Laze alert: Avoid ocean plume and affected area

Two lava flows have entered the ocean off Highway 137 near MacKenzie State Park. Hawaiian Volcano Observatory reported that sulfur dioxide emission rates tripled downwind of the rift today. Areas of Kamaili, Seaview, and Malama Ki have elevated levels. Take action necessary to limit further exposure.

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. Laze is a combination of hydrochloric acid, steam and fine glass particles, and is both toxic and corrosive.

• Stay away from any ocean plume. The plume travels with the wind and can change direction without warning.

• The U.S. Coast Guard is actively monitoring the area. Only permitted tour boats are allowed in the area.

Due to hazardous conditions from lava and fires, the following policies are in effect:

• Highway 137 is closed between Kamaili Road and Pohoiki Road.

• Kamaili Road is closed to all thru traffic. No stopping, this is a high sulfur dioxide area.


• Everyone is asked to stay out of the area.

The residents of lower Puna are going through a very difficult time. Help by avoiding the affected areas.

    Why they are suddenly talking about the “laze”, when there was never any discussion of this during previous lava ocean entries. Why is it now a concern but nobody brought it up before? I certainly don’t recall any injuries from laze happening in the past. And if its so dangerous, why are they sending mixed messages to the public by allowing the lava boat tours to continue?
