HONOLULU, Hawaii (AP) \u2014 The Kilauea volcano on Hawaii's Big Island has erupted, the U.S. Geological Survey said.\r\n\r\nThe eruption began late Sunday within the within Halema'uma'u crater. The volcano is located within Hawaii Volcanoes National Park.\r\n\r\nA magnitude 4.4 earthquake hit about an hour after the volcano began erupting.\r\n\r\nBy 1 a.m., USGS officials told Hawaii News Now that there were reported lava fountains shooting about 165 feet (50 meters) into the sky and feeding a growing lava lake within the crater that used to hold water.\r\n\r\nDavid Phillips, a Hawaiian Volcano Observatory spokesman, said the agency was monitoring the situation.\r\n\r\n"We will send out further notifications on Kilauea and other Hawaiian volcanoes as we observe changes," he said.\r\n\r\nThe USGS said it received more than 500 reports of people who felt the earthquake but significant damage to buildings or structures was not expected.\r\n\r\nAn advisory was issued by the National Weather Service in Honolulu, warning of fallen ash from the volcano. Excessive exposure to ash is an eye and respiratory irritant, it said. The agency later said the eruption was easing and a "low-level steam cloud" was lingering in the area.\r\n\r\nKilauea erupted in 2018, destroying more than 700 homes and spewing enough lava to fill 320,000 Olympic-sized swimming pools. An area more than half the size of Manhattan was buried in up to 80 feet (24 meters) of now-hardened lava. The lava flowed over the course of four months.
