Mount Kilauea was for many years among the most active volcanoes in Hawaii and perhaps one of the most well known around the planet.
For nearly 35 years plumes of lava were observed coming from vents on the volcano's sides until April of 2018 when the activity became more intensified in some regions, ultimately being declared "dormant" later in September of the same year.

With sporadic activity during the last 10 months, active flow of lava was once again seen in the caldera from about 3:20PM local time.
There is little threat at present, but the USGS has increased local hazard warning levels and will continue to monitor the activity, while reporting will increase.
As far as tourism is concerned, it will be interesting to see how the current eruption progresses. It is as yet unclear if flowing lava may once again be enjoyed as a visitor experience. With many, many years of visitors counting the once in a lifetime experience as a highlight of visiting Hawaii.
