Lava fountain erupts from the growing Pu‘u ‘Ō‘ō vent during eruptiv...

The Pu‘u ‘Ō‘ō vent began forming a distinct central-cone during episode 3 in March-April 1983. By the end of episode 4 in mid June, the main part of Pu‘u ‘Ō‘ō was a steep-sided spatter cone about 20-30 m high and 100 m wide. The cone was breached on the south side, through which lava spilled during subsequent episodes and fed flows that extended into the western part of Royal Gardens subdivision. At the end of episode 8, the cone was nearly 60 m (200 ft) above the pre-eruption ground surface.
