The lava cooling operation appears to have been a success. While the water will need to continue - 26 thousand litres per second, enough to fill an Olympic swimming pool every 1 1/2 minutes - work today is expected to increase the height of the L3 berm atop the lava currently being cooled.
The eruption is slowly weakening, though isn't in a rush to end. Primarily of note, the central crater (of three) has significantly declined overnight.
