Good morning everyone, this is the USGS Hawaiian Volcano Observatory update for June 12.


In the Lower East Rift Zone of Kilauea, there is a line of closely spaced vents at fissure 8-not new fissures, just closely spaced vents. They are erupting up to 160 feet, as they have in past days. They are still feeding the fast-moving channelized lava flows to the ocean at Kapoho.


At the ocean entry at Kapoho, we are now seeing what are called littoral explosions, which are steam explosions that occur when lava flows directly into the ocean and does not have any time to cool. These show up in our videos as gray plumes within the overall laze plume, which we are still seeing at the flow front.


We are still seeing weak spattering at fissures 16 and 18 as we have in the past few days, but no other fissures are active at this time. Vog and SO2 emissions are still a concern from the lower east rift zone.


At the summit, at 1:52 am this morning, we had another ash explosions at Halema’uma’u crater. The event and its precursory earthquakes were widely felt in the Volcano area. Following the event, as with previous events, seismicity dropped following the explosion, but we are still seeing slumping from the walls of the Halema’uma’u crater and occasional SO2 and ash emissions are still being seen downwind of the crater.
