This Quicktime movie shows the refilling of Pu‘u ‘Ō‘ō over the past two months, taken from a thermal
camera on the south rim of the crater. Lava
drained from Pu‘u ‘Ō‘ō on March 5 during the Kamoamoa fissure
eruption, and remained absent for several weeks. This thermal camera began recording on March 18, and shows the abrupt return of lava
to the crater floor on March 26. Lava refilling has been very unsteady since then, occurring in fits and starts, and has culminated in the development of a perched lava lake
over the past several weeks. This perched lava lake has steep walls about 8-10 m (26-33 ft) above the surrounding crater floor. The temperature scale is in degrees Celsius.
