Explosion at Hawaii volcano spews ash as lava flows into sea

A small explosion at the summit of Hawaii's erupting Kilauea Volcano on Sunday sent ash spewing into the air, creating a driving hazard on parts of the Big Island, the U.S. Geological Survey said. Lava fountains from a fissure in the volcano reached as high as 180 feet (55 meters) from Saturday night into Sunday, pushing flows of molten rock into the ocean, it said.
