Kilauea Eruption Update


USGS Hawaiian Volcano Observatory, Status of Kīlauea Volcano, June 12, 2018, Jessica Ball, Volcanologist


Aerial views of the ocean entry on Kīlauea Volcano’s lower East Rift Zone on June 12, 2018, around 6:30 a.m. HST, show multiple small lava streams spilling into the ocean along the southern portion of the lava delta in Kapoho Bay. The interaction of molten lava and ocean water creates “laze,” a corrosive mixture of seawater steam, hydrochloric acid, and fine volcanic glass particles that can irritate the skin, eyes, and lungs. The helicopter overflight traveled from north to south along the coastline. Fissure 8 is visible in the distance near the end of the video.

This thermal map shows the fissure system and lava flows as of 2 pm on Tuesday, June 12. The fountain at Fissure 8 remains active, with the lava flow entering the ocean at Kapoho. Very small, weak lava flows have been active recently near the Fissure 18 area. The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field. The base is a copyrighted color satellite image (used with permission) provided by Digital Globe.

This is a Civil Defense Message for 3 p.m., Tuesday, June 12, 2018.

Hawaiian Volcano Observatory reports fissure 8 continues to produce a large channelized flow that is entering the ocean at Kapoho and producing a large laze plume. Gas emissions from the fissure eruption and at the ocean entry continue to be very high.

Due to volcanic and air quality conditions, the following guidance is given:

  • The Department of Health recommends limiting outside activities and staying indoors if you have breathing issues.
  • An eruption community meeting will be held at 5:00 p.m., tonight, at the Pahoa High Cafeteria.

Due to the current volcanic activity, the following policies are in effect:

  • Leilani Estates west of Pomaikai Street is open only to residents with official credentials.
  • Leilani Estates residents who live east of Pomaikai Street, can contact Civil Defense to schedule an official escort to their homes to retrieve important documents and belongings.
    • Escorted entry is conducted only when conditions are stable and access is subject to change if conditions become unsafe.
    • People with proof of residence can call Civil Defense at 935-0031 during normal business hours.
  • Government Beach Road, between Kahakai Boulevard and Cinder Road is open to Waa Waa and Papaya Farms Road only to residents with official credentials.
  • There is no immediate threat, but residents in these areas should heed warnings from Civil Defense officials and be prepared to evacuate with little notice.

The Pahoa Post Office is open during normal business hours with temporary Sunday hours from 10 a.m. to 2 p.m. for mail and package distribution only for residents in the affected areas. No retail services on Sunday.

For your safety, heed warnings from Civil Defense officials and stay alert.

Due to the lava entry at the ocean, the following policies are in effect:

  • Access to the area is prohibited due to the laze hazard.
  • Stay away from any ocean plume since it can change direction without warning.
  • The U.S. Coast Guard is actively monitoring the ocean entry area and enforcing a 300-meter standoff zone. Only permitted tour boats are allowed in the area.
  • Health hazards of laze include lung, eye and skin irritation.
  • Be aware that the laze plume travels with the wind and can change direction without warning.

Sulfur Dioxide (SO2) and Vog

Volcanic gas emissions remain elevated throughout the area downwind of the vents in lower Puna.

  • Severe conditions may exist such as choking and inability to breathe.
  • Sulfur Dioxide (SO2) gas from fissures are especially dangerous for elderly, children/babies and people with respiratory problems.

County, State, and Federal partners continue to monitor the situation. You will be informed of any conditions that affect your safety.

Monitor vog levels and forecasts: People on Hawaii Island outside the area of volcanic activity are also advised to monitor levels of vog at vog.ivhhn.org

The residents of Puna are going through a very difficult time. We ask for your help and understanding.
