava flows accumulating on the crater floor. The active lava lake in the crater is 205 m (673 ft) long and varies in width from 80-115 m (262-377 ft). The West Gap pit is in the central foreground, and the Puka Nui and MLK pits are to the right (the MLK pit is in back). The crater has filled in vertically about 100 m (328 ft) since the crater collapsed on March 5, 2011, at the start of the uprift Kamoamoa eruption. It still has about 12 m (39 ft) to go to reach the level of the crater floor prior to the collapse.
