Steaming area near Heiheiahulu
During a helicopter overflight on November 16, 2021, HVO scientists monitored a thermal steaming area near Heiheiahulu, on Kīlauea's middle East Rift Zone. The expanse of this thermal area has not changed or expanded significantly since the previous overflight of the area in March 2021. This view, from the north and looking south, shows two dark areas where vegetation has died due to heat from the steam. The steaming area is on the north side of older (200-400 years old) vegetated spatter cones. USGS image by C. Parcheta.
