Hawaii is bracing itself for a possibly explosive volcanic eruption.
Since Saturday, two lava fissures have opened up on Hawaii's Big Island in the vicinity of a geothermal energy plant.
Just hours after the first fissure opened up on Saturday morning, red and black lava had piled up about 40 feet high and more than 150 feet in length, while magma chunks sprayed up to 100 feet in the air, Reuters reported.
Scientists originally said two more had opened since then, but they later downgraded that to one, noting that one of the cracks that had opened up did not emit lava and was therefore not an active fissure.
Hawaii's Kilauea volcano has been continuously erupting for years, but an uptick in eruptions and earthquakes in recent days have ramped up the danger for residents of Hawaii's Big Island.
Thousands of people have now been forced to evacuate, and the eruption has already destroyed dozens of structures. Geologists are warning that the volcano's summit crater could soon begin spewing huge boulders and ash.
Here's what it looks like on Hawaii's Big Island:
The first new fissure opened on Saturday morning. The US Geological Survey said lava was splattering from the crack.
The Hawaiian Volcano Observatory said the fissure erupted east of the Puna Geothermal Venture plant and northeast of the Lanipuna Subdivision.
Plant workers this week removed the 50,000 gallons of pentane stored at the site as a precaution.
Then, another crack opened, bringing the total number of fissures to 17.
The Hawaii County Civil Defense issued an alert Sunday morning that steam and lava spatter were coming from the new fissure.
They are ordering residents on that road to evacuate. Community centers are open to shelter people and pets.
Geologists are warning that the Kilauea volcano could shoot out large boulders and ash out of its summit crater.
President Donald Trump on Friday declared a major disaster on the Big Island.
His declaration will make federal financial assistance available to state and local governments as they repair roads, public parks, schools, and water pipes damaged by the eruption.
Near a fissure where lava comes up from the ground, the toxic gasses burn your nose, throat and lungs. The air smells like rotten eggs or a recently extinguished match.
Although you can't really see them, it's the gasses that could hurt, or even kill you. That could be why some residents want to stick it out and not evacuate, feeling the danger is exaggerated.
As the lava flows cool, they crackle and smolder, with smoke rising in gray or black plumes. When it hardens, and the black lava breaks and falls to the ground, it sounds like glass breaking.
The heat near the lava becomes unbearable the closer you get. Even the cooler flows that are only creeping along slowly generate enough heat to turn you back. You can feel the warmth from the ground in the soles of your shoes.
Associated Press journalists Caleb Jones, Jae Hong, Haven Daley and Sophia Yan have spent parts of the past week covering the lava in Hawaii, shooting video and photos and talking to residents about the volcano that's destroyed 26 homes and 10 other structures and forced thousands to evacuate ahead of a possible explosive eruption.
