What is the meaning of Puu Oo?
From Wikipedia, the free encyclopedia Puʻu ʻŌʻō (often written Puu Oo, pronounced [ˈpuʔu ˈʔoːʔoː], poo-oo-OH-oh) is a volcanic cone in the eastern rift zone of the Kīlauea volcano of the Hawaiian Islands.

Is Puu Oo still erupting?
Based on historical data, it's unlikely that lava will erupt again from Pu'u 'Ō'ō, but the East Rift Zone still has magma underneath, and it will erupt again through another vent. It may take several years for enough magma to accumulate again, but Kīlauea and the East Rift Zone remain very active.
What caused the formation of Kilauea?
Like all Hawaiian volcanoes, Kīlauea was created as the Pacific tectonic plate moved over the Hawaiian hotspot in the Earth's underlying mantle. The Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has created the 6,000 km (3,700 mi)-long Hawaiian–Emperor seamount chain.
How is PU formed?
The formation of Pu'u Ohau began when magma from the central magma chamber found its way through a conduit system to the area where Pu'u Ohau now lies (fig. 2a). A fissure opened up approximately 2.2 km upslope from the crater of Pu'u Ohau, and lava began to pour out.
