Kīlauea 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 2x speed and circles Pu‘u ‘Ō‘ō, the vent region for the East Rift Zone eruption between 1983 and 2018. No major changes were observed in Pu‘u ‘Ō‘ō. The bottom of the crater was more shallow compared to previous overflights due to accumulation of collapse rubble.
