Eruption begins on Kīlauea Volcano's lower East Rift Zone

Eruption begins on Kīlauea Volcano's lower East Rift Zone...
An eruption has commenced in the Leilani Estates subdivision in the lower East Rift Zone of Kīlauea Volcano. White, hot vapor and blue fume emanated from an area of cracking in the eastern part of the subdivision. Spatter began erupting shortly before 5:00 p.m. HST. Lava was confirmed at the surface in the eastern end of the subdivision, in the areas of Mohala and Leilani Streets. According to a Hawai‘i County Civil Defense update at 5:40 p.m., all residents in Leilani Estates and Lanipuna Gardens Subdivsions are required to evacuate.

 

The opening phases of fissure eruptions are dynamic. Additional vents and new lava outbreaks may occur and at this time it is not possible to say where new vents may occur.
This video shows the small fissure that opened in the Leilani Estates subdivision today around 5:00 p.m. The fissure was active until about 6:30 p.m.
Areas downslope of the erupting vent are at risk of lava inundation. At this time, the general area of the Leilani Estates subdivision appears at greatest risk. Hawai‘i County Civil Defense is on scene and coordinating needed response including evacuation of a portion of the Leilani subdivision.
Residents of the lower Puna District should remain alert, review individual, family, and business emergency plans, and watch for further information about the status of the volcano. Hawai‘i County Civil Defense messages may be found at http://www.hawaiicounty.gov/active-alerts/.
After a long period of rain and low clouds, improved weather and a high cloud deck today allowed good airborne observations of the collapse crater in Pu‘u ‘Ō‘ō. This photo looks towards the east, and shows the deep collapse crater formed on Monday, April 30, when magma beneath Pu‘u ‘Ō‘ō drained. For scale, the crater is about 250 meters (820 feet) wide.
This wide shot looks northeast, and shows the fissure that formed on the west flank of Pu‘u ‘Ō‘ō cone. The fissure extends roughly 1.5 km west of Pu‘u ‘Ō‘ō Crater, and nearly reaches the bottom of the photograph.
Another wide view, from the east, showing the dust-rich plume and coating of reddish ash to the south of Pu‘u ‘Ō‘ō.
A view of Pu‘u ‘Ō‘ō from the east, shortly after a small collapse. The coating of red ash on the south side of the cone (left side of photo) is evident.
At 10:31am, a magnitude 5.0 earthquake shook the ground around Pu‘u ‘Ō‘ō while HVO geologists were working on the cone. Moments later, a collapse occurred in the crater, creating a robust ash plume.
HVO geologists confirmed that the Episode 61g flow is now inactive. Thermal images showed no active breakouts on the flow field. This photo shows the area where breakouts were focused prior to magma draining from Pu‘u ‘Ō‘ō earlier in the week.
At 10:30 HST, ground shaking from a preliminary magnitude-5.0 earthquake south of Pu‘u ‘Ō‘ō caused rockfalls and possibly additional collapse into the Pu‘u ‘Ō‘ō crater on Kīlauea Volcano's East Rift Zone. A short-lived plume of ash produced by this event lofted skyward and dissipated as it drifted southwest from Pu‘u ‘Ō‘ō. Downwind areas may have experienced a dusting of ash from this plume. At this time, the 10:30 earthquake has caused no other changes at Kīlauea Volcano. HVO will continue to closely watch monitoring data for any changes. This image was captured from an HVO overflight carrying HVO scientists to the East Rift Zone for field work today. USGS photo by Kevan Kamibayashi.
