In Kamokuna, a partial collapse of the lava delta formed by the 61 g lava flow of the Pu'u O'o gave rise to an impressive breakout on 25 June around noon. An observer from Lava Ocean Tours reports the rupture of the lava tunnel, coinciding with the lava flow on the delta ... including an a'a flow, which was rarely seen at the entrance of the lava in ocean during episode 61g.
This collapse was expected, as an overflight and thermal images of 21 June showed a crack in the width of the delta (link)

The Bogoslof is redirected in red aviation alert, following an eruption begun this 27th June at 11:17 UTC. It has been indicated by the seismometers and the volcanic light monitoring system. The eruption took about 14 minutes. Substantial ash emissions have occurred, with a cloud of ashes reaching over 9,000 meters.
This eruption occurs less than 12 hours after the previous one, justifying the maintenance of the red code.
