Rainbow over the western fissure erupting in Halemaʻumaʻu crater

View to the north-northwest from the south rim of Halemaʻumaʻu crater and showing the activity at the western fissure, partly obscured by a rainbow. Today, the western fissure was erupting periodic small spatter bursts from the southwest vent of the fissure that is incandescent in this image and nearly as tall as the previously active cone to the right (northeast). Today, the lava lake is being fed by two sources at the base of the western fissure: the tubed-over lava stream entering the lava lake at the margin (initiated yesterday) and the small dome fountain (maximum height 5 meters or 16 ft).
