Kilauea, one of the most active volcanoes in the world, is erupting again, and this time in an area that has been inactive for half a century. Alert levels have been raised across Hawaii Volcanoes National Park as there are concerns the eruption could flare up again despite only lasting six hours on Monday. 

The US Geological Survey's Hawaiian Volcano Observatory said the eruption was about 1 mile south of the Kilauea caldera inside Hawaii Volcanoes National Park. The last time this area experienced an eruption was in December 1974.

"Glow is visible in webcam imagery, indicating that lava is currently erupting from fissures," the US Geological Survey said.
