“A message from COUNTY OF HAWAII

This is a Civil Defense message for Friday, July 20 at 6:00 in the morning.


The Hawaiian Volcano Observatory reports that eruption activity continues from Fissure 8 into the lava channel flowing to the ocean entry at Ahalanui producing a large laze plume. As of yesterday’s overflight report, the southern margin of the flow is approximately 0.25 miles from Isaac Hale / Pohoiki Boat Ramp.

On roadway updates for the Volcano area, State Highways reports that a speed limit of 25 miles per hour is in effect on Highway 11 between the 28 and 30 Mile Markers due to cracks in the road.  Motorists are advised to stay on the pavement and be on the alert for cracks in the road and to exercise caution.


The following policies remain in effect:

  • Do not access the active flow field due to extreme hazard. Be aware that channel overflows and 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, located at the Keaau High School Gym, is open daily from 8 AM to 6 PM weekdays and 8 AM to 4 PM on Saturdays. If you need a ride, buses run between the two shelters and the Disaster Recovery Center.
  • Visit www.DisasterAssistance.gov to register online and for a list of information to bring to the Disaster Recovery Center.
  • Access placards are available at the Civil Defense office located at 920 Ululani Street in Hilo.

We are on watch 24-hours a day for your safety.
