> Last 24 hours at Pu`u `O`o vent: The lava lake level is no longer rising and started falling at 3:21 pm, exposing the levee walls. In addition, the flow from east vent was not sufficient to get all the way to the west end of the lake. The west vent and the western portion of the lake were not active. Yesterday before the level dropped, the lava lake surface was measured to be 31 m below the east crater rim. Overall, it appears that the supply of lava to the lake is dwindling.
