On May 24, 2016, a new vent opened on the east flank of Pu‘u ‘Ō‘ō that cut the supply of lava to the June 27th flow, which became inactive by June 8, 2016. Lava from the new vent, informally named the "61g" flow by the Hawaiian Volcano Observatory, flowed south and began entering the ocean at Kamokuna on July 26, 2016. Lava from the 61g flow covered part of the regraded (but never reopened) new section of the Chain of Craters Road. The road is kept flat for use by authorities, but is no longer a public thoroughfare.
