Pu‘u ‘Ō‘ō — Lava Lake

The lava lake on the northeastern edge of the Pu‘u ‘Ō‘ō crater floor is about 30 m (100 ft) across. It's level rises and falls with changes in pressure in the magma storage body beneath Pu‘u ‘Ō‘ō. Today, the lava lake was at a relatively low level, compared to its condition over the last few months.
