), For recent maps of activity, see: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html. This morning, a steady, vigorous plume of steam and occasionally minor amounts of ash is rising from the Overlook vent and drifting downwind to the southwest. The central feature of Hawaii Volcanoes National Park , Kilauea (“Much Spreading” in Hawaiian), is an elongated dome built of lava eruptions from a central crater and from lines of craters extending along east and southwest rifts, or fissures. Resources on volcanic ash hazards and preparedness information: https://volcanoes.usgs.gov/volcanic_ash/ OR http://www.ivhhn.org/ash-protection, National Weather Service ashfall information and advisories: https://forecast.weather.gov/. Events at the summit of Kīlauea over the past few weeks have dramatically reshaped Halema‘uma‘u, shown here in this aerial view, which looks west across the crater. Overnight, lava fountaining at Fissure 8 fluctuated, reaching heights of 230 feet. Trade wind conditions are expected to bring vog to the south and west sides of the Island of Hawaii. Earthquake activity continues, but earthquake locations have not moved farther downrift in the past few days and the number of located earthquakes remains low. Additional ground cracking and outbreaks of lava are possible in the area. Lava has added about 380 acres of new land into the sea. Ash continued to erupt intermittently from the vent within Halemaʻumaʻu crater at Kīlauea's summit. That flow was moving atop the Fissure 8 flow that was active the previous night, passing on to open ground and crossing Pohoiki road at about 5am HST. Continuing ground deformation and located earthquakes were mostly in the area around and northeast of Fissure 15 at Pohoiki Road indicating that the intrusion is migrating further to the northeast. Volcanic gas emissions at the summit remain high. Fissures 16 and 18 continue to ooze lava. Trade winds took the ash clouds primarily to the southwest. Volcanic gas emissions at the summit remain high. KILAUEA SUMMITDeflationary tilt at the summit of the volcano continues and seismicity remains elevated. Inward slumping of the rim and walls of Halemaʻumaʻu continues in response to ongoing subsidence at the summit. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Earthquake activity is elevated at the summit, with many small events occurring overnight. Kīlauea Volcano SummitAfter this morning's small explosion at Kīlauea's summit, seismicity levels immediately dropped but gradually increased over the course of the day climbing to about 30 events per hour by nightfall. Fissure 7 activity increased overnight, with lava fountains reaching 150-200 feet high and producing a large spatter rampart over 100 feet tall. This activity is feeding a lava channel flowing east to the ocean entry in the Kapoho Bay area. Spatter built up the cone to the east and into the channel. It is unknown whether the flows will continue to advance, or stop, and new lava flows are likely given the rate of activity seen at the rift zone. The Crater Rim Drive road (middle) now ends at Halema‘uma‘u instead of the parking lot. The flows are no longer active. By June 6, lava had completely filled Kapoho Bay and built a delta that now extends over a mile from shore. The National Weather Service observed an ash column rising to 12,000 ft at around 11 am this morning but visibility was very poor on the ground and ground observers could confirm the event. We expect that earthquake rates will increase in the coming hours and culminate in another small explosion, perhaps within the next day, following the pattern of the past few weeks. Depending on wind conditions, dustings of ash may occur in the Kīlauea summit area and downwind. Seismicity and deformation are consistent with continued accumulation of magma within the rift zone. A late afternoon overflight showed that the ocean entry is creating a vigorous steam plume that is being blown inland to the southwest. The cloud did not contain much ash and dispersed quickly. As of the morning of June 5, the fissure 8 lava flow front had completely filled Kapoho Bay. Minor overflows of the channel levees have occurred at several places along the channel, but have been short-lived and do not pose an immediate threat to areas not previously covered by lava. Major changes over time include: (1) a darkening of the terrain south of Halema‘uma‘u, which reflects accumulation of ash; (2) enlargement of the summit eruptive vent on the floor of Halema‘uma‘u. For the next few days, easterly wind conditions may bring vog not only to the south and west sides of the Island of Hawaii, but also upslope to the island's interior. This 3D model of the crater was created from thermal images collected during a helicopter overflight on May 8. However, as the eruption progresses, other areas of the lower East Rift Zone may also be at risk.High levels of volcanic gas including sulphur dioxide are being emitted from the fissure vents. Today, lava fountains from Fissure 8 reached heights between 100 and 130 ft with bursts up to 180 ft while the cinder and spatter cone that is building around the fissure is now about 170 ft at its highest point. The limited activity at fissures 16 and 18 of the past several days (spattering and small flows) continues this afternoon. In several instances, such collapses have also incorporated parts of the older sea cliff. Kīlauea Volcano SummitAsh continued to erupt intermittently from the vent within Halemaʻumaʻu crater, at Kīlauea's summit. Volcanic gas emissions remain very high from Fissure 8 eruptions. The location of activity today was focused on the southwest portion of the area. Lava from Fissure 8 continues to flow through the well-established channel to the ocean at Kapoho, with rare, small overflows of the channel levees. The size and shape of the flow field is virtually unchanged upslope, but an additional 120 acres have been added to the western margin of the flow in the coastal area since last Friday, June 15. The USGS–Hawaiian Volcano Observatory and Hawai‘i Volcanoes National Park's Jaggar Museum are visible on the caldera rim (center right); Kīlauea Military Camp can be seen in the lower right. Lava eruption continued at Fissure 8 with vigorous fountains reaching heights of about 220 feet. Helicopter overflight of Kīlauea Volcano's lower East Rift Zone shows the lava channelemerging from Fissure 22 (not visible, but to the center, far right of the image). Deflationary tilt at the summit of the volcano continues and the lava lake level continues to drop. The direction of motion is consistent with renewed movement of magma in the downrift direction (to the northeast). Deflationary tilt at the summit of the volcano continues and seismicity remains elevated. Video 1 shows the flow on May 25, around 2:15 a.m. HST. Areas uprift and downrift of the current fissure zone are the most likely to see further outbreaks. Fountaining is occurring at Fissure 17, and Fissures 16-20 have merged into a continuous line of spatter and fountaining. The video is used to assess hazards at the summit and the information is shared with the National Park Service and emergency managers. Residents should remain informed and heed Hawaii County Civil Defense closures, warnings, and messages (http://www.hawaiicounty.gov/active-alerts). Limited UAS flights into this hazardous area are conducted with permission and coordination with Hawai‘i Volcanoes National Park. Please credit "U.S. Geological Survey" for any imagery used. This morning, the summit plume is whitish, reflecting mostly steam mixed with some ash. Kīlauea Volcano SummitEarthquake activity dropped after this morning's small explosion and is now slowly rising following the pattern of previous events of this type. Over time, expansion of the summit eruptive vent within Halema‘uma‘u crater and the widening of Halema‘uma‘u itself are clear. Morning overflight of Kīlauea Volcano's lower East Rift Zone by the Civil Air Patrol provides context for the location of the fissure 8 fountain and lava channel within the lower Puna District. No other fissure vents showed significant activity at this time. Fissure 8, the channel, and the ocean entry are relatively stable with only a small amount of expansion at the southern boundary of the flow near the coast and south of Vacationland. Overall seismicity in the area has not changed significantly overnight and remains elevated. This gas and minor amounts of ash are being transported downwind, with small bursts of ash and gas accompanying intermittent explosive activity. The National Weather Service Nexrad radar tracked the cloud for 15-20 minutes.
