The eruption in Halema‘uma‘u, at the summit of Kīlauea, continues. Over the past week, the main source of lava effusion has shifted from the large eastern lake (right side of image) towards the smaller lake in the center of the crater (left side of image). This central vent has supplied lava towards the east that has poured into the eastern lake basin. The small fountain within the eastern lake has also shown renewed vigor in recent days.
