Detailed Description
The lava pond in the northeast portion of Pu‘u ‘Ō‘ō crater remains active, and has built up a slightly elevated rim following several overflows over the past week. Today the pond was gently gas pistoning - a process that involves the cyclic rise and fall of the lava level due to gas buildup and release.
