Due to a forecast of decreasing tradewinds, residents are advised to monitor their sensitivity to increased levels of sulfur dioxide (SO2) in the latter part of the week.

The Hawai‘i Volcanoes National Park will close indefinitely starting Friday due to the possibility of an explosive steam event and ash fall at the summit of Kīlauea Volcano.  Rangers say the closure is being implemented due to a combination of factors including a receding lava lake, an ensuing ash fall event on Wednesday, plus southerly wind patterns forecast for Friday.

The Hawaiian Volcano Observatory confirmed a 15th fissure.  The outbreak started Wednesday in the Lanipuna Subdivision and has since paused, but hazardous fumes continue to be released.

Since its onset last week, the East Rift Zone eruption has resulted in 15 fissures, nearly 117 acres covered by lava, and 36 structures destroyed.  As of midnight, there were over 200 residents at the Pāhoa shelter and 24 residents at the Keaʻau shelter.

  • Conditions permitting, Leilani Estates residents will be allowed to check on their property from 7 AM to 6 PM each day until further notice.  Be prepared to evacuate at a moment’s notice.

    Ash column rises from the Overlook crater at the summit of Kīlauea Volcano. HVO’s interpretation is that the explosion was triggered by a rockfall from the steep walls of Overlook crater. The photograph was taken at 8:29 a.m. HST on Wednesday, May 9, 2018, from the Jaggar Museum overlook. The explosion was short-lived. Geologists examining the ash deposits on the rim of Halema‘uma‘u crater found fresh lava fragments hurled from the lava lake. This explosion was not caused by the interaction of the lava lake with the water table. When the ash cleared from the crater about an hour after the explosion, geologists were able to observe the lava lake surface, which is still above the water table. PC: US Geological Survey 5.9.18

    At 1 p.m. HST on Wednesday, May 9, 2018. A new fissure extended across Pohoiki Road between the intersections of Leilani Avenue and Hinalo Street.
