Pu‘u ‘Ō‘ō lava lake remains active; flows on coastal plain weak

View looking east at the lava lake, 40-m (130-ft) across, that circulates within a shallow pit on the northeast side of the Pu‘u ‘Ō‘ō crater. The heavy fume in the background is the trace of the lava tube that carries lava downslope to the active flows near the coast.
