HILO, Hawaii - Two lava flows enter the ocean on Sunday. This video - taken by a permitted tour operator Saturday night and shot by seelava.com - is off Highway 137 near MacKenzie State Park.

Sulfur dioxide emissions tripled down wind of that Sunday, with elevated levels in Kamaili, Seaview, and Malama Ki. Access to the area is prohibited, except for permitted tour boats.

One of those lava supplies went underground. A change to the surface flow and a big increase in sulphuric dioxide are some of the latest developments with this eruption.

Hawaii County Civil Defense said on Sunday afternoon that even though lava now reaches the ocean, scientists say other fissures can still open up or reactivate.

The most lava is coming out of Fissure 20. Two of the lava flows reached the ocean around the area of MacKenzie State Park, but after doing so, a crack opened under the eastern flow and sent lava back underground.

There are a number of homes along the coast that are in between the two flows, and may still be standing, but more homes have been destroyed in Malama Ki and Lilipuna areas.

Hawaii County Civil Defense administrator Talmadge Magno says, “It is going be more after the Malama Ki flows, 47 posting. But there will be more counted tomorrow. We’re getting more footage of the drones today and once we get them we can overlay them and it will be more extensive coverage. We will show there were more homes on those properties.”

Volcanic gas emissions have tripled as a result of the voluminous eruptions from sissure 20 so sulphuric dioxide concentrations are likely elevated at higher levels throughout the area downwind of the vents.

Meanwhile at the summit, two explosive eruptions of ash have occurred. Several smaller ash emissions have also taken place. Additional explosions are possible at any time.

Along with sulphuric dioxide and ash concerns, Hawaii County Civil Defense wants everyone to stay safely away from the ocean entries because of the concern from laze, which includes fine particles of glass that people can inhale.

The ocean plumes are dangerous because laze is formed when hot lava hits the ocean sending hydrochloric acid and steam with fine glass particles into the air. Health hazards of laze include lung damage, and eye and skin irritation. Laze plume travels with the wind and can change direction without warning.
