HVO geologists conducted a routine overflight of Kīlauea's East Rift Zone, from Pu‘u ‘Ō‘ō to the lower East Rift Zone flow field, on Tuesday, January 21. This photo looks uprift (west) and shows Fissure 8, the dominant vent for the 2018 lower East Rift Zone eruption. Minor steaming is normally present in and around the cone. USGS photo by M. Zoeller.
This thermal video of the fissure 8 cone shows that small areas of higher temperatures (greater than 100 degrees Celsius, or 212 degrees Fahrenheit) are present on the cone. Those hotter areas likely represent residual heat in the cone and the underlying fissure. USGS video by M. Patrick.
This video clip shows a flyover of fissure 8 on Jan. 21. During the 2018 eruption, lava spilled out from the cone into a channel that extended towards the north. Lava traveled approximately 13 km (8 miles) to reach the ocean at Kapoho Bay. USGS video by M. Patrick.

This photo looks north along the broad Fissure 8 channel. At its widest section, the Fissure 8 channel is about 430 meters (1400 feet wide). In the upper right section of the photo, Highway 132 can be seen cutting through the braided section of the channel. USGS photo by M. Zoeller.

This photo looks up the Fissure 8 channel, in the region just west of Kapoho Crater, where the flow widened and ponded during the 2018 eruption. The browner lava, with ridges, represents some of the final sluggish lava that covered the channel floor in early August 2018, just prior to Fissure 8 dying. USGS photo by M. Zoeller.

Black sand beach at the Isaac Hale Park on 21 January 2020. Basaltic sand from the 2018 lava delta (right) continues to accumulate, both widening and elongating the beach in Pohoiki Bay.

In the middle East Rift Zone, thick clouds and steam prevented clear views into Pu‘u ‘Ō‘ō Crater. A partial view into the crater showed an area on the south wall that had a small collapse over the past week. USGS photo by M. Zoeller.
