This thermal map shows the fissure system and lava flows as of 12:30 pm on Friday, August 3. The fountain at Fissure 8 remains active, with the lava flow entering the ocean. The dominant ocean entry points were on the section of coastline near Ahalanui. 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.

Kilauea Eruption Update

This is a Civil Defense Message for 6 a.m., Saturday, August 4, 2018.

The Hawaiian Volcano Observatory reports that earthquakes continue at Kilauea summit. Fissure 8 continues to erupt lava into the perched channel, sending flows to the ocean at Ahalanui and creating a large laze plume. The margin of the flow at the ocean entry has not advanced and remains approximately 500 feet from the Pohoiki boat ramp.

Motorists on Highway 11 between the 28 and 32 mile marker are advised to stay on the pavement, be alert for changing roadway conditions, and drive with caution. Motorcyclists and bicyclists should proceed with extreme caution.

The following guidelines remain in effect:

  • Check all utility connections of water, gas, and electricity for potential damage from earthquake activity.
  • Do not access the active flow field due to extreme hazard. Be aware that channel overflows and other breakouts are possible on the active flow field.
  • The ocean entry continues to produce a laze plume. Take precautions and stay out of the plume to avoid exposure to hydrochloric acid and glass particles, which can irritate the skin, eyes, and lungs.

Disaster assistance is available island-wide to individuals and businesses in Hawaii County that have been affected by the Kilauea eruption.

  • The Disaster Recovery Center has moved and is now at the Pahoa Community Center, located at 15-3016 Kauhale St., Pahoa. Hours of operation are 8 a.m. to 6 p.m. weekdays and 8 a.m. to 4 p.m. on Saturdays.
  • Access placards are available at the Civil Defense office located at 920 Ululani Street in Hilo.

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. Mail delivery has resumed for areas where roadways have reopened. No retail services on Sunday.

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

Ocean entry laze

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.

Illustration of Kīlauea Volcano from the summit caldera to the lower East Rift Zone (LERZ). Blue arrows = contraction across the upper and middle rift zone, black arrows = expansion in LERZ. Blue arrows indicate contraction across the upper and middle rift zone as magma withdrew from this area and moved down the rift zone beginning on April 30, 2018. Black arrows indicate expansion across the rift zone as magma intruded into the LERZ; the widening on about May 18, 2018. Also, beginning in early May, magma began moving from the summit reservoir into the East Rift Zone. Data sources used in this modeling are from the U.S. Geological Survey/ University of Hawaii, NASA, Jet Propulsion Laboratory, Japan Aerospace Exploration Agency/ and the European Space Agency.
