Kilauea, one of the world’s most active volcanoes, has been erupting on and off for nearly two months since it burst to life on Dec. 23. The eruption has been taking place at the volcano’s summit crater inside Hawaii Volcanoes National Park. No residential areas have been threatened by lava.

As Kilauea erupts a 330-foot-tall fountain of lava, officials warn of hazards from volcanic gas that may affect nearby communities.
