East Rift Zone overflight (March 4, 2021)
A routine helicopter overflight of Kīlauea's East Rift Zone allowed Hawaiian Volcano Observatory geologists to conduct an updated visual and thermal survey. This video is shown at 5x speed, and moves from west to east. At the western end of the region affected during the 2018 eruption, steaming remains in residential areas west of Highway 130. The video then enters Leilani Estates and Lanipuna Gardens subdivisions, where steaming is present over some of the 2018 fissures. The steaming originates from groundwater warmed by residual heat following the 2018 eruption.
