Print article HONOLULU — Lava was rising more than 3 feet per hour in the deep crater of a Hawaii volcano that began erupting over the weekend after a two-year break, scientists said Tuesday. Kilauea volcano within Hawaii Volcanoes National Park on the Big Island was gushing molten rock from at least two vents inside its summit crater, the U.S. Geological Survey said. A lava lake has formed, rising about 440 feet from the bottom of the crater. Since the eruption began Sunday night, Kilauea has spewed some 2 billion gallons of lava, enough to cover 33 acres. The lava has been contained inside the deep crater.
