A brief history: in 1983, Kilauea started erupting out of Pu'o 'O'o. That eruption sent out multiple flows of lava, mostly south to the ocean, but one flank did threaten the access road to lower Puna--before dying within a few hundred feet of the road. In 2008, lava returned to the summit at Halemaumau crater, once again creating a lava lake there. Then, in April 2018, the big earthquake caused the lava to cease at both Halemaumau and Pu'o 'O'o. About a week later, lava came out in lower Puna, although the fresh Pu'o 'O'o lava didn't arrive until June I think. Meanwhile, the draining of the summit caused it to start collapsing in a periodic series of explosions.
To give a sense of how impressive the 2018 episode was, here's a link to the monitoring data for Kilauea: https://volcanoes.usgs.gov/volcanoes/kilauea/monitoring_data... -- the spike in earthquakes and deflation is the 2018 eruption stuff that made the news big time.
