The Kilauea Volcano in Hawaii has erupted again this week in a national park, prompting gas warnings from officials. Kilauea erupted briefly Sunday night in a section of Hawaii Volcanoes National Park that remains off-limits to the public.

“Current activity is taking place in a remote area of Kilauea’s middle East Rift Zone, within Hawaii Volcanoes National Park. No changes have been detected in the lower East Rift Zone, or Southwest Rift Zone,” HVO scientists said.
