USGS scientists attach small metal bands, each with its own ID, to the ankles of adult waterfowl to identify where the animal was caught. When it is re-captured later in its migration, researchers can use that information to determine how far the animal traveled. 

Map as of 1:30 p.m. HST, June 2, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

An HVO geologist documents the fissure 8 flow southeast of Four Corners (the intersection of Highways 132 and 137).

As fissure 8 lava flowed into Green Lake, the lake water boiled away, sending a white plumehigh into the sky—visible from afar between around 11:30 a.m. and 1:30 p.m. HST.

Northern edge of the fissure 8 flow front on the night of June 1, as it approached the intersection of Highways 132 and 137, known as "Four Corners."

Overnight (June 1-2), fissure 8 lava fountains decreased to heights of about 50 m (164 feet). The moon can be seen in the upper left.

USGS scientists on HVO's overflight this morning (June 2) captured this image of the fissure 8 flow front as it advanced west along Highway 132. Around the time of this photo, 7:15 a.m.

This ‘a‘ā flow erupted from fissure 8 on Kīlauea Volcano's lower East Rift Zone on June 1, 2018, shows how the interior of a lava flow remains incandescently hot even though surface cooling forms a crust of solid rubble.

This animated GIF shows a pair of radar amplitude images that were acquired by the Italian Space Agency's Cosmo-SkyMed satellite system. The images illustrate changes to the calderaarea of Kīlauea Volcano that occurred between May 23 at 6:00 p.m. HST and May 31 at 6:00 p.m. HST.

Viewed from the intersection of Nohea and Leilani Streets at 10:15AM HST on June 1, the Fissure 8 lava fountain (to the right) appears to have decreased in height from previous sustained heights of 260 feet.
