In Kilauea, the deflation-inflation cycle switched towards inflation on June 24 at about 7 pm local time, both at the top and at Pu'u O'o.
The summit lava lake level is a little higher than the day before. At Pu'u O'o, incandescence is perceived by webcams at the level of the crater and a small basin on the west side of the crater.

The 61 g lava flow is still active, and the lava enters the ocean at Kamokuna, where the lava delta reaches 3.2 acres and extends up to 100 meters from the cliff. Thermal images, taken on June 21st, show a crack cutting the delta in its width, revealing sagging and instability of the latter.
