Aerial view of Halema‘uma‘u lava lake, January 12, 2021

A helicopter overflight on Tuesday, January 12, provided HVO scientists with high-angle views of the ongoing eruption in Halema‘uma‘u. The active west fissure is visible at left; displaying more incandescence after the resumption of visible lava fountaining over the weekend. The lava lake itself has a circulating western half, a stagnant eastern half, and several islands; all of this is surrounded by a perched levee that is now 1-2 meters (yards) tall. USGS photo by M.
