A new volcanic fissure on the Big Island sent gases and lava exploding into the air, prompting officials to issue calls for more evacuations as residents awaited a possible major eruption at Kilauea volcano’s summit.

Smoke and volcanic gases rise as lava cools in the Leilani Estates neighborhood, in the aftermath of eruptions and lava flows from the Kilauea volcano on Hawaii’s Big Island, on May 11, 2018 in Pahoa, Hawaii. The U.S. Geological Survey said a recent lowering of the lava lake at the volcano’s Halemaumau crater “has raised the potential for explosive eruptions” at the volcano. Vog, a haze or smog containing gases, smoke and dust from volcanic eruptions, may eventually spread from the eruptions to other islands in Hawaii. (Photo by Mario Tama/Getty Images)
