On June 18, 2018, at 6:13 AM, a seismic event occurred at Halema‘uma‘u that produced a relatively ash-poor gas 

Lava enters the ocean entry in the vicinity of Vacationland, producing a vigorous laze plume. Lava flowing into the ocean has built a delta of flows, rock rubble and black sand, which is over 320 acres in size.

Inward slumping of the rim and walls of Halema‘uma‘u continues in response to ongoing subsidence at the summit. Sulfur dioxide emissions from the volcano's summit have dropped to levels that are about half those measured prior to the onset of the current episode of eruptive activity. This gas and very minor amounts of 

Occasionally, minor amounts of lava briefly spill over the lava channel levees. The spill overs are the shiny gray lobes along the channel margins. The lava flow field has been relatively stable with little change to its size and shape over the past few days. View to the east, with the

Lava from fissure 8 travels about 13 km (8 mi) down a well established channel (visible in the center of the image) to an ocean entry at Kapoho. Lava is building a seaward delta that is approximately 320 acres in size. The view is to the southwest with the Kapoho area in the lower right. The white
